I build & lead teams that ship entire platforms.

Co-founded, with every line of engineering mine, and live in production: 22 tools across two strictly isolated tracks (NEET UG and NEET PG with INI-CET), an agentic coach streaming over SSE from self-hosted LLMs behind four layers of scope guardrails, and six Dify RAG agents grounding answers in counseling knowledge. The data layer parses column-major MCC allotment PDFs into 95,384 PG allotments at 96.9% read accuracy, syncs UG round results hourly, and refreshes an 823-college NMC directory nightly. Sells courses over UPI with webhook-settled payments, and ships as an Expo React Native app on TestFlight and Play internal testing through Codemagic cloud CI, with iOS signed via the App Store Connect API without touching a Mac. Runs entirely on a self-administered VPS.

A full-stack appointment-booking and operations platform for salons, spas, barbers, clinics and more. I designed and built the entire system solo: a Flutter customer app on the Play Store, a multi-subdomain Next.js web app serving six personas (customer, partner, employee, inductor, admin, super-admin), and a hardened FastAPI backend on PostgreSQL with Firebase Phone Auth, TOTP MFA, no-show fines, a subscription plus multi-level commission ledger, and role switching shared across subdomains.

A production Flutter super-app, a monorepo of feature packages sharing one shell. Discovery feed, reels, venue and table booking, group and event bookings, bidding flows, a wallet and branded payments, all behind a flavor-driven build pipeline (production, QA, staging, develop) with Melos and FVM for multi-package orchestration.

A production Flutter app for venue owners: table and group-booking management, event creation, cost-to-bid and bid handling, menu management, wallet and accounting, artist hiring, brand setup, subscriptions, reviews and call support. Same flavor-driven Melos monorepo as the customer app, sharing domain and data packages.

A production party-and-venue booking platform: venue discovery, table & event bookings, group bookings and payouts. I led engineering across the React web app, Flutter customer and partner apps, and the CodeIgniter plus Node backends, authoring nearly half of all engineering commits.

Single payment flow spanning Razorpay, Paytm, Stripe and Easebuzz with wallet co-funding, coupon engine, reward issuance and S2S webhook firewalling, engineered so gateway callbacks bypass the strict API firewall without weakening it.

Solo-built backup platform: AES-256-GCM encrypted MySQL dumps shipped to Cloudflare R2 with daily/weekly/monthly retention, TOTP-MFA dashboard, one-click restore, audit logs and email health reports.

Call-center pipeline that pulls Smartflo recordings, transcribes them with AssemblyAI, summarizes with a locally-hosted LLM (Ollama), and emails AI-generated daily reports through an async queue with retry workers.

WhatsApp bot on Meta Cloud API wired to Dify AI: persistent conversation sessions, message deduplication, per-user queues, typing indicators and full conversation logging to MySQL.

Freelance build for a Chennai dental clinic: a fast static front end backed by a PHP practice-management API covering appointments, patients, treatments, prescriptions, invoices and staff, with WhatsApp notifications, PDF generation and a Meta lead webhook. The SEO work is the differentiator: Dentist-type JSON-LD with geo and opening hours, locality-targeted titles and metadata, Open Graph and Twitter cards, canonical URLs, forced-HTTPS 301s and GA4, putting the clinic on page one for its neighborhood searches.

Re-architected the platform's perimeter: VPN-only admin domain, public/partner gateway segmentation, automated SSL via Cloudflare DNS-01, Apache hardening, centralized API firewall with app-secret validation, all while keeping payments and 16 cron automations running.
