What I'm looking for

I’m seeking senior/lead full-stack or founding-engineer roles in Europe or Canada—where I can build production-grade SaaS, optimize performance, and own end-to-end delivery with a strong engineering culture.

I’m a Full Stack Developer and SaaS founder with 5+ years building production-grade platforms across blockchain, e-commerce, health-tech, and logistics. I focus on shipping end-to-end products with clean architecture, strong performance, and reliable delivery.

At ARTMO, I improved performance by 60% (800 ms → 320 ms) and built the Masterclass feature that enabled €30K+ in platform revenue across 10,000+ artists. At Mirai Tech Solutions, I shipped 4 client products end-to-end and optimized CI/CD pipelines (GitHub Actions + Docker), cutting release cycle by 30% while reducing deployment errors.

Recently, I founded Trackili.tn, an AI-powered CRM with 10 paying merchants. I integrated Gemini AI for near-zero manual order entry, built bi-directional Shopify webhook sync, and delivered geographic analytics—while owning product roadmap, full architecture, all code, and infrastructure.
