Build or extend your SaaS product

Extend your SaaS without rebuilding it.

Most products don’t need a rewrite. They need someone who can add the next feature, upgrade the parts that have aged and keep deploys boring. I work across Rails and Node.js backends, React and Angular frontends, and the AWS infrastructure underneath.

You work directly with me, Muhammad Haroon: a software engineer with 5+ years of shipping products with teams in the US, UK and Pakistan.

What I can take on

Subscription and plan gating for paid features
REST APIs and third-party integrations, such as HubSpot and Stripe
Redis caching for slow, frequently read data
In-place upgrades of legacy Rails codebases while the product stays live
Docker deployments, AWS EC2 and CI/CD pipelines
Editing workflows so non-developers can manage content
