What I'm looking for

I'm looking to build high-load web products where I can own features end to end, shape maintainable frontend and full-stack architecture, and help junior engineers grow.

At Binotel, I build features across two B2B CRM platforms serving 4,000+ enterprise clients in sales, analytics, and customer support. I own end-to-end delivery across Angular and React codebases, from product requirements and architecture through production release.

I created a reusable component system adopted by five teams, reducing new-feature development time by about 30%, and cut page load times by about 40% through lazy loading, code splitting, bundle optimization, and caching. I also built 15+ data visualizations and real-time dashboards with D3.js and Highcharts for enterprise sales teams.

Across B2B SaaS, iGaming, GovTech, and EdTech, I've delivered scalable interfaces and backend features with TypeScript, Angular, React, Laravel, and Express.js. I enjoy turning complex business requirements into maintainable architecture and mentoring junior engineers into independent contributors.
