Experience

Product engineer at Midlane

Nov '23 - Jun '25
TypeScriptNext.jsReactSQLAWSLambdaQueueEventsDDDArchitectureSecurityLeadershipProduct

Built HR technology for the underserved blue-collar market at this early-stage startup.

Working closely with our small team, I contributed to foundational product decisions and technical architecture. We delivered focused features rapidly while maintaining quality standards, helping the company iterate toward product-market fit in a demanding, fast-changing environment. The primary problematics were datapoint collection, document generation, and employee onboarding funnels.

Lead engineer at Klarna

Jul '23 - Oct '23

Led engineering efforts in the Card & Banking domain, focusing on improving user experience across mobile and web platforms of the Klarna app. I focused on shipping a new documents delivery mechanism for bank users.

Though my time was brief, I made the difficult decision to leave for an exceptional opportunity that better aligned with my goals.

Staff engineer at Passbase

Aug '19 - Jun '23
GoRubyRailsSQLTypeScriptReactNext.jsWebpackStyled-ComponentsAWSTerraformDDDArchitectureLeadershipManagementHiringSecurity

Grew with this VC-backed identity verification startup from early-stage through successful acquisition.

Initially built frontend foundations for 3 core applications, then evolved into hiring and leading our growing frontend team. When we achieved product-market fit, I contributed to architecting our next-generation platform using domain-driven design principles—working across frontend, backend, and infrastructure.

Software engineer at Recare

Jun. '18 - Mar. '20
TypeScriptJavaScriptFlowReactReduxGraphQLRESTWebpackBabelE2E Encryption

Developed secure healthcare software for patient transfer services across German clinics.

Working with sensitive patient data required zero-trust architecture—I maintained and improved our end-to-end encryption system ensuring complete data privacy. When I identified maintainability issues in our legacy codebase, our team executed a complete Flow-to-TypeScript migration, using comprehensive end-to-end tests to ensure reliability throughout the transition.

For international expansion into France, I built a dedicated internationalization management app from scratch, enabling synchronized translations across our entire product suite and streamlining our localization workflow.

Frontend developer (intern) at Mhirba

Apr. '17 - Aug. '17
JavaScriptFlowReactAngularVueElectronIoTPrototyping

Prototyped IoT interfaces for enterprise clients at this specialized craft studio.

I evaluated and implemented frontend solutions across multiple frameworks (React, Angular, Vue) for cross-platform applications. The rapid prototyping environment taught me to balance technical exploration with practical client feedback loops—skills.

Game developer (intern) at Wolcen

Sep. '15 - Dec. '15
C++ActionScript 2.0CryEngine 3Entity-Component-SystemDocumentation

Contributed to game development at this indie studio during their first major release cycle.

I implemented game menus, improved dependency management, and worked on shader compilation systems. With the team preparing to scale, I created detailed technical documentation.


Education

Master's Degree at Epitech

Sep. '14 - Aug. '19
CC++JavaSQLTDDArchitectureManagement

Epitech’s hands-on curriculum empowered me to develop practical skills from the start, fostering independence through its self-learning approach. I honed my ability to write clean, maintainable code and thrive under tight deadlines, both individually and within teams. My coursework explored fundamental and advanced topics in software engineering, including low-level programming (C and C++) and software architecture.


Projects

Molecule

JavaScriptFlowReactCSSStyled-ComponentsWebpackBabel

Solely designed and implemented a robust and refined web platform for an e-sports agency. This project illustrated the importance of aligning technical solutions with business goals, as close collaboration with non-technical stakeholders was integral to its success. Aside from the technical perspective, it offered me end-to-end exposure to delivering and hosting polished software in real-world conditions.
