At CacheLogic, I migrated a monolithic POS platform to a scalable, multi-tenant microservices architecture, reducing cloud costs while supporting GDPR-compliant data security. I also developed a trading platform supporting 50,000+ daily transactions and improved system reliability by 40%.

At Frizhub, I worked on LegacySuite, a digital estate planning and asset management platform. I developed secure digital vault and legacy-planning features, built responsive interfaces, and contributed to more than 50 RESTful APIs and automation scripts.

Earlier, at Maqware Solutions, I contributed to a secure digital banking platform for a Middle Eastern financial institution. My work spans full-stack development and AI/LLM integrations, with experience across Node.js, Go, Python, React, and cloud-based systems.
