Hi! I'm Mali, a Senior Software Engineer with health tech experience and a background in Behavioral Neuroscience and Psychology. Technical Expertise: Frontend: Next.js, React, TypeScript Backend: Node.js, Go, RESTful APIs, FHIR Database: PostgreSQL, Redis, ClickHouse Cloud & DevOps: GCP, AWS, Kubernetes, Vercel Recent work: Founding Engineer at an AI-powered e-commerce search startup: built core infrastructure, merchant dashboard, and multimodal search system alongside the CTO Healthcare startup (4-person team): built e-prescribing integration, medication sync pipelines, and FHIR-compliant endpoints I'm excited to return to health tech. Let's discuss how I can help your team!

I build product software, not just screens. I’m a senior full-stack product engineer with 6+ years of experience shipping SaaS platforms, creator tools, dashboards, automation workflows, and e-commerce systems for remote teams across Europe, the US, and Morocco. My strongest value is taking messy product requirements, understanding the system behind them, and turning them into clean, maintainable software. I work mostly with TypeScript, React, Vue/Nuxt, Python/FastAPI, Node.js, PostgreSQL, Supabase, Firebase, Docker, and Cloudflare. The framework matters less than the fundamentals: data flow, product constraints, API design, UX quality, performance, reliability, and the tradeoffs that keep a product easy to evolve. Relevant work: - Senior developer work on a YouTube creator SaaS with React, FastAPI, MySQL, ClickHouse, Qdrant, and Redis. - Built a 60+ component design system and complex onboarding flows for a private membership platform. - Helped expand a creator/social automation platform from Twitter-only to TikTok, Threads, and Facebook. - Built an AI-assisted contract parser that extracts structured data from PDFs. - Led Vue/Nuxt e-commerce rebuilds backed by Java Spring Boot and PostgreSQL for Moroccan beverage brands. - Shipped internal tools, dashboards, admin panels, CI/CD, Docker deployments, and production support workflows. I’m a good fit when you need someone who can reason through the product, challenge weak assumptions, review architecture, and still ship quickly. I’m especially useful for SaaS builds, AI-assisted workflows, creator tools, dashboards, technical rescue/refactor work, and full-stack product features that need senior judgment. GMT+1, available for focused milestones or longer-term product work.

I am a software engineer with experience in backed development , big data, data scraping, AWS, GCP, web3Js, react, system design.
