I build PHP backend systems for payments, compliance, healthcare, and SaaS platforms.

What I'm looking for

I'm looking to build and improve production backend systems where I can solve complex workflow, integration, performance, and legacy-modernization challenges with cross-functional teams.

I'm currently delivering backend features for Elligint Health's business-critical healthcare platform, improving stability across legacy Symfony/Yii1 services, SQL workflows, background processes, and client integrations.

At Rokolabs, I built Laravel features for a compliance workflow platform used by investment firms and wealth managers. I improved database performance by 20–30%, reduced response times by about 30% with Redis caching and queueing, and strengthened release safety through PHPUnit coverage and legacy refactoring.

At Microbiz.com, I integrated NMI and BlockChyp payment gateways, reducing manual payment work by 40%, while building microservices and REST APIs for payments and order processing.

Earlier at WeMakeFab, I built a CRM from scratch, delivered Laravel/Symfony web applications, and introduced TDD and automated testing that reduced post-release bugs by 40%. I enjoy translating business requirements into maintainable technical solutions alongside Product, QA, frontend, and DevOps teams.
