Nuwan F.

Need a software product built, modernised or taken to the next stage? I help businesses solve complex technical problems through software development, SaaS engineering, AI implementation and automation. My focus is not simply writing code. I help work out what should be built, how it should be architected, and the most practical way to turn the business requirement into reliable, production-ready software. I CAN HELP WITH: ✓ SaaS and web application development ✓ AI features, agents and integrations ✓ Workflow and business process automation ✓ MVP and new product development ✓ Legacy software modernisation ✓ Architecture and scalability ✓ Technical debt reduction ✓ APIs and complex integrations ✓ Security and reliability improvements ✓ Cloud infrastructure and DevOps SELECTED PROJECT EXPERIENCE: → Modernised a digital lending platform following security issues and downtime, resulting in 100% uptime post-migration. → Led the engineering of payment gateway and settlement infrastructure that achieved a 3x increase in IPG margins and 100% uptime. → Led the modernisation of an enterprise SaaS platform affected by technical debt and multi-tenancy issues, including the implementation of AI-enabled workflows. I’m comfortable working across both existing products and new builds. EXISTING SOFTWARE If you already have software, I can help identify what is holding it back and determine the right approach to modernise, scale or extend it. NEW PRODUCTS If you’re building something new, I can help translate a well-defined business problem into the product scope, architecture and development roadmap needed to bring it to life. TECHNICAL EXPERIENCE React, Next.js, Flutter, NestJS, Python, FastAPI, Go, .NET/C#, Rust, PostgreSQL, MongoDB, Firebase, Supabase, Redis, Kubernetes, vector databases and RAG pipelines. Cloud architecture and production deployments across AWS, Azure, GCP and IBM Cloud. For larger or more complex projects, I have a team of highly skilled engineering resources ready as required. If you have a software product that needs improving, a manual process you want to automate, an AI capability you want to implement, or a new product you want to build, send me a message and tell me what you’re working on. I’ll help you work out the most practical technical path forward.
