Projects

React Node.js PostgreSQL Redis Typescript Docker Express nginx

easyurl.in — URL Shortener & Analytics

Developed a full-stack URL shortener with real-time click analytics breakdowns by country, device, browser, OS and language
Implemented Redis cache-aside pattern for sub-millisecond redirects with 15-minute TTL and immediate invalidation on link updates
Analytics engine with dynamic time bucketing daily/weekly/monthly GROUP BY switching based on date range to prevent chart compression
Anonymous shortening with IP-based rate limiting (3 links/3 hours) tracked in Postgres; authenticated accounts get permanent links with full analytics
Google Safe Browsing v4 integration with a local domain escalation system 5+ flags on the same domain triggers an admin review queue
Deployed on Oracle Cloud ARM64 VM with Docker multi-stage builds, nginx reverse proxy, and Let's Encrypt SSL

Intern Flow — AI-Powered Internship Management

Built a 7-role internship pipeline (HR, Mentor, Referrer, IT, Security, Legal, Program Owner) with a stage-gated workflow engine enforcing valid transitions across an 8-stage happy-path lifecycle, from referral to certificate issuance
AI resume parsing with a dual-provider fallback chain — Anthropic Claude primary, Gemini Flash fallback — processed asynchronously via BullMQ with live status pushed to the client over SSE
NDA e-signature flow using single-use Redis tokens with 7-day TTL, advancing the workflow atomically on signature and firing role-scoped notifications on completion
SLA monitoring with automatic breach detection and 3-tier escalation, backed by a startup recovery scan and 30-minute re-enqueue sweep so scheduled reminders survive Redis restarts or worker downtime
Real-time in-app notifications over WebSockets, grouped by referral and scoped per role, alongside a cost-optimized AI FAQ assistant that only invokes the LLM for 5 of 12 query types — the rest resolve from parameterized SQL
Migrated the self-hosted stack (Postgres, Redis, MinIO) from AWS (RDS/S3) to a bare-metal Oracle Cloud ARM64 VM via Docker Compose, isolating database roles and Docker bridge networking from a second production app on the same host

AI in my work

Where AI made my work measurably better.

A selection of AI initiatives I designed, built, and championed to accelerate engineering, automate workflows, and deliver measurable business impact.

AI-DRIVEN PRODUCT KNOWLEDGE BASE PIPELINE

Designed an automation pipeline that extracts product data into structured JSON, then feeds it to an LLM to auto-generate structured .md analysis documents.
Slashed developer analysis time by 98% (from 2 days to 30 minutes), significantly reducing resource dependency and accelerating overall project delivery for the business.

INTERN FLOW — AI-POWERED INTERNSHIP MANAGEMENT PLATFORM

Led end-to-end development of an AI-augmented workflow platform for Hexaware's internship lifecycle, including AI resume parsing (Gemini Flash) and an AI FAQ chatbot.
Decreased HR overhead by 90% by centralizing months of parallel email communications into a single platform.

AI-ASSISTED TESTING INITIATIVE

Pioneered the implementation of tSQLt testing within the department, leveraging GitHub Copilot to rapidly author test scripts and accelerate codebase comprehension.
Established a new quality assurance standard that was subsequently adopted by the entire engineering team.

AI TOOLING & REVERSE MENTORSHIP

Reverse-mentored senior engineers (15+ years of experience) on implementing effective AI-assisted development workflows.
Successfully drove the upward adoption of modern AI tooling across the organization, boosting developer productivity and demonstrating technical leadership.
