Kasun G.

Expert in AI / ML | Full Stack | Development

I am a Top Rated AI/ML Engineer with a 100% Job Success Score and over 5 years of professional experience delivering production-grade AI systems and full-stack applications for clients worldwide. I have worked with organizations ranging from early-stage startups to large, globally distributed companies, taking full ownership of projects from architecture and development through to deployment and post-delivery support. I graduated as a Computer Engineer and have since built my career on a track record of clean, reliable, and scalable software that performs under real-world conditions. Professionalism is something I take seriously on every engagement. I communicate clearly, set realistic expectations, meet deadlines, and stay available after delivery. When a project wraps up, I do not disappear. If something needs a fix, a new feature, or a refinement down the road, I am reachable and I follow through. Clients across different industries and time zones have trusted me with long-term work because of this approach, and that trust is reflected in my 100% Job Success Score. What Sets Me Apart - Top Rated freelancer with a 100% Job Success Score earned across 5+ years of consistent delivery - End-to-end ownership from architecture and development through to cloud deployment, monitoring, and post-delivery support - Experience working with clients from early-stage startups to large, globally distributed organizations across multiple industries - Strong foundation in both AI/ML engineering and full-stack development, which means I can own the entire system rather than just one layer of it - Clear and honest communication throughout every stage of the project, with structured milestones and regular progress updates - Available after delivery for fixes, extensions, and ongoing improvements What I Can Build For You - Agentic AI systems and multi-agent orchestration using LangGraph, LangChain, and CrewAI - RAG pipelines with hybrid retrieval, vector stores, and LLM evaluation and observability - LLM-powered backends and intelligent API services using FastAPI, Node.js, and Go - Voice AI agents and conversational systems using Twilio, ElevenLabs, and Deepgram - Full-stack AI platforms with React and Next.js frontends and cloud-deployed backends - Mobile applications using Flutter and React Native, covering both iOS and Android. - Cloud infrastructure, CI/CD pipelines, and MLOps workflows on AWS and GCP with Docker and Kubernetes I genuinely enjoy working on challenging problems and building things that make a real difference for the people using them. Thank you for taking the time to visit my profile. I would be excited to learn more about what you are working on and to explore how I can contribute to your project's success.
