I architect and ship production systems end-to-end โ€” from bare-metal private clouds to AI-powered SaaS applications. If it needs to scale, stay online, and actually work in production, that's what I build. Most developers hand you code. I hand you infrastructure, backend, frontend, AI integration, and deployment โ€” all wired together, documented, and ready to grow. Here is what I bring to the table: Private Cloud and HPC Infrastructure I deploy full OpenStack private clouds with complete infrastructure control โ€” no vendor lock-in, no surprise bills. Kubernetes orchestration with auto-scaling and zero-downtime deployments. CI/CD pipelines built with Terraform and Ansible. Monitoring stacks with Prometheus and Grafana so you always know what is happening under the hood. AI-Powered Applications and Conversational AI I build real AI products, not wrappers around ChatGPT. Custom LLM integrations using LangChain and RAG pipelines. Computer vision and NLP solutions with TensorFlow and PyTorch. Python/FastAPI backends designed for speed, connected to PostgreSQL and MongoDB โ€” optimized, indexed, and production-hardened. I also build AI call bots and chatbots that plug directly into your CRM, website, or mobile app โ€” turning conversations into leads, support tickets, or sales without manual effort. Web and Mobile Applications Full-stack web apps with React, Next.js, and Node.js. Cross-platform mobile apps in Flutter with polished UI, Firebase integration, and secure auth. RESTful APIs and microservices architecture that teams can actually maintain. Intelligent Automation n8n and event-driven workflows that connect your entire stack and eliminate manual bottlenecks. I automate what slows you down so your team focuses on what matters. Why clients keep coming back: You get one developer who thinks across every layer. I do not just build features โ€” I build systems where the cloud, the backend, the AI, the chatbots, and the frontend all talk to each other seamlessly. Everything containerized. Everything documented. Everything built to last. Let's talk about your project โ€” message me with the details and I will respond with a clear plan within 24 hours.
