Xpecto IT Solutions Pvt Ltd

Built a grocery price-comparison platform end to end — database schema, backend services, REST APIs, and React.js frontend. Engineered a Node.js pipeline with Puppeteer and Cheerio ingesting 2,000-3,000 products daily from Zomato, Swiggy, DMart, Blinkit, and BigBasket, adding rotating proxies and cron scheduling to cut scrape failures. Designed REST APIs for product search, price history, and comparison, tuning queries and indexes for large datasets. Containerized services with Docker, deployed and monitored on AWS EC2, and owned bug fixes and performance tuning post-launch.

Office Sahayogi

Developed Business Management Software automating finance operations — sales, purchase, journal, and return transactions — with automated balance sheet, P&L, trial balance, and ledger generation. Designed the PostgreSQL data model with Prisma ORM (normalized schema, migrations, indexing/query optimization for heavy reporting workloads). Architected a NestJS modular monolith with Redis and BullMQ for background jobs using an outbox pattern for idempotent downstream writes. Built an internal Code Review Platform as a NestJS module (GitHub App, webhooks, a configurable rule engine with AI-assisted review, check runs published as merge gates in a Next.js dashboard). Integrated TallyPrime with a WhatsApp gateway via TDL for automated customer notifications, and built a real-time attendance service on a biometric device protocol. Authored architecture docs, API specs, and ADRs.

Featured Work

Projects that make an impact.

Real-Time Ticket Booking System

A high-concurrency seat-booking system using Redis distributed locks with TTL and atomic Lua scripts to guarantee no double-booking under simultaneous requests, with automatic seat release on payment timeout. Live seat-availability updates are pushed to clients over WebSockets, and a Redis-backed waiting queue absorbs traffic spikes during high-demand ticket drops.

Event-Driven E-Commerce Platform

Decoupled order, payment, inventory, and notification services communicating over Kafka topics with consumer groups, replacing synchronous calls and isolating failures between services. Implements idempotent consumers with offset management and a saga-based order workflow with compensating transactions, plus dead-letter topics and retry handling for failed events.

Developer Portfolio (AI-Assisted Build)

A responsive portfolio (this site) built using an LLM-assisted workflow with Claude Code for scaffolding, refactoring, test generation, and documentation — cutting build time while keeping full review over every piece of generated code.

Get to know me

About who I am.

I'm a Full Stack Developer with 2.5+ years building production web applications end to end — schema design, REST API development, and responsive React frontends. Hands-on with Node.js, NestJS, Express.js, Python, React.js, Next.js, TypeScript, PostgreSQL, and MySQL, including indexing and query optimization.

I'm experienced with distributed and event-driven systems using Redis, BullMQ, and Kafka, and I deploy on AWS with Docker and CI/CD. I use LLM tooling (Claude Code, GitHub Copilot) daily for scaffolding, code review, debugging, and test generation.

Building reliable, scalable systems — from schema design to production deployment.
