🚀 Senior Full-Stack & AI/ML Engineer | Building Scalable, Intelligent Web Applications You don’t just need code, you need a reliable, production-ready product that scales, performs, and leverages the true power of modern AI. With over 10 years of experience, I specialise in bridging 𝒄𝒖𝒕𝒕𝒊𝒏𝒈-𝒆𝒅𝒈𝒆 𝑨𝑰 𝒊𝒏𝒏𝒐𝒗𝒂𝒕𝒊𝒐𝒏 𝒘𝒊𝒕𝒉 𝒔𝒕𝒓𝒊𝒄𝒕 𝒆𝒏𝒈𝒊𝒏𝒆𝒆𝒓𝒊𝒏𝒈 𝒅𝒊𝒔𝒄𝒊𝒑𝒍𝒊𝒏𝒆. I partner with SaaS founders, enterprise teams, and ambitious startups to transform complex ideas into high-performing digital realities that drive real business results, not just fragile prototypes. ⚡ What I Bring to Your Project 🤖 𝐀𝐫𝐭𝐢𝐟𝐢𝐜𝐢𝐚𝐥 𝐈𝐧𝐭𝐞𝐥𝐥𝐢𝐠𝐞𝐧𝐜𝐞 & 𝐌𝐚𝐜𝐡𝐢𝐧𝐞 𝐋𝐞𝐚𝐫𝐧𝐢𝐧𝐠 * **Generative AI:** ChatGPT / OpenAI API integration, LLM fine-tuning, and custom AI copilots. * **Intelligent Automation:** Autonomous agents, AI workflows, and sophisticated chatbot ecosystems. * **Advanced Analytics:** Predictive modeling, recommender systems, NLP, and computer vision. 💻 𝐅𝐮𝐥𝐥-𝐒𝐭𝐚𝐜𝐤 & 𝐌𝐨𝐛𝐢𝐥𝐞 𝐀𝐫𝐜𝐡𝐢𝐭𝐞𝐜𝐭𝐮𝐫𝐞 * **Robust Backends:** Node.js, Next.js, Django, Flask, REST APIs, GraphQL, and microservices. * **Dynamic Frontends:** Modern, responsive UI/UX using React, Tailwind CSS, and contemporary JS frameworks (MERN/MEAN stack expert). * **Cross-Platform Mobile:** Seamless, native-feeling applications built with **Flutter**. ☁️ 𝐂𝐥𝐨𝐮𝐝 𝐈𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞 & 𝐃𝐞𝐯𝐎𝐩𝐬 * **Cloud Platforms:** AWS, GCP, Azure. * **Continuous Delivery:** CI/CD pipelines, Docker, Kubernetes. * **Scalable Databases:** High-performance system design and optimization across SQL, NoSQL, and Firebase. 💡 The "𝐖𝐡𝐲 𝐌𝐞?" Factor Many developers can build an AI wrapper, but few know how to architect the scalable, secure, and maintainable infrastructure required to support it in the wild. I don't just write scripts; I build resilient systems designed for real-world user loads and long-term growth. If you are building a next-generation SaaS product, integrating AI into an existing platform, or looking to intelligently scale your current architecture, let’s collaborate. 📩 𝗦𝗲𝗻𝗱 𝗺𝗲 𝗮 𝗺𝗲𝘀𝘀𝗮𝗴𝗲, 𝗮𝗻𝗱 𝗹𝗲𝘁’𝘀 𝗱𝗶𝘀𝗰𝘂𝘀𝘀 𝗵𝗼𝘄 𝘄𝗲 𝗰𝗮𝗻 𝗯𝘂𝗶𝗹𝗱 𝗮 𝗳𝘂𝘁𝘂𝗿𝗲-𝗿𝗲𝗮𝗱𝘆 𝘀𝗼𝗹𝘂𝘁𝗶𝗼𝗻 𝘁𝗵𝗮𝘁 𝘀𝗲𝘁𝘀 𝘆𝗼𝘂𝗿 𝗯𝘂𝘀𝗶𝗻𝗲𝘀𝘀 𝗮𝗽𝗮𝗿𝘁.

You have an idea that combines a real web product with AI, and you need a developer who treats the AI part as core infrastructure, not a bolt-on at the end. Most full-stack developers can build the app. A smaller group can build the AI pipeline. Very few can do both and think through where those two worlds collide in production. That is the gap I fill. For the past 6 years, I have been shipping full-stack web products with AI automations and third-party integrations designed in from day one. Real products with paying users, not side projects. 𝗔 𝗳𝗲𝘄 𝘁𝗵𝗶𝗻𝗴𝘀 𝗜 𝗵𝗮𝘃𝗲 𝗯𝘂𝗶𝗹𝘁 𝗿𝗲𝗰𝗲𝗻𝘁𝗹𝘆: An AI-driven SaaS platform that automates marketing campaigns end to end, scaled to $15K+ MRR across 50+ agencies A three-portal fintech platform with Stripe Connect, webhook-driven state machines, and ACH compliance handling, with $6M in loans approved through the platform and another $20M in progress A data pipeline processing 2M+ daily records from BigQuery and SFTP sources A cross-chain Web3 platform supporting Ethereum and Solana with real-time marketplace updates 𝗪𝗵𝗮𝘁 𝘆𝗼𝘂 𝗴𝗲𝘁 𝘄𝗵𝗲𝗻 𝘆𝗼𝘂 𝗵𝗶𝗿𝗲 𝗺𝗲: A developer who reads your brief carefully and asks the right questions before writing any code Full-stack ownership across React, Next.js, and Tailwind on the frontend and Python, FastAPI, Django, and Node.js on the backend AI integration done right, using OpenAI, Anthropic, LangChain, and agent orchestration patterns that hold up in production Third-party API work without silent failures, including Stripe Connect, Meta Marketing API, and webhook-driven systems Cloud infrastructure on AWS and GCP with Docker, CI/CD, and proper monitoring baked in Clear communication and predictable delivery, no disappearing mid-sprint The clients I work best with are founders and teams who care about shipping something that actually works, not just something that demos well. You know what you want to build. You need someone who can take the idea, translate it into a system, and carry it to production without needing their hand held. If that sounds like a fit, click the green "Invite to Job" button at the top of this profile. Tell me what you are building, and I will come back with a few sharp questions so we can figure out fast if this is the right match.

Enterprise teams hire me when the React codebase needs to be architected right from the start or rescued from years of shortcuts. I have led frontend teams, built annotation systems for medical imaging from scratch, and delivered two Upwork contracts over $40K each with 5-star reviews. $80K+ earned on Upwork, 100% JSS, Top Rated Plus. What I've built: - Digital Pathology Slide Viewer: Technical Lead on a medical imaging platform for pathologists. Architected the entire annotation system from scratch using OpenSeadragon, including custom polygon clipping algorithms, real-time collaborative annotations via Websockets for concurrent users, and virtualized rendering handling hundreds of annotations simultaneously without performance degradation.

I’ve helped my clients launch and improve products used by thousands of users, reduce load times by 30-50%, and deliver features that directly supported revenue-generating flows. I work primarily with React, Next.js, TypeScript, and modern CSS, building production-ready interfaces that are fast, reliable, and easy to maintain. I’m comfortable working across the full stack when needed, connecting frontend logic with APIs, databases, and real-world product workflows. Alongside that, I have a strong interest in Web3 and blockchain systems. I’ve worked with wallet integrations, smart contract interactions, and dApp frontends, and I actively follow developments around EVM, L2 solutions, and scaling technologies. For me, Web3 is not separate -- it’s an extension of building solid, real-world applications. I value clear communication, ownership, and thoughtful implementation. If you’re building something meaningful and need a developer who thinks beyond just code -- let's have a chat.
