About me

I design, build, and operate backend systems across financial services, e-commerce, and consumer products. I've worked on systems serving 100M+ monthly active users, with experience spanning APIs, data processing, integrations, and production operations.

My approach to software architecture focuses on clear domain boundaries, maintainable services, and reliable data flows. I work with concepts from domain-driven design, event-driven architecture, and hexagonal architecture, applying patterns where they help manage complexity.

What I work on

APIs & Architecture

REST APIs, domain modeling, service boundaries, and designing backend services around complex business requirements.

Async Systems & Reliability

Redis, queues, background workers, event-driven processing, retries, and idempotent operations.

Data & Performance

MySQL, database optimization, indexing, caching, Elasticsearch, MongoDB, and investigating production bottlenecks.

Integrations & Delivery

Payment providers, third-party APIs, webhooks, automated testing, Docker, CI/CD, and cloud deployment.

Technology stack

Languages & Frameworks

PHP Laravel Symfony

Databases & Search

MySQL Redis Elasticsearch MongoDB

Infrastructure & Delivery

Docker GitHub Actions

Open source

I contribute fixes and tests to open-source projects in the PHP ecosystem and build small tools for practical backend problems.
