About Samuel

Full Stack Engineer (React/Node/AWS & Cloud) | Building my reputation on Malt


Let’s be direct: I am new to Malt, but I have over 3 years of experience shipping code in the real world.

Because I am building my profile here, I have the most to lose. I cannot afford a bad review or a failed project. This means you get a developer who is hyper-focused on delivering exactly what you pay for—on time and without excuses.

I don’t operate on "passion and motivation"; I operate on professional pride and the necessity of doing a good job to secure the next contract.

What I deliver

  • Scalable Architecture: Experience migrating infrastructure to AWS EC2 to improve uptime and scalability.
  • Performance: I don't just ship features; I optimize them. I have a track record of reducing SQL query times by 40% and cutting Lambda cold starts to <500ms.
  • Full Stack Execution: Expert in React, Node.js, and TypeScript.

If you want a developer who treats your project with the seriousness of a business transaction, let’s talk 🙂.
  • English

    Native or bilingual
