Systems I've built

Production systems with measurable impact — not side projects.

Enterprise CRM Integration Platform

Problem

Multiple enterprise clients needed automated data synchronization across Salesforce, HubSpot, Microsoft Dynamics 365, and EquipSoft — each with different schemas, APIs, and data models.

Architecture

Built event-driven data pipelines using AWS Lambda for serverless processing, PostgreSQL for persistent storage, and custom API adapters per CRM platform. Implemented retry logic, data validation layers, and monitoring dashboards.

Impact

  • Automated data sync for 3 enterprise clients
  • Eliminated manual data entry processes
  • Zero data loss across 100K+ record migrations

Full-Stack Web Platform — 10K+ Users

Problem

Client needed a production web application built from scratch to serve 10,000+ end users, with authentication, admin dashboards, and real-time data processing.

Architecture

React frontend with server-side rendering, Node.js API layer, PostgreSQL database with optimized queries, and AWS infrastructure. Implemented CI/CD pipeline with automated testing and staged deployments.

Impact

  • Serving 10,000+ active users in production
  • Reduced deployment time via CI/CD automation
  • Delivered full build independently from architecture to deployment

Revyu — Shopify Review Platform

Problem

Shopify merchants lacked an integrated, AI-powered review management system that could drive customer engagement and provide actionable insights from feedback data.

Architecture

Full-stack Shopify app with React storefront widgets, Node.js backend for review aggregation and AI processing, Firebase for real-time data sync, and Shopify API integration for seamless merchant onboarding.

Impact

  • Scaled to 500+ active merchants with 99.5% uptime
  • Increased user engagement by 35%
  • Reduced support tickets by 25% via self-serve changelog and feedback modules

MessedUp — Hostel Management System

Problem

University hostel facilities managing 500+ students relied on manual processes for mess billing, attendance tracking, and fee collection — leading to errors and administrative overhead.

Architecture

Web application with React frontend, RESTful API backend, Firebase for real-time sync, PostgreSQL for billing data, and Google Apps Script for automated report generation and email notifications.

Impact

  • Reduced administrative overhead by 75%
  • Automated bill generation for 500+ students
  • Deployed across multiple CUSAT hostel facilities

I build systems that scale before they need to.

Product-minded engineer focused on architecture, performance, and measurable impact. Technology-agnostic — I pick the right tool for the problem, not the other way around.

Systems over features

I design for scale from day one. Clean abstractions, modular architecture, and infrastructure that doesn't need to be rewritten in six months.

Ship fast, ship right

Velocity matters, but not at the cost of reliability. I optimize for fast iteration cycles with strong CI/CD practices and automated testing.

Measure everything

Performance budgets, error rates, deployment frequency. Every decision is informed by data, not assumptions.

Let's build something

Open to full-time roles, consulting, and technical collaborations.
