About
Ten years ago, I started my journey as a backend developer who simply enjoyed solving hard problems. Over time, I realized I wasn’t just writing code; I was building the foundations that businesses depend on every day.Today, I work as a Lead Software Engineer, helping companies turn complex ideas into reliable, scalable systems. I have worked in FinTech, HealthTech, ERP, and trading platforms, building systems that handle real-time data, financial transactions, production lines, and sensitive healthcare information.One of the things I enjoy most is transforming messy, slow monolithic systems into clean, event-driven microservices. In one case, this reduced feature delivery time from one month to one week. In another project, we improved ERP response times by 35% during peak hours. I believe good architecture is not just about technology; it is about helping teams move faster with confidence.Leadership became a natural part of my growth. I have led cross-functional teams of up to 12 engineers, mentored junior developers, and worked closely with executives to translate business goals into technical strategy. I care about building a culture where quality matters more than speed and where knowledge is shared instead of siloed.I also have experience with international standards such as GDPR, FHIR, and IATF 16949. For me, compliance is not a checklist; it is part of building trustworthy systems.Technically, I work mainly with TypeScript, Node.js, NestJS, distributed systems, real-time messaging, and cloud infrastructure. But beyond tools, I focus on clarity, clean architecture, and long-term reliability.My background in digital image processing and mathematics shaped the way I think: structured, analytical, and detail-oriented. I like systems that are precise, predictable, and built to scale.I am always interested in challenging projects where technology directly impacts business growth. If you are building something ambitious and need strong technical foundations, I would be happy to connect.
