Projects

  • AI-Powered Automation for Large-Scale Research

    Cloud AI Data Automation

    2024-Present

    Technologies Used: Jupyter Lab, Qdrant Vector Database, Kubernetes, GCP, AWS, PubMed, LangGraph, AI Agent SDK and APIs from OpenAI, Anthropic, Gemini (Google Cloud), Puppeteer, FastAPI, React, etc.

    I'm a Tech Lead and Solution Architect for multiple projects at Delineate Inc., a Y-Combinator funded company. I supervise and collaborate with a team of talented engineers to build AI-powered automation systems for large-scale research and data analysis. These systems are especially utilized by the world's leading pharmaceutical and biotech companies and organizations. I ensure that the systems are designed and built to be scalable, fault-tolerant, and secure, while leveraging the latest advancements in AI and cloud computing.

  • Real-time Air Ticket & Hotel Booking System

    Software Suite GDS/API

    2018-2024

    Technologies Used: Web Scraping, Node.js, Rust, MySQL, Redis, Docker, Laravel, React.js, React Native, Expo, AWS, Cloudflare, Payment Gateways, and more.

    I'm the lead developer and architect of this project. I had the opportunity to work with a lot of talented developers and engineers from around the world, both onsite and remotely to build this system from scratch to a scalable and secure system that users can trust and rely on.

  • AI-integrated E-commerce Platform

    Dialogflow ML Multilingual NLP

    2016

    Technologies Used: Dialogflow ML (previously API.ai) - Dataset Preparation & Training, Custom multilingual (Bn-En transliteration) NLP, Node.js, WooCommerce, Facebook Messenger Bot API, Wit.ai and more.

    Technically I was the sole developer of this project with two other business partners while I was studying at university. I had a lot of fun building it. This was one of the first ML-based AI integrated e-commerce platforms in the world (with both English & Bangla NLP), alongside eBay (English) in 2016.

  • Decentralized Digital Asset Inheritance

    Peer-to-Peer Network

    2020-Ongoing R&D

    Technologies in R&D: C to Web Assembly, Blockchain RPC from Bitcoin, Ethereum (L1 & L2), Solana, NEAR, and more. Federated Time Oracle PoC done in Nest.js.

    This project can provide each user a "digital will" for their future generations. The basic idea is combine Shamir's Secret Sharing scheme with a federated (or eventually decentralized consensus-based) time oracle to create a decentralized digital asset inheritance system in user-friendly apps.
