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 -

Throughout my career, I've worked on projects ranging from SaaS platforms and e-commerce systems to AI-powered applications and complex business automation workflows. One thing I've consistently found is that successful software isn't just about writing code—it's about understanding the problem behind the project and building solutions that make a real impact. I've helped founders launch products from scratch, modernized legacy systems that were slowing down business growth, and developed automation solutions that saved teams countless hours of repetitive work every week. 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.
