What I'm looking for

I’m looking for a team where I can modernize legacy systems, build scalable backend and real-time solutions, and collaborate with distributed engineers using Agile practices.

I’m a Senior Software Engineer with 8+ years designing and modernizing complex systems across telecom, IoT, and financial platforms. I specialize in scalable backend architectures, legacy modernization, and real-time systems that stay reliable under real-world load.

I’ve contributed to high-traffic platforms and international distributed teams, including IoT infrastructures integrating industrial protocols like BACnet. I work with a strong engineering foundation—SOLID, Clean Code, and Agile (Scrum) habits that keep deliverables improving sprint after sprint.

In recent roles, I developed backend services with Symfony and frontend modules with Angular, including Symfony migration initiatives to improve maintainability and long-term scalability. I also implemented Hexagonal Architecture for IoT core systems, building real-time BMS capabilities with WebSockets and DDD approaches to normalize datasets for scalable streaming and visualization.

Across telecom and compliance projects, I’ve maintained and migrated platforms (including Node.js microservices and deployments on private cloud), built CI/CD pipelines for automated scaling, and optimized performance to support large traffic volumes. In financial intelligence work, I delivered Power BI dashboards and automated FATF report ingestion, reducing manual data entry, and helped build a web-based FORT replacement for an Excel-based workflow.
