Suvarnidhi Tehnologies

Vijayawada, Andhra Pradesh · Product engineering

We build software
we own.

Suvarnidhi Tehnologies is a product company, not a services shop. Seven platforms across education and healthcare, each one designed, engineered and operated in house. Nothing on this page is a client project.

One content graph read by many exam blueprints Six subject concept groups on the left connect through a shared content graph to nine exam blueprints on the right. The blueprints do not own content; they map onto it. CONTENT GRAPH EXAM BLUEPRINTS
Ten exams read one graph of 979 concepts through 3,365 mappings.
An exam owns no content. Adding one is a mapping exercise, not an engineering one.

How we work

Four decisions that shape everything we ship.

These are not aspirations. Each one is visible in the schema, the deployment pipeline and the invoices.

Ownership

Products, not projects

We do not sell hours. Every line we write becomes an asset on our own balance sheet, with its own users, its own revenue and its own roadmap. The compounding is the point.

Architecture

Configuration over code

Content, language and exam structure are data, not code. Subject names appear in no application file. Opening a new market is a provisioning and content exercise, which is why one engine can carry four education products.

Integrity

Server-authoritative where it counts

Scores, entitlements and money are decided on the server, never the client. Exam papers ship without the answer key. Row-level security is on every table, and privilege guards sit under the ones that matter.

Economics

Content is manufactured, not licensed

We built the pipeline that authors, independently verifies and publishes our own curriculum. Runtime AI is sized so unit economics work at scale rather than only in a demo.

Portfolio

Seven platforms, two families.

Four education products share a single assessment and learning engine. Three independent products serve their own markets. Status below is stated plainly: live means real users and real money.

The Astrel engine family

One engine · four markets

Astrel Intermediate

Live

Bilingual exam preparation for Class 11 and 12 · Andhra Pradesh & Telangana

A complete preparation platform for Intermediate students, delivered in English and in Telugu, sold both directly to students and to colleges by the seat. Students get lessons, a practice bank, animated step-by-step whiteboard solutions with audio narration, a grounded AI tutor that accepts typed questions, a photograph of a problem or a spoken doubt, computed exam readiness against a real paper pattern, a study plan that rebalances itself every time it is opened, and a social layer of duels, leagues, study rooms and squads.

Colleges get a separate portal: cohorts, custom named staff roles with per-permission access, section-scoped lecturer visibility, lecturer-authored timed examinations that grade and rank themselves, per-student mistake analysis, and self-serve billing. A dedicated exam-hall application delivers supervised tests on desktop.

Every number a student sees is real. Mastery is difficulty-weighted, recency-weighted and shrunk toward the mean on low volume. A new account honestly shows zero.

Surfaces
Student mobile app, student web LMS, exam-hall portal, platform admin, college portal, field-sales portal, partner reporting portal, public site. Eight applications on one backend.
Content
10 subjects · 175 chapters · 979 concepts · 915 lessons · 10,727 questions · 3,785 previous-year question appearances

Astrel Competitive

In build

Government recruitment, defence and postgraduate entrance

The same engine pointed at adult candidates rather than school students. Government recruitment (UPSC, SSC, Banking, RRB), defence and state service commissions (NDA, CDS, APPSC, TSPSC, DSC) and postgraduate entrance (GATE, CAT, GRE).

It runs as a fully isolated deployment with its own database and its own release train, which is the practical proof of the engine claim: a second product, configured rather than rewritten.

State
Engine complete. Taxonomy seeded with 23 subjects and 20 exam blueprints. Curriculum authoring in progress.
Isolation
Separate database, separate package scope, separate mobile application identity. No shared runtime with the school product.

Astrel School

Planned

Foundational and secondary schooling

Extends the platform downward from Intermediate into school years, on the same architecture as Astrel Intermediate. It inherits the bilingual content model, the institution portal and the examination engine unchanged, and reuses the same college relationships already being built in Andhra Pradesh and Telangana.

Basis
Architecturally identical to Astrel Intermediate. Curriculum, taxonomy and blueprints differ; the engine does not.

Astrel International

Upcoming

A multi-tenant certification engine for markets beyond India

The generalisation of everything above. Two structural changes make it work. Language became data instead of columns: every human-readable field is locale-keyed, with a registry carrying writing direction, numeral system and decimal separator, and a per-tenant fallback chain, so a missing translation degrades visibly for an author and gracefully for a candidate rather than rendering blank. Taxonomy became data instead of literals: no subject name appears in application code at all, so a nursing tenant and an engineering tenant share every line.

Right-to-left support is one attribute and a stylesheet with no physical inline-axis properties in it, not an override sheet. A tenant is resolved from the hostname, and a user belongs to exactly one tenant, so a cross-tenant read is not expressible rather than merely rejected.

State
Engine built and verified against a live database. Two pilot tenants seeded and sat end to end.
Verification
32 engine unit tests · 56 tenant-isolation checks against the public API surface · 18 end-to-end checks per tenant · 80 content items validated
Deployment
Two commercially distinct products served by one worker per application. The hostname selects the tenant.

Pleroma

Live

A dual-track faith and academics education platform

Pleroma teaches an academic curriculum and a faith curriculum side by side, so a learner meets both in the same lesson rather than in separate apps. It spans a digital university carrying Cambridge Lower Secondary and American standards curricula, an interactive biographies library, structured analysis across all 1,189 Bible chapters, a daily five-minute study habit with streaks and weekly leagues, a scripture-grounded AI assistant, printable Sunday school material, and congregation features for groups, announcements and prayer requests.

Pleroma is live and serving learners today. It is being rebuilt in parallel as a codebase we own outright, shipping to web, iOS and Android from one TypeScript source. That migration removes a feature ceiling and a per-seat platform cost we do not control, and it brings the product onto the same foundations as the rest of the portfolio.

Subsystems
Pleroma Digital University, Biblical Biographies, Chapter Catalyst, 5 Minute Master, Pleroma Intelligence, Sunday School, Congregations
Rebuild
114 data models mapped, foundation schema written, original record identity preserved through the import so nothing is orphaned
Stack
Next.js, Expo, Supabase, shared TypeScript package across web and mobile

The Conversation Group

Nearing release

AI-mentored course delivery for ministry organisations · formerly Wellspring Collegium

Partner organisations already run correspondence-style courses with human mentors who guide a learner through specific material. The Conversation Group gives them a mentor that scales: it teaches one course's actual content, tracks where the learner has reached in it, and answers in the voice of that course rather than as a generic assistant.

The content pipeline is deliberately human-gated. An administrator submits the course material, the system structures it into modules, lessons, objectives and interactive elements, and nothing reaches a learner until a person has reviewed and approved it. There is no auto-publish path.

State
Substantially complete. In final build ahead of release with partner organisations.
Reach
One codebase to iOS, Android and web
Safety
All AI calls proxied server-side. No provider key ever reaches a browser or a device.

ClinicFlow

In build

Clinic operations, one surface per role

Our move out of education. Most clinic software gives every role the same screen and asks them to find their part of it. ClinicFlow builds a purpose-made surface for each place in the clinic instead: a reception desk application, a consulting-room application for the doctor, a waiting-lounge display, a patient mobile application, and an administrative back office.

Appointment scheduling and patient messaging over WhatsApp are first-class parts of the system rather than bolted-on integrations.

Platform

What the engineering actually consists of.

The portfolio is only credible if the machinery under it is. This is the machinery, stated without adjectives.

Bilingual by architecture

English and Telugu are equal citizens in the data model, not a translation layer bolted on afterwards. Telugu is written the way students actually speak it, with technical terms kept in English inline.

Mathematics that renders offline

The full typesetting engine and its fonts ship inside the application. A student on a weak connection in a district town sees the same equations as one on fibre. No runtime request to a content network.

Animated whiteboard solutions

Every question carries a symbol legend, a step-by-step board that draws itself, a spoken narration and a written walkthrough, each with a Telugu counterpart.

Measurement, not vanity metrics

Mastery weights question difficulty, decays with age, accounts for time taken against an expected time, and shrinks toward the mean until there is enough evidence. Readiness combines syllabus coverage, mastery and mock performance.

Examinations that cannot be gamed

Papers are served without the answer key. Grading, ranking and timing run on the server under elevated privilege. Ranks and reviews unlock only after the window closes, and staff see integrity flags students never can.

Security as a default, not a review

Row-level security on every table. Database triggers block a signed-in account from editing its own role, institution or subscription. One device slot per account, with the displaced session revoked at the source.

AI sized for unit economics

The runtime tutor uses a fast, inexpensive model with prompt caching and a server-enforced monthly cap, so an answer costs under a rupee. Heavier models are reserved for authoring, where the cost is paid once and amortised across every student.

A real quality programme

A dedicated testing portal with 297 written test cases across nine surfaces, a pool of pre-provisioned accounts covering every entitlement state, and a full staging mirror so destructive and payment flows are never rehearsed in production.

Delivery without a person in the loop

Every application deploys from continuous integration on push. Mobile builds go through a managed pipeline to both stores. Scheduled jobs handle reminders, billing transitions, digests and notifications on their own.

Business model

Free where it costs us nothing. Priced where it costs us something.

Lessons and the full question bank are free forever, because their marginal cost is close to zero and they are the strongest acquisition wedge we have. We meter the one feature that carries a genuine per-use cost, and we sell to institutions by the seat.

Payment paths
Three, all in live operation: direct student subscriptions, self-serve institutional upgrade, and field-sales invoicing with GST.
Store compliance
Consumer subscriptions are sold on the web and unlocked in the mobile app, the standard route for digital goods. The app carries no in-app price or checkout.
Cost discipline
Curriculum is authored in-house rather than licensed, and the runtime AI cap is enforced on the server. Gross margin does not degrade as usage grows.
