HASNAIN SHAHEEN

I'm a software engineer and founder with 12+ years of experience shipping production software for international clients and remote teams. I don't just write code, I take products from idea to launch and keep them stable after.

What I build:
• Backend systems and REST APIs (PHP, Node/TypeScript, SQL)
• Web apps (React, Next.js, WordPress custom development)
• Cross-platform and native mobile apps (Flutter/Dart, Swift/iOS)
• AI/LLM integrations (chatbots, automation, document workflows)
• Performance, security and reliability improvements for existing codebases
• Technical audits and architecture reviews

Why work with me:
• Hands-on founder of a field-service app for UK gas engineers (jobs, certificates, invoices), so I understand real product constraints, not just tickets
• Comfortable as both individual contributor and technical lead
• Practical, production-first approach: clean architecture, clear communication, no unnecessary complexity
• Experience working with clients and teams across time zones

How I work:
• Clear scope and milestones upfront
• Regular updates, no disappearing acts
• Code that's documented and maintainable by your team after handoff

Send me a short brief of what you're building (or what's broken) and I'll reply with an honest assessment, a realistic timeline and the fastest path to launch.
