Enterprise-Grade Websites, Apps & Software Built for Growth
Anyone can build a prototype. We build the systems your business can actually depend on.
From secure architecture and seamless payments to scalable applications, intelligent automation, and reliable deployments, we engineer digital products for real customers, real operations, and long-term growth.
Products and client sites running in production
Ten products and client sites, every one running in production on infrastructure we administer
Products running in production, not concept decks.
Geeta Sri Retina Institute
An eye clinic’s site with a real patient portal behind it — OTP sign-in, booking, a live queue and per-visit report PDFs — and an AI assistant that answers in Hindi, English or Hinglish, opens the matching patient-education panel, and sends anything urgent to the booking form instead of guessing.
VixitAI Clinic
A hospital management system in daily clinical use — appointments, EMR, lab, pharmacy, imaging and billing, with per-tenant isolation and audit logging throughout.
VixitAI Cortex
A retrieval layer over an organisation’s own documents: ingestion with OCR fallback, chunking, vector search and cross-encoder reranking — behind an evaluation harness that fails the build when answer quality regresses, so a prompt change cannot quietly make things worse.
Rentlelo
A peer-to-peer rental marketplace with geospatial search and real-time chat, where privacy is a schema decision rather than a setting: phone numbers never appear in a listing response, only behind a rate-limited reveal.
Upper Bazaar
A bilingual marketplace for local workers and shops — profiles, orders, delivery dispatch and scheduled slots — with installable apps for riders and shops that still open when the signal does not, and queue actions taken offline.
Sahajyoga ERP
Event operations end to end — registration, payments, accommodation, volunteer assignment and check-ins — built deliberately self-contained, so it can be lifted onto its own server without unpicking it from anything else.
CricAI
Live scores and match analytics with a server-rendered content layer built for search.
Kosha News
A Hindi news site on a custom WordPress theme, with a render cache invalidated on publish that takes a cold page from 171 queries to none on a warm hit.
Vixit News
A news surface rebuilt for Core Web Vitals — mobile Lighthouse 65 to 95 and LCP 6.5s to 2.6s, by cutting the page from 2,692KB to 764KB rather than by adding a caching plugin on top.
VixitAI Ecosystem
The ecosystem everything above belongs to — healthcare, news and the smart tools around them under one roof, with the shared auth, shared billing and deployment discipline that keeps a dozen services on one box behaving.
What we actually do, in the order it usually matters.
Backend and data
Node and Express APIs over tenant-isolated PostgreSQL, with the isolation boundary chosen deliberately rather than by default. Redis for queues and cache. Money paths get the same treatment as data — idempotent payment webhooks, recurring mandates, GST-inclusive invoicing — and atomic, race-tested counters sit behind every human-readable identifier, because SELECT MAX + 1 works right up until two requests land in the same millisecond.
- PostgreSQL + Redis
- Role-based access control
- Payments and invoicing
- Audit logging
- Race-tested ID counters
AI that is load-bearing
Assistants that hold their persona and safety rules on the server where a browser cannot edit them, answer in the language they were asked in, and return structured output the interface can act on rather than a wall of text. Retrieval-augmented generation with hybrid vector and full-text search, reciprocal rank fusion and cross-encoder reranking. Multi-provider fallback so one slow vendor does not stall a request, per-tenant token metering so inference cost never surprises anyone, and evaluation harnesses so a prompt change cannot quietly regress an answer.
- Chatbots and assistants
- RAG pipelines
- Provider failover
- Token metering
- Evaluation harnesses
Shipping and staying up
PM2 cluster mode behind nginx, zero-downtime reloads, TLS that renews itself, and off-site backups that are restored and checked rather than assumed — a backup job reporting success while uploading nothing is the failure worth engineering against. Health checks alert a human. Deployment is a script that runs the same way every time, not a sequence someone remembers.
- PM2 + nginx
- Zero-downtime deploys
- Verified backups
- Auto-renewed TLS
- Monitoring and alerts
Numbers we can show you the run for.
No compliance badges and no uptime guarantee — those mean an audit or an SLA with money behind it, and we do not have either yet. These are Lighthouse runs.
Rebuilt to remove render-blocking third parties and self-host every font.
A live marketplace, improved without changing what the product does.
Responsive image renditions and a font payload cut to what the page actually sets.
Metric-matched font fallbacks and reserved media boxes on a WebGL page.
How an engagement runs
We start with a written architecture note — data model, tenancy boundary, auth model, and the three things most likely to bite. It is short, and it is the most valuable document in the project, because it is where disagreements surface while they are still cheap.
Then we build in vertical slices you can actually use, not horizontal layers you have to take on faith. You see a working thing early and you keep seeing working things.
After launch we keep operating it. Every product on this page runs on infrastructure we administer ourselves, which is why the failure modes described above are ones we have actually met rather than ones we have read about.

A short description of the problem is enough to start. If it is not something we should take on, we will say so.
