About Belkacem

Senior Full-Stack - I transform your ideas into reliable, fast, and scalable products

Launching a product, an MVP, or need to strengthen your tech team?
I can assist you as an outsourced CTO + senior full-stack developer, to help you move faster, avoid costly mistakes, and lay down technical foundations capable of scaling.

Results I deliver:
  • A robust MVP, architected, designed to evolve.
  • A clean, secure, and scalable stack from the start.
  • Clear visibility: roadmap, organization...
  • Controlled costs thanks to optimized architecture.
  • Smooth execution: CI/CD, monitoring, automation.
In short: you gain speed, peace of mind, and productivity.

My approach (which makes the difference)

Not just code, I combine product vision, startup experience, engineering rigor, and CTO-level diligence to secure your choices.
Do you speak business? I translate it into viable technical solutions, designed for the long term, then I develop, optimize, structure, and deliver.

My areas of expertise
  • Full-stack development: NestJS, Typescript, React, Next.JS, Python.
  • Cloud & Infrastructure: AWS, Serverless.
  • Pipeline & Monitoring: GitLab CI, Grafana, Metabase.
