What I'm looking for

I'm looking to own scalable applications across the full development lifecycle, solve complex production issues, improve engineering practices, and contribute through technical decisions, code reviews, and mentoring.

I've built and supported scalable PHP, React, and JavaScript applications across Triple Aceforward, OSG, Evolutics Technology, and Cognizant.

At Triple Aceforward, I led 20+ product features and 40+ REST API and system integrations, increasing user engagement by 15% and improving integration efficiency by 18%. I improved application performance by 20% through database optimization, caching, asynchronous processing, and backend tuning.

At OSG, I maintained 99% production uptime across APIs, application services, databases, and AWS infrastructure. I also optimized PostgreSQL, MongoDB, and Redis access patterns while improving CI/CD, automated testing, monitoring, and incident resolution.

I enjoy owning software through production support, designing reusable services, improving delivery workflows, and helping engineers make sound decisions through code reviews, debugging, and mentoring.
