Don't Just Take My Word For It
A 5.0 rating across every engagement. Here's what happens when clients hand me a hard problem.
“I had the absolute pleasure of working with Zain on a project that went from being a complete disaster to an absolute masterpiece. Their exceptional skills, attention to detail, and deep understanding of the subject matter truly made all the difference. They didn't just patch up the obvious problems they dug deep into the code, making sure every line was optimized and efficient. The final result was nothing short of amazing. The code was clean, well-documented, and highly maintainable. The user experience improved drastically. The project was not just fixed it was elevated to a whole new level. If you're facing a project that seems insurmountable, Zain is who you want on your side.”

Technical Expertise
8+ years of hands-on experience across the full backend stack, data engineering, and cloud infrastructure.
What I Can Build For You
Whether you need a new backend, a data pipeline, or a full product I bring the technical depth to make it production-ready.
Backend Development
Scalable server-side systems built with Node.js and Python. Microservices, monoliths, event-driven architectures designed for performance, reliability, and long-term maintainability.
API Design & Integration
REST and GraphQL APIs built for speed and clarity. From public-facing APIs to complex third-party integrations I design contracts that are intuitive for consumers and solid under load.
Cloud Infrastructure
End-to-end cloud architecture on AWS compute, storage, serverless, and networking. CI/CD pipelines, auto-scaling, and infrastructure-as-code for reliable, cost-efficient production systems.
AI & Big Data Pipelines
High-throughput data pipelines for real-time and batch workloads using Kafka and Airflow. Computer vision models and ML inference endpoints integrated into production backend services.
Blockchain Development
Smart contract integration and blockchain explorer tooling. I've built middleware layers connecting web apps to Ethereum-based chains and processed on-chain data at scale.
Full-Stack Web Applications
Complete web applications with React and Next.js frontends backed by robust APIs. From MVP to production auth systems, dashboards, admin panels, and real-time features.
