What I'm looking for

I’m looking for remote work where I can lead backend architecture end-to-end, integrate AI features safely in production, and improve reliability and performance with measurable impact—while collaborating closely with product owners across time zones.

I’m a Senior Backend Engineer with 8+ years building production systems for US clients, fully remote. I’m available for remote contracts via Deel, Remote.com, or Oyster, and I focus on shipping reliable backend services that perform under real-world load.

My proudest milestone is scaling a telemedicine platform to 500,000+ users while maintaining 99.9% uptime across consultation, messaging, and prescription workflows. I integrated OpenAI and Claude APIs into patient-facing workflows using structured validation, retries, and fallbacks to prevent bad outputs from reaching users.

I’ve also served as a working tech lead for 4 years, managing a team of 6 while staying the primary technical contributor. At Infonaligy Partners, I helped modernize an enterprise insurance platform from a PHP monolith to Node.js/MongoDB microservices—boosting scalability by 60% and cutting infrastructure costs by 40%—and re-architected payments to reduce completion time from 20 minutes to under 2 minutes.

These days, I’m senior IC-focused and excited to keep building AI-powered products that work safely and reliably in production. I bring a strong engineering core in Node.js/TypeScript, PostgreSQL, AWS, and system design—paired with a practical, results-driven mindset.
