What I'm looking for

I’m looking for a role where I can build products that make a meaningful difference, work with a supportive and curious team, and continually learn and grow.

I want to contribute my experience while expanding into new challenges that push me to become better in my career.

I’ve led engineering execution for platforms serving up to 400,000 monthly active users and scaled Android TV deployments to over 500,000 active devices.

I’m comfortable owning systems end-to-end, from infrastructure and APIs to frontend platforms and deployment pipelines.

My achievements include:

• Led technical strategy and engineering execution for a consumer platform serving approximately 400,000 monthly active users across web, mobile, APIs, and wallet infrastructure

• Scaled the TeachBuddy Android TV platform to 500,000+ active devices while maintaining a sub-2% crash rate through offline-first synchronization and reliability improvements

• Architected and delivered a unified monorepo platform (Next.js + React Native) supporting OTT streaming across web, mobile, and Android TV environments

• Introduced CI/CD automation pipelines that improved release reliability and reduced cross-platform deployment effort across engineering teams

• Coordinated six active third-party infrastructure and compliance integrations while maintaining delivery velocity across distributed engineering teams

• Designed and implemented wallet infrastructure and upgradeable smart contracts using OpenZeppelin UUPS architecture within a live production platform

• Built and launched Hiitown, a community discovery and events platform supporting 5,000+ users, 100+ events, and multiple service providers across Europe

• Delivered merchant-facing CMS and checkout interface improvements at Cashew Payments that supported measurable improvements in checkout conversion performance

• Implemented test automation workflows and release confidence improvements across frontend engineering pipelines

• Led frontend delivery of enterprise-grade asset tracking platform Atlas V1 while introducing TDD workflows that improved system stability

• Delivered data visualization and geospatial operational interfaces for a Dutch energy-sector client using Mapbox and DeckGL

• Designed Shopify-integrated delivery orchestration infrastructure aggregating multiple logistics providers into a unified fulfillment workflow (Trippa)

• Built a Social Rewards Protocol on Algorand using OpenAI-based content quality scoring and token-based engagement incentives (Aura Engine)

• Directed architecture for a real estate CRM and listings platform supporting agencies and end customers (Wealthview Real Estate)

• Built and deployed multi-tenant partner applications using Turborepo and pnpm workspaces, enabling reusable infrastructure across multiple branded product environments
