Open-source Backend Solutions Development
I'm a backend engineer who thrives where software meets hardware—designing high‑performance systems, real‑time data flows, and scalable architectures that solve complex, real‑world problems. With over a decade of experience across FinTech, IoT, data‑processing, and custom platform development, I build solutions that are fast, reliable, and thoughtfully engineered.
I'm passionate about Redis, C#, PHP/Symfony, and modern DevOps practices, and I love turning ambitious ideas into production‑ready systems. Beyond engineering, I share my fascination with technology as a content creator, making innovation accessible to a wider audience.
Above all, I'm driven by curiosity, craftsmanship, and the belief that great software should make a measurable impact.
Open-source Projects
A Symfony Messenger transport integration for NATS JetStream, enabling reliable asynchronous messaging with persistent message streaming.
Tool which allows to passthrough messages fetched from RabbitMQ's queue to NATS PubSub. Useful if you receive a data feed through RabbitMQ, but you need to redistribute it further to multiple clients in the most efficient way.
