Over the last 9+ years I’ve built and operated secure, production‑grade backends, AI features, and DevOps pipelines for SaaS products, higher‑education, and enterprises. What I can do for you ✅ Build "Chat with your Data" & RAG Systems • Internal "ask anything" assistants over knowledge bases, handbooks, logs, tickets • RAG pipelines with robust retrieval, access control, and evaluations • OpenAI & Claude integrations (chat, embeddings, tools/agents), including Azure OpenAI • Modern dev tooling: Cursor, Claude Artifacts, MCP servers for reliable tool‑use ✅ Design & Implement Reliable Backends • Python APIs and microservices (FastAPI / Django REST / Flask) behind your AI features • Clean, testable architecture and documentation your team can maintain • SQL/NoSQL data models, caching (Redis), background jobs, webhooks ✅ Automate Workflows & Operations • AI‑driven workflows that reduce manual review and ticket triage • Integrations between your app and third‑party tools (CRMs, email, marketing, data platforms) • Scheduled jobs, alerting, and reporting dashboards ✅ DevOps & Cloud Infrastructure • Docker & Kubernetes deployments, CI/CD pipelines • Infrastructure as Code, observability (logging, metrics, tracing) • Secure, scalable setups on AWS/Azure (networking, secrets, backups) 🏆Why clients hired me ✅Business‑first, not model‑first. Every AI feature and backend change is tied to a clear goal: faster workflows, fewer errors, or better insight from your data. ✅Production mindset.

I keep you updated with short, non‑technical status summaries and propose options with trade‑offs so you can decide quickly. ✅End‑to‑end ownership. From initial architecture and POCs through deployment, monitoring, and hand‑over documentation. 🧑💻Next steps If you need an engineer to design, build, or stabilize AI‑driven backends, RAG apps, or internal automation, send me a short message about: 1. What your system does today? 2. what you want it to do and what do you want to build? 3. ETA I’ll reply with an honest assessment of fit and a concrete next step (quick call, architecture sketch, or small paid discovery task). less -
