My main work is around React Native, Expo, Flutter, Android, iOS, WebRTC, WebAR, Three.js, Firebase, Supabase, push notifications, and Xcode. I enjoy projects that are more than simple CRUD apps, especially live communication, interactive 3D/AR, location-based features, mobile workflows, and apps that need clean backend integration. I can help with building an app from scratch, improving an existing product, fixing mobile build issues, setting up authentication, database logic, storage, notifications, real-time features, and preparing apps for release. I care about clean structure, practical decisions, and writing code that another developer can continue without confusion. For me, a good project is not only about finishing tasks. It is about understanding the product, finding the simplest reliable solution, and delivering something that feels smooth for real users. less -

I specialise in AI-driven software engineering using Python, JavaScript, and AWS, building everything from fast APIs to full end-to-end SaaS platforms. Front-end to back-end, I turn ideas into smooth digital experiences. SQL or NoSQL — I design and optimise databases that run clean and handle real load. APIs & automation — I build scalable REST services and workflow automation that keep products running smoothly. My approach is simple: engineer clean systems, automate the boring parts, and make everything feel seamless in the real world — from the UI to the database to the cloud. Over the past few years, I’ve been working hands-on with AI across practical, production-ready use cases: chatbots, trading bots, analytics tools, talking avatars, object detection, and image generation. My focus is always the same - making AI engine that actually get used, make sense, and deliver value to the product. Whether it’s Python microservices, JavaScript front-ends, AWS cloud architecture, or building a full SaaS system from scratch, I aim for clean engineering and a result that feels remarkable in the real world.

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
