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 -

Whether it's streamlining operations, improving customer experiences, or integrating AI into existing workflows, I enjoy finding practical ways to use technology to solve real business challenges. My approach is simple: understand the business goals first, then build solutions that are scalable, maintainable, and designed for long-term success. Clients often appreciate that I communicate clearly, take ownership of my work, and remain focused on delivering results rather than just completing tasks. On the technical side, I specialize in modern full-stack development using React, Next.js, Node.js, TypeScript, and Python. I also work extensively with AI technologies, including LLM integrations, AI agents, workflow automation, chatbots, and API-driven solutions that help businesses operate more efficiently.

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 -

We're a full-stack engineering team working U.S. business hours. 10+ years building software, 500+ companies served. Same timezone, same Slack channel, same engineers from kickoff to delivery. Right now, most of our work involves helping companies integrate AI into their products and workflows, build custom LLM applications, develop intelligent chatbots trained on their own data, deploying automation agents that replace manual processes, and building data pipelines that extract and classify information at scale. Not API wrappers, production-ready systems that hold up. But AI isn't all we do. We're a complete development team: → Full-stack web & mobile: React/Next.js, Node, Python, .NET Core, React Native, Flutter. One team, no mid-project handoffs. → WordPress & CMS: custom themes, ACF/Gutenberg blocks, WooCommerce, migrations, performance optimization. → UI/UX redesign: better user experience without rewriting your codebase. → Cloud & DevOps: AWS, Azure, GCP: we build it, deploy it, and keep it running. → QA from day one: testing is part of every sprint, not a last-minute pass. What makes us different: you won't wait until tomorrow for a response. We work your hours, we iterate in real time on Slack, and the cost advantage comes from where our engineers are based, not from cutting corners. Whether you need a smart assistant integrated into your platform or a reliable team to build and ship your project, message us. We'll give you an honest read on fit, timeline, and cost. less -

It is a system that solves a real problem, fits into the user’s workflow, and works reliably when people actually depend on it. My background is a little different from the typical developer path. I have an M.S. in Neuroscience, hands-on experience with AI and machine learning, and a strong focus on building practical tools that solve real problems. That mix has shaped the way i work: I like understanding the problem deeply first, then building something clean, useful, and dependable around it. My work is especially strong in AI-powered applications, healthcare technology, speech-to-text systems, data workflows, and Python-based software. One of my main projects, VoxChart, is a clinical desktop dictation application built with offline Whisper AI speech recognition, SQLite medical terminology correction, autosave, crash reporting, Epic EHR export, and a Windows installer pipeline. I have also built computational neuroscience tools using Python, Keras, TensorFlow, OpenSim, and reinforcement learning, including a DDPG-based spinal cord arm model developed from my graduate research. Clients usually do not need someone who only writes code. They need someone who can understand the goal, think through the edge cases, build cleanly, communicate clearly, and deliver software that feels dependable. What I can help with: - Full-stack web application development with React, Next.js, Node.js, Express.js, JavaScript, TypeScript, PHP, Laravel, Java, Spring Boot, and Python - Custom dashboards, admin panels, client portals, and SaaS platforms - REST API development, third-party API integrations, and backend automation - Database design and development with SQL, SQLite, PostgreSQL, MySQL, MongoDB, and Supabase - Business workflow automation and internal productivity tools - WordPress, PHP, and custom CMS-based website development - Cloud deployment, hosting setup, Docker workflows, and performance optimization - Speech-to-text systems, Whisper AI integration, and AI-assisted workflows - Healthcare AI, clinical workflow tools, and research automation - Data processing, scientific computing, testing, debugging, documentation, and long-term maintenance ✔ What clients should feel when the work is done: “He understood the product, not just the task.” “I didn’t have to explain the same thing five times.” “He took a messy idea and turned it into something we could actually use.” When there is a real problem to solve, whether it is a full-stack web app, a SaaS platform, a custom dashboard, an automation workflow, or an AI-powered tool, the goal is always the same: build something useful, stable, and practical enough for real people to depend on. The best software starts with a clear conversation, gets built with honest decisions, and ends with something people can actually depend on. Let's get started! less -
