What I'm looking for

I want to lead backend architecture for scalable microservices, modernize legacy systems, and mentor teams—building high-performance, API-driven products on AWS while owning delivery from requirements to production.

I’m a Backend Architect and Technical Manager with 15+ years of experience building and scaling backend systems for both service-based projects and product-driven platforms. I bring deep expertise in PHP and modern backend technologies like Node.js, Python, MySQL/MongoDB, Redis, Docker, and RESTful APIs, with a strong focus on system architecture, performance optimization, and third-party API integrations.

In my recent roles, I’ve led teams end-to-end—mentoring and managing high-impact engineering groups (20 members and 10 members), advising on legacy modernization, and delivering backend solutions across ecommerce, logistics, travel, and education. From designing distributed systems and scalable microservices to handling technical debt and cost optimization, I consistently align engineering execution with business outcomes while keeping delivery reliable and measurable.
