Over deze dienst

Automatische vertaling

Ben je op zoek naar een betrouwbare Node.js ontwikkelaar die elke keer op tijd schone, schaalbare backend code levert?


WAT IK bouw:

REST API's (Node.js, Express, Fastify)

Backend architectuur voor SaaS-platforms en dashboards

Database ontwerp (MongoDB, PostgreSQL, MySQL)

Integraties met derden: Stripe, Shopify, Twilio, Slack, OpenAI

AI-gestuurde backend functies en agent integraties

Authenticatie, autorisatie en rolgebaseerde toegang

CI/CD setup en deployment


WAAROM MET mij werken:

  • Voormalig Technical Lead ik schrijf code zoals senior teams het verwachten: schoon, gedocumenteerd, getest
  • Directe ervaring met het integreren van payment gateways, AI APIs en third-party services in productie systemen
  • Duidelijke communicatie je weet altijd de projectstatus, geen achtervolging voor updates
  • Ik onderbelicht de tijdlijnen en lever eerder dan gepland


Of je nu een eenvoudige API vanaf nul wilt bouwen, een bestaande backend wilt laten repareren en optimaliseren, of een volledige SaaS backend vanaf de grond wilt ontwerpen, ik maak het duidelijk voordat we beginnen zodat er geen verrassingen zijn.


Stuur me een bericht met je projectdetails, ik reageer meestal binnen een paar uur.

    Amazing developer! Really goes the extra mile for us and ensures we are delighted with the work. We ran into a few unexpected roadblocks on this project, but they were solved without much trouble or discussion. I can't say enough positive things. Highly recommended!

    Very good experience. On this project, part of it was deciphering another developers work so we had to work closely to navigate the labyrinth of someone else's decisions. We were able to successfully retrieve and re-organize some important data that was stored and organized in a complex and unusual way....

    Very good! This was a successful collaboration as it always is. In this project we had a few extra things that came up during development and the developer was able to take care of them as they came up. We did our QA testing on the new project and found no bugs at all! Good communication! Thorough testing!

    This was a really great experience. The developer took care of everything quickly and expertly. We even had one thing come up during development that did not occur to us originally. The developer took care of this for us too. A+ Communication and Collaboration skills, it makes it easy to discuss the work the specifics of the job. Perfect work!
