About this gig

Your app isnt doing what it should? Data wont save, payments fail, or nothing connects properly? Founders, devs, and business owners all run into these backend headaches that slow everything down.


I'm Haris full-stack developer who builds solid backend systems, connects things that dont talk, and fixes bugs others leave behind. I work with Node.js, Express, MongoDB, MySQL, Prisma, Socket.IO, Magento 2, Laravel, PHP, and Python.


Heres how I can help:


Develop custom REST APIs

Secure CRUD, auth/0auth, OTP, roles, file upload, real-time system any custom api


Integrate third-party APIs

Stripe, Notion, OpenAI, TikTok, Instagram, Facebook, Google, Zapier, GHL, crypto APIs, content moderation, location services


Backend logic

Secure API calls (Axios, fetch, OpenAI SDK), JWT/OAuth flows, webhook listeners, CRON jobs, email/SMTP, file import/export, data formatting


Frontend connection

Trigger API calls on click/submit, show loading/errors/success, display results (chats, tables, forms) in your UI


Fix backend issues

Broken endpoints, CORS, deployment bugs, database errors, middleware failures


Let's get your backend working the way it should. Message me now, I'll make it right.
