I take AI products and SaaS platforms from "it works on my laptop" to production: LLM and RAG features that give reliable answers, codebases that are audited and cleaned up, and deployments that don't break. Top Rated, with 12 years in software, and one client has rehired me three times. WHERE I HELP MOST • AI that works in production: RAG over your documents, AI agents and LLM integrations (OpenAI, Claude, and Qwen or Llama self-hosted via Ollama) • Full-stack SaaS end to end: multi-tenant architecture, subscription billing, SSO and RBAC, dashboards (Python/FastAPI, Django, React, Next.js, Node.js) • DevOps and deployments: Docker, CI/CD with GitHub Actions, AWS, Google Cloud, DigitalOcean, Nginx • Code audits and rescue work: an independent review of your Python or Next.js code, or taking an AI-generated ("vibe-coded") prototype to production • Tech lead or fractional CTO: architecture, estimates, milestones and Agile delivery RECENT RESULTS ON UPWORK (all 5-star) • DevOps setup and production deployment for a Python API + React CRM on a VPS with CI/CD. This is the client who rehired me three times. • Python backend and Next.js code audits, both delivered ahead of schedule • SSO debugging, a SaaS module deployment ("Perfect, no errors"), a GitHub Actions pipeline and a Python health monitor • React CRACO-to-Vite migration and splitting a large React app into independent modules without breaking production • A self-hosted AI coding platform on Ollama, plus a CRM + time-tracking API sync SELECTED PROJECTS • Aroh360: an all-in-one, multi-module business management SaaS platform • BenchCode: a local-first AI coding platform using open-weight LLMs via Ollama, with SSE streaming, a prompt-enhancement layer and token tracking. Your code never leaves your infrastructure. • AI Translation & Localization SaaS (Laravel + React + FastAPI): multi-tenant, subscription billing, role-based access and automated processing of multiple file formats • Healthcare diagnostics platform suite (Node.js, Laravel, MySQL): patient app, core API, e-commerce and fulfillment BACKGROUND Before founding Advantage AI Engineering, I was a Technical Lead at Ksolves, Project Lead at Hestabit and Lead Solutions Developer at SI-UK, owning architecture, delivery and estimates for startups and enterprise clients. On Upwork, I personally write and review the code on your project. HOW I WORK • A clear scope and milestones before any code • Short written updates, so you always know where things stand • Documented code your team can take over Tell me what you're building and where it's stuck. I'll reply with a practical plan, a timeline and an estimate.
