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 focus on reliability, observability, and security from day one, so your system can stand up to real usage, not just demos. ✅Clear communication. 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 -

I have practical experience in developing full stack applications and leveraging AI to solve real world problems. I am an expert in Python, FastAPI, Django, React, Node.js, PostgreSQL, MongoDB, AWS, Docker and current AI/ML tools. I have hands-on experience with building LLM powered applications, RAG systems, vector databases, computer vision, automation workflows, API development, and cloud deployment to the cloud. I am adept at building full-stack SaaS solutions, developing AI chatbots and AI agents, creating insightful data analysis and dashboards, integrating ML models, design and building backend architecture and APIs, as well as deployment to cloud platforms such as AWS. Instead of just building proof-of-concepts, I focus on clean architecture, stable backend and reliable API for my applications, and useful user-facing features to empower users and enhance the overall user experience. I'm particularly interested in AI automation, Generative AI applications, computer vision and building data-driven platforms, workflow tools and SaaS products. I enjoy taking on complex technical challenges, optimizing existing solutions, and transforming early-stage ideas into robust, production-ready software. If you need an individual who can integrate AI seamlessly into your full-stack products and domain-specific ML projects, I'd be thrilled to collaborate with you. less -
