I’m a senior software engineer who specializes in backend architecture, scaling systems, and solving critical infrastructure problems end to end. I enjoy taking ambiguous problems and turning them into reliable, production-ready solutions—whether that means designing database schemas, shaping API integration strategies, or building robust data pipelines that eliminate real-world sync and consistency risks. I’ve led technical delivery across EU-scale projects and also operated autonomously during a major scaling window, shipping features with incomplete inputs while maintaining high engineering quality. I build and grow teams too—scaling from one engineer to multiple contributors with clear review standards, onboarding, and pairing—while using modern tooling and AI-assisted development to accelerate delivery.

Work Experience

Senior Software Developer (Contractor) at solve-x
June 1, 2025 - January 31, 2026
Owned full-stack product delivery during a critical scaling period with minimal support. Maintained and shipped features solo for ~5 months from incomplete requirements (Figma only), taking autonomous architectural decisions including schema design and API integration strategy. Built a reliable data layer for unreliable third-party APIs using dual-write architecture to mirror and version-control critical data, eliminating sync failures and providing complete transaction history. Scaled the engineering team from 1 to 6 engineers by creating onboarding and pairing sessions so new hires could contribute within 2 weeks. Accelerated delivery using AI-assisted workflows (Claude, Ollama) for log parsing, code generation, and documentation, and built CI/CD and local automation scripts to reduce onboarding friction.
Senior Software Developer at Rendstad Belgium
January 1, 2022 - January 1, 2025
Led technical strategy and delivery across three EU Commission projects (CPP, EWSI, EJTP) using PHP/Drupal 10. Managed scope, gathered requirements directly from clients, and presented weekly demos to stakeholders. Scaled the team from a solo developer to three engineers by establishing code review standards, documentation practices, and technical decision-making frameworks. Built an automated data aggregation pipeline that removed about 10 hours of weekly manual work and improved consistency across project templates. Authored technical documentation and provided hands-on support to non-technical stakeholders, translating complex requirements into implementation roadmaps.
