I’m a Senior Software Engineer with 10+ years of experience building scalable full-stack, SaaS, and AI-powered applications. My core stack includes JavaScript/TypeScript, React, Node.js, Python, PostgreSQL, and AWS, with strong experience designing cloud-native and microservices-based systems. In recent years, I’ve focused heavily on AI-driven platforms and intelligent automation. I recently architected an enterprise AI copilot platform using Python (FastAPI), Node.js, LangChain, Weaviate, and multiple LLM providers. The platform supports conversational AI, RAG-based document retrieval, realtime streaming responses, and voice interaction using speech-to-text and text-to-speech services. I’ve also worked on AI-driven multimedia systems involving voice-enabled AI avatars, realtime conversational interfaces, media upload pipelines, and AI-assisted content workflows. My experience includes practical use of FFmpeg for media compression, streaming optimization, format conversion, and multimedia processing workflows, alongside integrations with OpenAI and ElevenLabs APIs for voice and conversational AI experiences. Previously, I developed AI assistants and automation tools including a LangChain-powered ecommerce support chatbot and a voice-enabled AI assistant using Flask, ChromaDB, and OpenAI. These systems combined LLM reasoning with contextual retrieval pipelines to deliver accurate, production-ready AI interactions. Beyond AI systems, I’ve built and scaled multiple production SaaS platforms across fintech, ecommerce, HR, e-voting, and enterprise operations. Notable projects include FlexiCoop (multi-tenant fintech SaaS), Fivage cloud storage platform, Scavenge ecommerce systems, and cross-platform offline-first POS applications built with Electron. On the infrastructure side, I regularly deploy and scale applications using AWS services including EC2, RDS, S3, CloudFront, Route53, IAM, and CI/CD pipelines through GitHub Actions and AWS Amplify. I also actively leverage AI-assisted development tools such as Cursor, GitHub Copilot, and ChatGPT to accelerate engineering workflows, refactor legacy systems, and rapidly prototype scalable features. Overall, I enjoy building AI-enabled products and scalable systems that bridge intelligent automation with real business workflows while delivering reliable, high-performance user experiences. Currently, I am actively building and scaling AI-powered SaaS systems, enterprise copilots, fintech platforms, and conversational AI workflows involving RAG pipelines, vector databases, voice interaction systems, and cloud-native infrastructure.

I'm a full-stack developer with over 15 years of experience in software engineering. I harness agile methodologies to deliver scalable, robust, and innovative solutions tailored to dynamic project needs. Throughout my career, I've excelled in roles as a Tech Lead and Senior Software Engineer at Flow, and I've contributed to transformative projects at IBM—partnering with clients in banking, retail, and small business. I specialize in turning complex challenges into streamlined, high-impact solutions from design through deployment. Passionate about technology and dedicated to continuous improvement, I’m eager to collaborate with teams and drive projects forward with technical excellence and strategic insight. Let's connect to explore how I can bring value and leadership to your next initiative. I’ve worked with OpenAI’s LLM and IBM’s older Watson platform. My background includes fine-tuning these systems for task-specific needs, integrating them into various applications, and addressing challenges like response latency and knowledge/context management. I’ve also spent considerable effort on prompt engineering to improve accuracy and reduce off-target or “hallucinated” responses from the models. I also have experience using function calling feature to make the AI do more than just work as a Chat box.
