If you have an MVP that needs to scale or a legacy system that is hitting its limits; You don't need just a developer. You need a Senior Engineer who not only builds the system but owns its technical delivery. I am a Senior Software Engineer with 10+ years of experience engineering high-performance systems.I focus on building systems ready for rapid growth and specialize in complex backends, AI integration, and secure decentralized applications. Technical Stacks: AI-Native Apps: OpenAI/LLMs integration (RAG pipelines, LangChain, fine-tuning). SaaS: React/Next.js frontends with Node.js/Python microservices on AWS (Lambda, Docker, K8s). Web3 & FinTech: Smart contract integration (Solidity) with secure Web2 off-ramps (Stripe/Banking APIs). Proven ROI: -Reduced API latency by 20% via caching and query optimization -Engineered backend systems handling thousands of daily transactions -Rescued failing projects by improving UI rendering speed upto 30%. How I Work: -I don't write a line of code until we have a schema and roadmap planned. -Everything is built with CI/CD, automated testing, and security compliance. -You get direct access to me. No middle managers, no cutting corners and no agency fluff. Client Feedback: "Kamran fixed critical bugs in our MERN app that three previous devs couldn't find... significantly improved stability." "Built our Decentralized Voting Platform from scratch... flawless execution on Ethereum integration."
