What I'm looking for

Senior Software Engineer seeking fully remote roles in AI, backend, or full-stack engineering. I enjoy building scalable production systems with Python, TypeScript/Node.js, React, cloud platforms, APIs, LLMs, RAG, and agentic AI. I’m looking for a high-ownership, product-focused team where I can own projects end-to-end and solve meaningful technical problems.

At Ingenix.ai, I lead architecture and development of production AI applications and backend services. I’ve designed RAG systems that combine LLMs, embeddings, vector retrieval, and contextual knowledge retrieval.

I’ve developed agentic workflows with LangChain and LangGraph, including tool calling, multi-step reasoning, and human-in-the-loop processes. I’ve also built enterprise knowledge assistants and multi-agent architectures that connect AI agents with business tools and internal services.

As Founding Engineer at Innovatech Systems Technology, I led end-to-end development of web, mobile, and AI-powered applications, from early product design through production deployment. I built backend APIs and developed web and mobile applications with React.js, React Native, and Flutter.

Earlier, at Addepto, TechNova, and Alltegrio, I developed enterprise and full-stack applications, REST APIs, data workflows, and production integrations. My work has included machine learning integrations, performance improvements, and applications built with Python, Node.js, C#/.NET, and modern frontend frameworks.
