Senior backend engineer building scalable, high-performance systems with Python, Node.js, Go, and blockchain.
What I'm looking for
I’m a Senior Software Engineer with 8 years of experience building web and mobile applications, specializing in Python, Node.js, Go, and Java. I’m especially energized by designing scalable, high-performance systems that support business growth and long-term strategy.
At TFDGroup, I led the design and development of scalable backend systems, architecting microservices-based solutions integrated with third-party services. I improved scalability and reduced latency, implemented new features in a CI/CD environment, and provided technical leadership and mentorship to junior engineers.
Previously at Acme Software Int, I designed, developed, and maintained web applications using Node.js, Go, and Python—delivering a 20% increase in efficiency and user engagement. I also implemented blockchain-based solutions for DeFi platforms and marketplaces using Solidity and Rust, contributing to architecture discussions focused on scalability and performance.
Earlier, at Deveera, Inc, I built and maintained backend systems using Java, Python, and JavaScript, including secure API integrations and scalable database solutions. I led migrations to modern, scalable cloud architectures (reducing operational costs by 15%) and collaborated with QA on automated testing to improve codebase reliability—always with an agile mindset and a “Do everything perfectly” work motto.
