Software Engineer
I’m a backend-heavy full-stack engineer with deep experience in Golang, building robust, scalable systems for fintech, SaaS, and platform-based products. I’ve designed and deployed production-grade APIs, background workers, cron jobs, and third-party integrations using tools like Gin, NestJS, and Python.
My core strength lies in backend architecture — I’ve built secure, high-performance systems in Golang, including JWT-based authentication, custom API key infrastructure, Slack bots, and real-time services, all with clean, testable, and maintainable code.
I’ve built and maintained over 10 production-grade golang libraries to solve real-world problems across API consumption, background tasks, and service integrations. I'm deeply passionate about the Golang ecosystem and actively contribute to its growth through tooling, open-source projects, and community support.

I’m also proficient with React/Next.js, Docker, MongoDB, PostgreSQL, AWS, FCM (Firebase Cloud Messaging), and agile tools like Jira and Asana.
Currently I’ve been diving deeper into Web3, decentralization, and smart contract integrations. I’m looking for remote roles in Web3 backend development, infrastructure, or smart contract tooling, where I can contribute to high-impact projects in DeFi, wallets, or developer platforms.
Let’s build the future of the internet.
