Marcin Szulc
Summary
👤
SeniorMarcin Szulc is a Technical Lead with 10 years of experience building and migrating payment and payout platforms, currently driving engineering at Volt.io from Krakow. He has deep Java/Spring expertise born out of leading a major migration from PHP monoliths to microservices at Azimo and Papaya Global, and routinely bridges code-level detail with infrastructure conversations. Known for reading documentation and source code end-to-end, he pairs hands-on implementation—Grafana dashboards, partner API integrations, Android performance tweaks—with architecture and product design. He thrives in high-pressure, business-critical deliveries and has stepped into lead roles repeatedly as teams scaled. Actively learning Go, he’s looking for opportunities to apply his backend and systems mindset to new cloud-native challenges.
