What I'm looking for

I seek senior technical roles where I can lead engineering efforts, build scalable web/Web3 products, mentor teams, and deliver measurable user engagement improvements in collaborative, agile environments.

I am a senior software developer with extensive hands-on experience building full-stack web applications, Web3-integrated game systems, and scalable admin platforms. I lead technical teams, mentor junior engineers, and drive projects from planning through zero-downtime production deployments.

At MXS Games I engineered a Node.js simulation engine and Next.js front end for a Web3 football management game, designed a gamified loyalty program, and executed a flawless migration from Firebase to Supabase while maintaining data integrity. Previously, I led frontend development for MTM Media Monitoring Centre, delivering a high-volume PHP/Symfony email system and an Angular-based service interface with 1,000+ daily unique users.

I blend frontend frameworks (React, Next.js, Angular) with backend technologies (Node.js, PHP, Python) and databases (MySQL, PostgreSQL, Firebase, Supabase) to deliver robust, user-focused products. I prioritize clean architecture, developer productivity, and responsive design while actively engaging with community feedback to iterate quickly.
