Description

Fighters Unbound is a Web3 project merging real-life physical training with dynamic on-chain NFT evolution. Activity tracking is powered by Strava, with the fighters currently live on Mintify x Shape_L2 and updates planned around daily tasks, consistency, and LLM-based trainers.

My Role

As the full stack developer, I implemented:

  • Full responsive frontend including minting dashboard, Strava sync panel, live NFT evolution viewer, user profile with activity-to-trait mapping
  • Scalable backend services handling API orchestration, webhook ingestion from Strava, AI agent execution, and on-chain transaction queuing
  • End-to-end data pipeline from raw Strava JSON → vector embeddings → AI decisioning → on-chain metadata updates
  • Reduced database query load by 70% through intelligent vector caching, embedding reuse, and query optimization in ChromaDB
  • launched and maintained the entire platform in production, supporting live activity-driven NFT progression for the full 5,200-piece collection with zero downtime during mint phase.
