I'm Saaim Abdullah, a software engineer based in Lahore. I build complete software products for businesses: premium, fast, mobile-first websites and web apps designed around what your business actually needs to do, whether that's booking more calls, taking payments, or closing sales. No recycled templates and no cut corners.
Under the hood, that's real engineering. Over the past two years I've shipped production systems for companies across Europe and beyond: high-end frontends, REST APIs and backend services, event-driven ETL and data pipelines (Kafka, Spark, Airflow), AI features such as RAG chatbots and recommender systems, and full AWS cloud infrastructure (Lambda, EC2, ECS, S3, RDS, Redshift). When a project needs real logic, integrations, dashboards, or data behind it, I build the whole thing end to end, from the landing page to the database.
My flagship project is Fitter Health A preventive health-tech platform I built entirely from scratch and took all the way to production for a Spain-based team, owning the frontend, backend, cloud, and data layer. I also share how I build these systems on Medium and take on select client work through Upwork.
"He frequently delivered ahead of scope and raised considerations we had not thought to ask about."
