What I'm looking for

I’m looking to build scalable, reliable web and IoT products using React and .NET, solve production issues quickly, and ship with clean code and strong documentation—so deployments are smooth and systems stay stable.

I’m a Software Engineer with 3+ years of experience designing solutions and writing clear, high-quality code in JavaScript, React, C#, and Python. I evaluate code for accuracy and performance, troubleshoot complex problems, and write detailed technical documentation to keep teams moving fast.

In my roles, I’ve built reusable components and integrated frontend applications with backend services for real-time data processing. I also reduced website downtime by 30% across production environments through proactive troubleshooting, refactoring legacy code, and optimizing system architecture.

I’ve delivered real-world integrations between enterprise warehouse systems and IoT/smart home automation, configuring industrial handheld devices, wireless networks, TCP/IP, DHCP, and COM port communication. I enjoy cross-functional work where robust networking and reliable deployments matter, and I keep raising quality through peer code reviews.
