Hi, I'm Rahul and I specialize in building AI-driven systems and strategically leveraging tools like GPT-4, Azure Cognitive Services, and Copilot to accelerate delivery without compromising on quality or scalability.
I’m a Full Stack Product Specialist, and I bring 18+ years of experience building scalable systems that bridge engineering excellence with business outcomes. I focus on AI-infused architecture—applying tools like Azure Cognitive Services, natural language rule engines, and GPT-based co-pilots to accelerate delivery and unlock intelligent workflows.
From IoT platforms and fintech systems to behavior-driven mobile apps, I work at the intersection of tech architecture, team leadership, and practical AI integration.
Key Contributions-
• Designed an AI-enhanced youth platform: Used Azure Cognitive Services, Python scripting, and a natural language rule engine to personalize user nudges based on behavior signals.
• Built Flutter + Firebase IoT apps integrated with Alexa/Google for smart appliance control—leveraging voice interfaces, MQTT messaging, and geo-aware triggers.
• Architected nationwide POS and billing systems deployed at Walmart/Sears for Fiserv—integrated with payment processors like Chase, PayPal, and BOA.
• Delivered a video collaboration platform for a US startup with a serverless backend (Node.js, AWS Lambda, Python)—supporting async media and real-time events.
Technical Toolbox
• Server Frameworks- Node.js, Microsoft Technology Stack: Web API (REST), Entity Framework, ASP.NET MVC and ASP.NET Core using Code First and Database
• Client-Side JS Frameworks- React JS, JavaScript, Angular 2+, Vue JS, Flutter, jQuery, Bootstrap
• Client-Side UI Frameworks- HTML 5, CSS 3, Bootstrap
• Databases- Azure SQL, SQL Server, MySQL, MongoDB, PostgreSQL, Cosmos DB, Google Firebase Firestore
• Cloud Services-AWS, Azure, GCP, Firebase
🤝 Why Clients Work With Me
• 100 % ownership of product outcomes
• AI-aware delivery with intelligent automation
If you want to turn your product idea into a cloud-ready, AI-augmented platform, I’m just a message away.
