Hi, I'm Abbas Raza

Streamlined multi-channel e-commerce operations by developing robust marketplace API integrations, real-time webhook systems, and high-performance synchronization workflows.

• ▹Developed API integrations for Shopify, Shopee, and TikTok marketplaces using Python (Odoo), implementing OAuth flows, bi-directional order synchronization, and product mapping for multi-channel e-commerce operations.
• ▹Redesigned order sync from sequential API calls to bulk fetching with batch database updates, significantly reducing sync time for accounts processing large order volumes.
• ▹Built real-time webhook handlers for TikTok and Shopify with idempotency checks and duplicate prevention, enabling order creation and goods issue generation without polling delays.
• ▹Developed scheduled jobs with checkpoint-based recovery and automatic token refresh, handling order sync, AWB retrieval, shipping updates, and settlement processing across multiple marketplace accounts.

Delivered 20+ diverse, high-impact projects including NFT Marketplaces, B2B/B2C Travel Platforms, SaaS solutions, and ERP systems

• ▹Owned the complete development lifecycle across 20+ client projects, from initial architecture and database design through deployment and production monitoring, delivering across NFT, travel, SaaS, and e-commerce domains.
• ▹Built production applications using React.js, Next.js, Node.js, Laravel, and the MERN stack with MySQL, PostgreSQL, and MongoDB, architecting both monolithic and API-driven systems based on project requirements.
• ▹Designed APIs with comprehensive Postman documentation and integrated payment gateways, flight/hotel booking APIs, and shipping provider APIs into client platforms.
• ▹Developed NFT smart contracts in Solidity (ERC721, ERC721A, ERC4907) covering minting, marketplace listing, auctions, rental functionality, and royalty distribution. Built IPFS metadata systems.
• ▹Set up CI/CD pipelines with GitHub Actions, containerized apps with Docker, deployed on VPS with Nginx/PM2, and managed AWS infrastructure (EC2, Route 53).

Worked remotely with a UK-based health-tech startup building secure data handling systems, NFT metadata infrastructure, and patient-facing React interfaces for a genetic data protection platform.

• ▹Implemented hashing and encryption pipelines for genetic data protection, following security best practices for sensitive personal health information.
• ▹Built an NFT metadata generation system creating unique blockchain-compatible identifiers from user data, ensuring deterministic consistency across minting operations.
• ▹Developed React components with neumorphic design patterns for the patient-facing healthcare dashboard, focusing on accessibility and clear data visualization.
