What I'm looking for

I’m looking to build scalable, secure, mission-critical web systems where I can own architecture, ship reliably with CI/CD, and grow products end-to-end—connecting technical decisions directly to business outcomes.

I’m a Founding Engineer and Full-Stack expert with 4+ years of experience building mission-critical web applications. I bridge complex technical architecture with business growth, focused on delivering scalable, secure, user-centric software.

At Stellendienst Schweiz AG (SDS Schweiz), I spearheaded the end-to-end development of a Swiss recruitment ecosystem from scratch, owning the full product lifecycle and system architecture. I led and mentored a team of 3 junior developers through code reviews and best practices.

I designed and implemented a high-performance database architecture for data across hundreds of thousands of companies and candidates. I also built mission-critical modules including a high-volume automated mailing engine, dynamic user profiling, and a deep-tier accounting/financial module.

I’ve also strengthened reliability and delivery by establishing CI/CD pipelines and a modular microservices-ready architecture. Previously, I enhanced a WhatsApp-integrated ticketing system with Next.js and MongoDB, and re-engineered a loan settlement frontend in Angular to increase repayments by 1,500/month while securing sensitive financial data.
