My core expertise sits at the intersection of .NET and C# engineering and modern AI and LLM integration — a combination that lets me ship systems that are both architecturally solid and genuinely intelligent. On the AI side, I've built and deployed real-world applications using Azure OpenAI, Semantic Kernel, and multi-agent orchestration frameworks. This includes a multilingual document translation system for UN field operations handling Arabic, French, English, and Spanish; a RAG chatbot with real-time tool calling over enterprise data; a natural language analytics dashboard querying SQL Server and Cosmos DB; and a 12-agent stock analysis pipeline producing BUY, SELL, or HOLD decisions with entry, target, and stop-loss levels. These aren't demos. They're production systems with measurable business impact. On the backend side, I specialize in ASP.NET Core APIs, Azure Functions, event-driven architectures, and distributed system patterns like SAGA, CQRS, and event sourcing. I've also delivered Azure infrastructure and DevOps projects — multi-region deployments, AKS cluster management, cost optimization, and CI/CD pipelines. I hold a Microsoft Azure Developer Associate certification and work daily with Cosmos DB, SQL Server, Redis, and the broader Azure ecosystem. I also build on the frontend when needed, working with React and Angular, so I can own a feature end to end without handing things off mid-stream. What sets me apart is that I don't just integrate AI as a feature. I architect it as a system. I think in pipelines, agents, retrieval strategies, and evaluation loops. I've worked with ReAct-style agents, agentic RAG, RAGAS evaluation frameworks, and fine-tuning workflows using LoRA, QLoRA, and DPO. I understand the difference between a demo that impresses and a system that holds up in production. I work independently, communicate clearly, and take real ownership of what I build. I'm looking for clients who want serious engineering applied to serious problems — whether that's LLM pipelines, AI-native backends, cloud architecture, or intelligent automation. If you want someone who can think through the architecture, write the code, and ship something that actually works, let's connect. Let's build something worth building. less -

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 -
