Full Stack Developer crafting scalable systems with clean architecture and real-world impact.
About
I scale systems only after understanding failure modes.
Full Stack Developer with 3+ years of experience building scalable web and mobile applications. Strong background in backend systems, performance optimization, and AI-powered products.
I focus on solving real problems with clean architecture and measurable impact. From reducing API response times by 30% to handling 10,000+ concurrent users, I build systems that scale.
Based in Goa, India, and open to remote opportunities.
Projects
Every technical decision is a trade-off. I document the problem, constraint, and reasoning.
Real-time Chat Application
Problem: Need real-time messaging at scale without sacrificing message reliability.
Constraint: Must handle 10,000+ concurrent connections with sub-100ms latency.
Decision: Chose Socket.io for real-time transport, PostgreSQL for persistence, and Redis for pub/sub to decouple scaling concerns.
10,000+ concurrent users
AI Blogging Platform
Problem: Generate high-quality content at scale while maintaining SEO and readability.
Constraint: API costs must remain predictable, and content must pass human quality checks.
Decision: Built a pipeline that generates drafts, validates quality, then optimizes for SEO—separating generation from optimization.
5,000+ articles generated
Serverless Processing System
Problem: Process variable workloads without maintaining always-on infrastructure.
Constraint: Must handle both batch and real-time streams, with cost optimization as a priority.
Decision: Used AWS Lambda for compute, Kafka for event streaming, and S3 for durable storage—paying only for actual processing time.
Image Manipulation Tool
Problem: Enable complex image operations in the browser without blocking the UI.
Constraint: Must work on mid-range devices and handle large images without crashing.
Decision: Moved heavy processing to Web Workers, used Canvas API for rendering, and implemented progressive loading to keep the main thread responsive.
3,500+ active users
Secure Document Sharing App
Problem: Share sensitive documents securely without trusting the server.
Constraint: Encryption must be transparent to users, and key management must be foolproof.
Decision: Implemented end-to-end encryption with client-side key generation, using native encryption libraries for performance and security.
Experience
I choose roles where I can own outcomes, not just complete tasks.
