Rickson G.
Senior Full-Stack Engineer & Architect | Python, Elixir, Go, AI
I’m a senior full-stack engineer with 7+ years of experience, focused on backend architecture and AI integrations using Python, Elixir, and TypeScript. Currently studying GoLang. For my Upwork clients, I’ve built products from scratch through launch to paying customers. At Prospect Zero, I owned the architecture, backend, UI, and AI integrations, then led development as the team grew. I’ve also worked on AI inference systems, including usage metering, token tracking, pricing, observability, and agent workflows. I can help you build a SaaS product, integrate LLMs and RAG, improve an existing backend, or architect a complex system, taking ownership from design to deployment.
