My Journey

2018

The Beginning

Started my journey as a junior developer, learning the fundamentals of web development and software engineering principles.

2019-2020

Full-Stack Development

Dove deep into full-stack development, mastering React, Node.js, and databases. Built my first production applications.

2021-2022

Cloud & Architecture

Expanded expertise in cloud platforms (AWS, Azure), microservices architecture, and DevOps practices.

2023-2024

Senior Engineering

Led technical teams, architected scalable systems, and mentored junior developers. Focused on performance and best practices.

About My Work

I'm a software engineer passionate about building high-performance, fully on-chain decentralized exchanges — blending deep blockchain architecture with the creativity of modern AI-assisted coding. I focus on delivering secure, scalable, and maintainable systems that perform beautifully under real-world load.

I've designed and deployed custom blockchains using BFT-based consensus, managed validator networks, and implemented on-chain order books capable of handling tens of thousands of transactions per second. My experience spans spot, perpetual, and hybrid trading markets, with a relentless focus on speed, fault tolerance, and security at every layer.

As a senior software engineer, I bring expertise in system design, scalable architecture, and engineering best practices. I've architected distributed systems handling millions of requests, implemented microservices patterns, and designed fault-tolerant applications. My approach combines SOLID principles, design patterns, clean code practices, and performance optimization to deliver production-ready systems.

I thrive in AI-driven development environments, using tools like Cursor, Copilot, Claude, and ChatGPT to iterate faster, refactor cleaner, and maintain peak productivity without sacrificing code quality. My core stack includes Rust, Go, TypeScript, Solidity, and Node.js, supported by Docker, Kubernetes, Grafana, Hardhat, and Foundry for reliable infrastructure and testing.
