Real artists ship.

8 years. 50+ products. 3 companies. From full-stack JavaScript platforms to AI agents, intelligent automation, and responsible AI integration — I architect production systems that are secure, auditable, and built to scale.
Services
AI Integration & Intelligent Automation
AI agents, RAG pipelines, intelligent workflow automation, and responsible AI implementation. I review your operations, identify where AI creates real leverage, and build secure, auditable systems into your stack — not black-box demos.
Full-Stack Product Development
End-to-end application development. JavaScript, TypeScript, React, Node, Python, cloud-native architectures. From database schema to deployment pipeline. 50+ products shipped.
Technical Consulting & Strategy
Architecture reviews, technology selection, due diligence for investors, and hands-on guidance for teams scaling up. I've built and run my own products — I understand the business side.

About
Software engineer. 8 years of shipping software. 50+ products. 3 companies running.
I've spent my career thinking in systems — decomposing complex problems into clean architecture and shipping engineered solutions that hold up in production. I started building full-stack platforms in JavaScript and TypeScript, scaled that into SprintX, and built two SaaS products: CrossCheck and Callis.io (AI agent receptionist).
I also work with business owners to integrate AI into their operations — agents, intelligent automation, RAG systems — with a focus on responsible, secure, and auditable implementation. Not demos. Production systems with real governance.
Testimonials
Don't take my word for it.
"Hassan did a phenomenal job throughout the development process. He was very professional, knowledgeable, timely, and communicative — keeping us updated on progress, flagging issues before they became problems, and suggesting solutions that saved us both time and money. We cannot recommend him enough."
"Hassan and the team at SprintX have been absolutely fantastic. Their professionalism, integrity, and drive has enabled us to develop our product at speed and with excellent results. They work in a very structured way and delivery is great. Their contributions to our product have been invaluable."
"Hassan is the best. His work is amazing. He is honest and direct. He hits his timelines. Very good at working from Figma. I really enjoyed the fact he is willing to give his opinion and tell me when he thinks something could be improved on. I cannot say enough good stuff about him!"
