Product Engineer, Input
May 2025 - November 2025 • Amsterdam, Netherlands
I'm part of a small Sequoia-backed team building the next generation of email and collaboration tools. I work across the entire product surface, from shaping features to shipping them into production.
My day-to-day spans building a native-feeling macOS desktop app with Electron, developing fullstack AI agents, and building a local-first data layer using PGLite and ElectricSQL. In spirit of the company we own features from idea to launch, working across frontend, backend, and infrastructure to improve performance, reliability, and overall UX.

Software Engineer, Zühlke Group
October 2022 - May 2025 • Frankfurt, Germany
At Zühlke, I worked across a variety of client projects in FinTech, eCommerce and HealthTech, contributing to both frontend and backend systems in complex enterprise environments.
I helped deliver production systems across 5+ projects, built backend services handling over 200,000 requests per day, and supported new client acquisitions through technical research and solution design. Along the way, I also played an active role in growing the internal blockchain community through training sessions and knowledge sharing.

Founding Engineer, Soulbonds.xyz
October 2021 - October 2022 • The Web 3.0
I co-founded and built a decentralised reputation platform focused on on-chain identity and trust. In a two-person team, I engineered a scalable web application from the ground up, supporting over 1,000 concurrent users at launch.
The project generated over $100,000 in revenue and secured comparable external funding, and I led technical integrations and partnerships with two major ecosystem players.

Research Intern, Jetbrains
June 2020 - January 2021 • Remote
As part of JetBrains Research, I explored how novel data sources could improve code reviewer recommendation systems.
The work resulted in a measurable improvement of over 3% in recommendation precision and was carried forward into a distinction-graded Master’s thesis, as well as a published conference preprint.
