My approach is simple: I build custom websites that not only look great but are also engineered for peak performance and global reach. Unlike standard templates, every project is a bespoke solution, leveraging Python, HTML & CSS, and TypeScript to deliver fast, secure, and responsive experiences across all devices and browsers. My focus on performance optimization and localization ensures your site is ready to grow with your business, providing a seamless experience for every user, no matter where they are.

I’m a Software Engineer with a passion for building impactful products in the financial markets. I thrive on solving complex technical challenges — whether it’s integrating with global banks, designing real-time systems for FX trading, or leading full-stack projects from architecture to deployment.

Currently at Kooltra, I’m helping banks, asset managers, corporations, and active traders stay ahead in the foreign exchange market by delivering scalable, modern financial technology. From building trading microservices and real-time rate streaming to migrating CI/CD infrastructure and leading localization efforts, I focus on delivering high-performance, production-ready systems that make a difference.

🛠️ Core skills: Kotlin, Java, Python, React, Go, Django, GitHub Actions, AWS, CI/CD, microservices, Salesforce integration, optimization algorithms, financial APIs, system monitoring (Sentry), full-stack web development.
