Full Stack Engineer Specializing in AI-Powered WebCanadaOver the years, I’ve worked across a range of stacks—React, Next.js, Angular, Python (Flask, Django), ASP.NET, Node.js, and Vue—often blending them with cloud platforms like AWS, Azure, and Firebase to deploy robust solutions.

Whether it’s building sleek front-end interfaces or architecting back-end systems that handle thousands of requests per second, I take pride in making products that don’t just function—they perform. By 2022, I was leading full-stack projects using the MERN and MEAN stacks, helping startups launch MVPs in as little as 6 weeks. But I didn’t stop there. As demand grew for smarter, more adaptive systems, I began integrating AI into the products I built. I started with OpenAI’s GPT API, using it to power dynamic customer service bots. Then came automations: workflow engines built using tools like n8n, Make.com, and Zapier that helped businesses cut hours of manual work each week. One project I’m particularly proud of involved building an AI-powered concierge for a travel platform. The bot not only understood user intent from messy input but also remembered returning users, supported multilingual interactions (English + Mandarin), and triggered real-time booking workflows via a custom Node.js backend. What once required human agents was now fully automated—saving the client over 40 hours of support time each week. I’ve also containerized complex systems using Docker and orchestrated multi-service deployments, ensuring they remain stable under load. From crafting admin dashboards with React + Tailwind to deploying .NET APIs on Azure for enterprise clients, I’ve worn many hats—and enjoyed the variety. But beyond the tech, what drives me is problem-solving. Whether it's debugging an edge case at 2 a.m. or streamlining an onboarding flow to reduce churn, I thrive at the intersection of logic and creativity. I don’t just build for today—I build with an eye on what’s next. If you're looking for a developer who can combine engineering precision with creative insight to deliver solutions that are both smart and scalable, I’d love to connect Let’s build what’s next—together My Skills Frontend Development: React, Next.js, Angular, Vue.js, Tailwind CSS, HTML5, CSS3, JavaScript (ES6+), TypeScript Backend Development: Node.js, Express.js, Python (Flask, Django), ASP.NET Core, PHP Full-Stack Frameworks: MERN Stack, MEAN Stack Cloud Platforms & Deployment: AWS (EC2, S3, Lambda), Microsoft Azure, Firebase API Development & Integration: REST, GraphQL, third-party API integrations AI & Automation: OpenAI GPT API, n8n, Make.com, Zapier, custom workflow automation Databases: MySQL, PostgreSQL, MongoDB, Firebase Firestore DevOps & CI/CD: Docker, Docker Compose, container orchestration, GitHub Actions, Azure DevOps less -

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 -
