Services

What I can build for you

01

Backend Architecture

DDD, CQRS, Event Sourcing, Hexagonal Architecture. Monolith-to-microservices migrations with zero downtime.

How I work

Battle-tested approaches to backend challenges

MPA monolith → SPA + REST API. Symfony + API Platform frontend/backend split. Reverse proxy (Nginx/Traefik) or CORS for separate repos.

SymfonyAPI PlatformReactNext.jsTraefik

DDD bounded context decomposition. Gradual extraction without downtime. Event-driven communication via RabbitMQ/SQS.

WebSockets for real-time features. Redis caching strategies. Aurora MySQL optimization. Load tested to 10K+ concurrent users.

Fast MVPs and codebase modernization for small and mid-size businesses. From greenfield SPA + API builds to full framework migrations — pragmatic decisions that match budget and goals.
