Featured Engineering Projects
VelocityAI — Autonomous AI Product Delivery & PR Review SaaS
🚀 Autonomous AI Cockpit- Architected a Turborepo Monorepo (1 Next.js 16 App, 7 shared internal packages) with unified end-to-end type safety across PostgreSQL, Drizzle ORM, tRPC v11 (14 sub-routers), and TanStack Query, eliminating API schema drift.
- Engineered an Autonomous PRD-Aware GitHub Code Reviewer using Vercel AI SDK & Octokit that parses multi-file Git diffs, validates code against individual PRD acceptance criteria, calculates mathematical compliance scores (0–100%), and posts inline blocking/warning comments; slashed PR review turnaround time from 48 hours to under 3 minutes (94% reduction).
- Built an Event-Driven Durable Background Pipeline via Inngest with idempotent step.run checkpoints and automatic inline fallbacks for AI PRD generation, task decomposition, and PR auditing, ensuring 99.9% fault tolerance with 0 dropped webhooks and zero duplicate LLM token costs on retries.
- Developed an AI Copilot with Git Data API Integration that indexes repo AST & file trees into structured context snapshots; features 3 operational modes (Build, Fix Review, Improve) that autonomously draft multi-file patches, create Git commits (blob → tree → commit → ref), and open Draft Pull Requests in a single click, saving developers 4–6 hours per feature.
- Implemented Multi-Tenant Role-Based Access Control (RBAC) via BetterAuth with edge middleware cookie checks and no-store bfcache prevention, real-time WebSocket state synchronization using Pusher Channels, and metered credit-based billing via Razorpay with HMAC SHA-256 signature verification and idempotent event ledgers.

MailOS — Keyboard-First AI Command Center
- Full-stack productivity SaaS integrating Gmail and Google Calendar via multi-tenant OAuth with a streaming AI agent executing 5 function-calling tools.
- Implemented pgvector semantic search (1536-dim embeddings) and automated priority classification via real-time Gmail Push Notification webhooks.
- Engineered keyboard-first UX featuring 15+ vim-inspired shortcuts and fuzzy ⌘K command palette with <50ms query response times.

My Form — AI-Native Conversational Form Builder SaaS
- Architected a Turborepo monorepo with 2 applications and 7 shared packages, achieving 100% compile-time type safety from PostgreSQL through Drizzle ORM → tRPC v11 → React Query.
- Implemented natural-language form creation, streaming conversational follow-up questions, and semantic submission summaries using Vercel AI SDK.
- Built a high-performance conversational form runner with 5 animated presets and custom JWT auth with refresh token rotation and reuse detection.

Kavach — AI-Powered Personal Safety Companion
🏆 Top 30 / 150 — PromptWars Hackathon Winner- Ranked in the Top 30 out of 150 participating students at PromptWars x GDGoC MM(DU) Hackathon.
- Engineered a deceptive incoming-call cover screen with silent duress code detection, allowing victims to trigger emergency alerts without visual indicators.
- Calculates walking directions to the 3 nearest verified SafePoints (pharmacies, security desks, warden posts) using Leaflet and OpenStreetMap.
- Built a dual-mode urgency scoring engine with Google Gemini (via Vercel AI SDK) with a deterministic 2.5s rule-based fallback, guaranteeing <3s scoring latency.
- Achieved <2s real-time alert dispatch to guardians via Socket.io with live GPS breadcrumb tracking and battery monitoring.

Reclaim — Autonomous AI Revenue Recovery Agent
⚡ Razorpay AI Buildathon 2026- Engineered an autonomous AI revenue recovery agent built natively on Razorpay APIs across three dedicated recovery lanes (payment degradation, checkout abandonment, B2B invoices).
- Architected a zero-hallucination Two-Tier Separation of Concerns: deterministic policy engine (0ms latency, strict 9am–7pm IST boundaries, 4h cooldowns) paired with Gemini 2.0 tone generation.
- Achieved 77.3% measured net recovery rate with append-only cryptographic audit logs compliant with India's DPDP Act 2023.
- Authored 122 automated tests (93 Vitest backend tests, 29 frontend tests) with zero accessibility violations.
