Hire the Best TypeScript Developers
in Belgium

I help startups and small companies turn ideas into working products: fast. Whether it's an MVP, a SaaS tool, or a B2B integration, I build reliable, production-ready apps using React, Node.js, Python, and Java. My background is in enterprise fintech. For the past 6+ years I've built financial messaging systems that handle high-volume transactions the kind of software where reliability isn't optional. I bring that same engineering discipline to smaller, faster moving projects. What I can help you with: → MVPs and web apps (React + Node.js, Python, Java (Spring or Quarkus) backends) → SaaS products and internal B2B tools → API development and third-party integrations → AI-assisted development : I use Claude daily in an enterprise setting and know how to leverage AI to ship faster while catching the mistakes it makes. → Cloud deployment on AWS or GCP (certified in both) I also built my own product : MapCanvas.store an e-commerce platform that's been used to generate over 40,000 maps across 35 countries. I designed, built, and launched it independently, so I understand the full picture from idea to live product. Tech I work with: Java, Spring Boot, Python, React, Node.js, PostgreSQL, Docker, Kubernetes, AWS, GCP. If you have a project you need built properly and quickly, send me a message and I am happy to discuss scope and see if it's a good fit.

I’m a full stack engineer with 10+ years of experience building production applications with React, Next.js, TypeScript, and modern backend systems. Clients usually bring me in when they need more than basic implementation: rebuilding legacy platforms, improving frontend performance, solving complex application issues, integrating AI features, or turning rough ideas and designs into polished products. Recent work includes rebuilding the Knipklok platform into a modern SSR React/Next.js application, improving performance, SEO, reliability, translation handling, caching, and complex booking flows. I’ve also built AI integrations for production applications, Web3 tooling, NFT systems with on-chain utility, Chrome extensions, and scalable frontend architectures. Projects I’ve worked on include: · A Chrome extension for the Pixels Web3 game used by 50,000+ users with 2,000+ paying subscribers · The B Side NFT collection and mutable NFT systems on Injective · Production React/Next.js platforms with SSR, SEO optimization, caching, localization, and complex API integrations My day-to-day stack includes React, Next.js, TypeScript, Node.js, Supabase, Firebase, Svelte, Astro, Flutter, AI integrations, Solidity, WebGL/Three.js, and CI/CD workflows. I communicate clearly, work independently, and take ownership from architecture to delivery.

I help startups and enterprises turn complex product ideas into stable, scalable SaaS, AI-powered web apps, and mobile products — with clean architecture, reliable delivery, and no unnecessary technical debt. I’m a senior software engineer with 12+ years of experience specializing in full-stack solutions . I help teams build, scale, modernize, and optimize high-performance applications with a strong focus on maintainability, reliability, and real business outcomes. I work across JavaScript/TypeScript and Python, using React, Angular, Node.js/NestJS, FastAPI, PostgreSQL, OpenAI, RAG pipelines, and AI agent workflows. I’ve delivered products across B2B platforms, FinTech, MedTech, CRM systems, accounting/invoicing software, SaaS dashboards, and hybrid mobile apps using technologies like React, Angular, Vue, Node.js, NestJS, React Native, Ionic, MongoDB, and PostgreSQL. My current focus is helping businesses integrate AI-powered features into real products — including AI apps, automation workflows, RAG-based systems, AI agents, document intelligence, analytics assistants, and conversational interfaces. I use AI-assisted development where it adds speed, but all architecture, product, and production decisions stay human-driven, tested, and maintainable. I’m strongest when the project needs more than just coding: understanding the business logic, designing the right architecture, reducing technical risk, and shipping a product that can grow after launch. I can help with: * SaaS MVP development * AI-powered web applications * RAG and document intelligence systems * AI agents and automation workflows * Dashboards, admin panels, and internal tools * API integrations and third-party systems * Codebase refactoring and performance optimization * Hybrid mobile apps with React Native or Ionic If you need a senior engineer who can move fast without creating a mess, I’d be happy to help turn your idea or existing codebase into a reliable product.

Senior Full-Stack Engineer and System Architect with 8+ years shipping fast, reliable web platforms in TypeScript, Node.js, and React. I turn messy requirements into production systems that scale and stay up. Most of my work lives where frontend, backend, and infrastructure meet, so I can own a feature end to end instead of handing it off three times. A few things I've delivered: Cut core transaction latency by 82.5% (400ms down to 70ms) while holding 99.9% availability at 3,000+ requests per minute Designed multi-tenant AWS microservices with Terraform, backed by CI/CD quality gates and 90%+ test coverage Built a fault-tolerant payment engine on PayU APIs, using LocalStack mocking to eliminate environment drift Delivered real-time React/D3.js interfaces for 30,000 to 50,000 concurrent users, plus PostgreSQL tuning across 1M+ records Hardened auth and sessions with opaque cookie frameworks and email-based 2FA to close session-hijacking and enumeration gaps How I work: I think about your business, not just the ticket. I ask what a feature is actually for, flag the risky parts early, and scope an MVP that ships instead of stalling. Tech I use daily: Frontend: React, Next.js, Vue, Angular, GraphQL Backend: Node.js, Express, Python Data: PostgreSQL, MySQL, Redis, DynamoDB Cloud and Infra: AWS (Lambda, S3, API Gateway, DynamoDB), Terraform, Docker, LocalStack I work best with founders and product teams who want a senior developer they can hand a problem to and trust to deliver. Send me a note about your project and I'll tell you honestly how I'd approach it.
