About

I am a Full-Stack Engineer focused on performance, scalability, and shipping production-grade software.

Currently building tools and platforms that make developers' lives easier. I work across the stack, specializing in TypeScript, React, and Solana development.

  • Built interactive developer tools like Heliora — Solana's first AI-native prediction protocol, leveraging autonomous agents and smart contracts.
  • Developed real-time systems like a Rust-based CEX Orderbook using Redis pub/sub queues for low-latency matching.
  • Specialized in building scalable full-stack applications using Next.js, Node.js, and PostgreSQL, bridging the gap between complex logic and fluid UI with products like SmartInvoice and foOm.

Achievements

Milestones & Learning

A summary of my problem-solving experience, technical achievements, and areas of continuous study.

DSA Problem Solving

LeetCode & GeeksforGeeks

Solved 250+ DSA problems across LeetCode and GeeksforGeeks, covering graphs, DP, trees, shortest paths, and greedy algorithms.

Solana Development

Learning by Harkirat Singh

Building on-chain programs using Rust and the Anchor framework on Solana. Explored decentralized prediction markets, PDAs, SPL tokens, and AI-native protocol design through projects like Heliora.

System Design Study

Self-paced Study

Studied High-Level System Design (HLD) principles for building scalable distributed systems. Explored core concepts including horizontal & vertical scaling strategies, caching layers (Redis, CDN), database optimization (sharding, replication), load balancing, microservices architecture, API design patterns (REST, gRPC), message queues (RabbitMQ, Kafka), CAP theorem, and trade-offs in distributed systems.
