Blockchain Expert | Data Wizard | Full-Stack Developer

I decode blockchain data and build full-stack analytics systems that turn on-chain activity into business insights—helping Web3 teams track performance, predict user behavior, and make data-driven decisions.

📄 My CV | 📊 Dune Portfolio – #1 Analyst on Cardano, Plasma & Ronin blockchains

On-chain Analytics & Data Engineering

• Automated ETL pipelines processing millions of blockchain transactions
• Real-time dashboards for DeFi, gaming, NFTs, and L1/L2 ecosystems
• ML models for user behavior, retention prediction, and anomaly detection

Full-Stack Applications

• Production APIs and web apps (FastAPI + Next.js + Dune Analytics)
• Interactive dashboards processing live blockchain data
• End-to-end analytics platforms with intelligent caching (Singleflight Merger) and real-time updates
• Cross-platform mobile applications with Defense-in-Depth IAP Sync (iOS/Android/Telegram), utilizing StoreKit 2 appAccountToken to eliminate payment race conditions.
• Industrial Ingestion Clusters: Developed a multithreaded Stealth Archiver (Playwright) on Contabo VPS using human heuristics and High-Res Image Hijacking to deliver 4K visuals from low-res embeds.
• Distributed CI/CD Architecture: Built a "Zero-Exposure" deployment pipeline using GitHub Actions that handles Secret Reconstitution (ephemeral decoding of production certificates) for automated native builds.
