Designed and implemented a Python-based ETL pipeline for web scraping, data normalization, and entity relationship mapping, processing structured football data (players, clubs, leagues, and agencies) to ensure data integrity and consistency.Architected and deployed cloud infrastructure on Google Cloud Platform (GCP), utilizing Cloud Run, Compute Engine, Cloud Build, Cloud Storage, and CI/CD pipelines to automate data ingestion, processing, and deployment workflows.Maintained high data accuracy and system reliability by applying detail-oriented validation, testing, and code review practices across backend services and data pipelines.

Designed, audited, and deployed Rust smart contracts for staking, NFT minting, and DeFi protocols, optimizing for gas efficiency, security, and performance in production blockchain environments. Profiled and optimized Rust and TypeScript code paths, improving application performance and end-to-end throughput by 30% and reducing page load latency to under 200 ms. Implemented application monitoring and observability by integrating Sentry, Prometheus, and Grafana to enable real-time error tracking, metrics collection, and alerting, improving system reliability and incident response.

Developed and optimized modern frontend applications using React, configuring Webpack and Vite to improve build performance and development workflow efficiency, reducing build times by approximately 35%. Built comprehensive unit and component tests using React Testing Library, increasing test coverage and improving reliability of UI components before production deployment. Automated build, test, and deployment pipelines using GitLab CI/CD, streamlining frontend deployment workflows and improving release reliability across staging and production environments.

Engineered high-performance backend services in Rust using the Rocket (web framework) framework to power a peer-to-peer marketplace built on Solana, supporting blockchain-based payments and marketplace transactions with sub-200ms API latency.Implemented secure backend transaction workflows for blockchain payments and order processing, enabling thousands of marketplace transactions while maintaining reliable on-chain confirmation handling. Improved backend performance and system stability by introducing structured logging, error handling, and caching strategies, reducing service error rates by ~30% and improving platform reliability.
