About

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.

AI Enterprise Copilot Platform (Microservices AI System)

Architected an enterprise AI copilot integrating conversational AI, RAG-based retrieval, and voice agents into SaaS workflows. Designed a microservices architecture with a Node.js API gateway and Python FastAPI AI services for orchestration, retrieval pipelines, model routing, and voice processing. Implemented large-context RAG pipelines using Weaviate and integrated OpenAI and Gemini through dynamic routing to optimize latency, cost, and response quality. Enabled realtime AI interactions via WebSockets/SSE with speech-to-text and text-to-speech. Deployed and scaled on AWS using EC2, S3, IAM, RDS, and CI/CD pipelines.

Voice-Enabled RAG Assistant

Developed a conversational AI assistant combining LangChain retrieval pipelines, ChromaDB vector search, and LLM reasoning with voice interaction powered by ElevenLabs. Implemented FFmpeg-based media/audio processing and optimized low-latency voice streaming for realtime AI conversations and multimedia interactions.
Tech: Python, FastAPI, Flask, LangChain, ChromaDB, OpenAI APIs, React

IntelliTest AI Assessment Platform

Lynx
  • Led the architecture and setup of a multi-platform monorepo using LynxJS, PNPM workspaces, TypeScript, Rspack, and shared modules for Web, Android, and iOS builds.
  • Implemented the core build infrastructure, including shell-web, shell-android, and shell-ios scaffolds, Gradle/Xcode configs, and a shared codebase powering all platforms from a single source.
  • Designed and configured cross-platform Tailwind styling, unified environment variable management, and reusable services/hooks across platforms.
  • Built foundational authentication architecture, including axios service layer, token interceptors, global AuthContext provider, secure storage, and error handling patterns.
  • Created a scalable shared src/ framework containing routes, pages, API services, helpers, and UI logic for multi-platform rendering.
  • Integrated Lynx native bridges, device APIs, platform detection logic, and ensured stable metro bundler resolution across shared, Android, and iOS.
  • Collaborated with team members through issue → branch → PR workflow, code reviews, linting setup (Biome), and enforcing scalable engineering standards.
  • Helped establish a long-term development workflow + CI pipeline strategy, focusing on incremental PRs, modular design, team onboarding, and maintainable code practices.
