About
Since starting my career in 2014, I have grown into a software architect who designs high-performance systems and a team lead who brings technical direction to engineering teams. I combine deep expertise across the .NET, Node.js and PHP ecosystems with modern architectural approaches to turn complex business requirements into scalable, reliable and maintainable products.
I design and deliver microservice architectures and event-driven systems for high-traffic, mission-critical projects — particularly e-commerce platforms and payment systems. Beyond code quality, I focus on the system as a whole: choosing the right database, building search and indexing infrastructure, and putting fast caching layers in the right places.
As a team lead, my priorities are keeping the Agile/Scrum culture alive, setting quality standards through code review, and helping every engineer on the team reach their potential. I take ownership across the full software lifecycle, building systems that improve operational efficiency and add direct value to the business.
What I do
Where I take ownership — from architectural decisions to team culture.
Translating business requirements into scalable, reliable and maintainable system designs.
Building platforms that scale through independently deployable services with clear boundaries.
Designing asynchronous, resilient and loosely coupled communication flows on Kafka and RabbitMQ.
Layered architecture, CQRS and design patterns for testable, maintainable codebases.
Sustaining Agile/Scrum culture and actively planning the technical growth of each engineer.
Setting quality standards through code review and improving performance by measuring bottlenecks.
