What I'm looking for

I’m looking for a role where I can own backend architecture and performance, build real-time and secure webhook systems, and apply AI-powered search/automation to solve real product problems—while collaborating closely and mentoring developers.

I’m a Senior Backend Engineer with 3+ years of experience designing and optimizing high-performance backend systems. I build scalable communication platforms, engineer low-latency real-time architectures (WebSockets/Laravel Reverb), and focus on database optimization, system performance, and secure webhook processing.

Across my roles, I’ve architected unified backends for large iOS ecosystems using Twilio, implemented fraud detection and reputation scoring, and improved API response speed by 40% through SQL optimization, caching, and N+1 query fixes. I also develop AI-powered search systems with Solr plus LLM/vector and image search, and automate workflows across social platforms (Instagram/Facebook/TikTok/Telegram) while maintaining strong code quality and security practices like OAuth 2.0, JWT authentication, signature verification, and rate limiting.
