Backend Developer — PHP, Laravel & REST APIs
I build and maintain the backend systems, admin dashboards and APIs that other people's apps run on. Over 4+ years I've shipped production platforms in Laravel, CodeIgniter and MySQL for corporate, e-learning and service businesses — including the APIs behind live mobile apps.
the shape of most days: apps and dashboards talking through APIs into a database
Backend-first, comfortable across the whole stack
I'm a PHP developer based in Delhi, working mainly in Laravel and CodeIgniter with MySQL underneath. Most of my work sits on the backend — admin dashboards, database design, and REST APIs that power mobile apps and third-party integrations — but I also build the front-end features around them with JavaScript, jQuery and React when a project needs it.
I care about writing code that's still easy to work with a year later: SOLID principles, sensible design patterns, and structures that don't fight the next developer who opens the file. I've picked up AWS (S3, Rekognition) along the way and work comfortably in Agile teams using Git and ClickUp.
