What I'm looking for

I’m looking for a team building fintech/enterprise platforms where I can own backend APIs and microservices, improve performance and reliability, modernize legacy systems, and collaborate with Product, QA, Frontend, and DevOps on practical architecture decisions.

I’m a Senior Backend Developer with 6+ years of experience developing fintech and enterprise systems, with strong hands-on work across PHP and Go. I specialize in building reliable, scalable backend services and integrating frontend applications through well-designed REST APIs.

Across my roles, I’ve helped develop and maintain internal CRM systems, financial platforms, and payment gateway integrations. I’ve decomposed monolithic applications into microservices, worked with DDD/SOLID/CQRS and clean/hexagonal architecture approaches, and evolved API contracts to support frontend and backend collaboration.

I’m also focused on engineering fundamentals: optimizing SQL and backend logic for high-load systems, using Redis for caching and RabbitMQ/Kafka for async/event-driven processing, and strengthening stability with unit/integration/acceptance tests using PHPUnit. I enjoy code reviews and architecture discussions with Product, QA, Frontend, and DevOps teams.
