Description

Looking for a Fullstack Tech Lead to drive your product from A to Z? A developer capable of scoping, architecting, and delivering with complete autonomy?

I am a Fullstack Tech Lead with 7 years of experience in B2B SaaS products and complex business applications.

I have worked for high-impact clients:

Monabee (solar energy platform, 6,000+ users)

Medsoins Santé (network of 15+ medical centers, 350+ daily users)

Argentic Music (mobile game for artist Sadek)

Wanteez By H&L (ERP for coordinating thousands of agents)

I will support you from A to Z:

Product scoping, specs, and technical architecture

Backend: Node.js, NestJS, Fastify, TypeScript

Frontend: Next.js, React, Angular, Nuxt

Mobile: Flutter

Data & infrastructure: PostgreSQL, Prisma, Supabase, Redis, Docker, Linux

Payment & integrations: Stripe

AI integration: LLM APIs (Anthropic, OpenAI), chatbots, prompt-based content generation

Agile project management, freelance supervision

Also comfortable with existing stacks: Laravel, Ionic

Want to connect AI to your product without breaking what exists? I delivered a chatbot in production at Monabee, and I am developing CRAFLO (SaaS for managing CRA and invoices for freelancers) with a prompt-based quote generator via the Anthropic API.

Shall we discuss your project? Contact me directly on the platform.
