Informazioni su questo servizio

Traduzione automatica.

Hai bisogno di uno sviluppatore Node.js affidabile che consegni codice backend pulito, scalabile e puntuale, ogni volta?


COSA COSTRUISCO:

API REST (Node.js, Express, Fastify)

Architettura backend per piattaforme SaaS e dashboard

Design del database (MongoDB, PostgreSQL, MySQL)

Integrazioni di terze parti: Stripe, Shopify, Twilio, Slack, OpenAI

Funzionalità backend alimentate dall'AI e integrazione di agenti

Autenticazione, autorizzazione e accesso basato sui ruoli

Configurazione CI/CD e deployment


PERCHÉ LAVORARE CON ME:

  • Ex Technical Lead, scrivo codice come si aspetta un team senior: pulito, documentato, testato
  • Esperienza diretta nell'integrazione di gateway di pagamento, API AI e servizi di terze parti in sistemi di produzione
  • Comunicazione chiara: saprai sempre lo stato del progetto, senza dover inseguire aggiornamenti
  • Prometto meno e consegno prima del previsto


Che tu abbia bisogno di un'API semplice da zero, di sistemare e ottimizzare un backend esistente o di progettare un backend SaaS completo da zero, definirò chiaramente il scope prima di iniziare così non ci saranno sorprese.


Scrivimi con i dettagli del tuo progetto, di solito rispondo entro poche ore.

    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!
