Maksymilian Dudek

I’m a Senior Backend Engineer with 9+ years of experience architecting, developing, and scaling high-performance, distributed systems. I focus on designing robust microservices and RESTful APIs while keeping solutions secure, scalable, and maintainable.

At Tooploox, I architected and led a scalable microservices platform using .NET Core, Golang, and NestJS, supporting 20k+ MAU. I implemented Kafka-based event-driven architecture processing 350K+ events/day, and built real-time services with Socket.IO and WebSockets handling 4K+ concurrent connections.

I drive performance and reliability improvements across the stack—reducing API latency from ~300ms to 120ms using query optimization, Redis caching, and async processing. I also led monolith-to-microservices migration, cutting deployment time by 60%, and improved PostgreSQL and MongoDB query performance by 35%, backed by Dockerized CI/CD pipelines for reliable releases.

Previously at SoftwareHut and Monterail, I built enterprise backend systems with Spring Boot and Laravel (PHP), designed REST APIs (99.9% uptime), and implemented RabbitMQ-based asynchronous processing and JWT/OAuth2 authentication. I enjoy mentoring engineers, collaborating cross-functionally, and applying clean architecture and system design best practices in fast-paced Agile teams.
