David Arnal García

- Architected and implemented a microservices platform on AWS (ECS, Lambda, API Gateway) handling 20K+ daily API requests with 200 ms average end-to-end latency and 99.9% uptime via auto-scaling and blue/green deployments. - Built a reusable TypeScript SDK and client libraries (used by Next.js apps) to standardize request/response schemas and integration patterns, accelerating partner onboarding by 30%. - Introduced Redis caching and an optimized rate limiter to cut redundant downstream service calls, delivering a 25% cost reduction and 35% throughput improvement across critical endpoints. - Developed computer science questions and code examples that challenge AI models in languages like Java, Python, JavaScript/TypeScript, C++, Swift, and other programming languages. - Assessed and ranked AI-generated code, identifying bugs, optimization opportunities, and best practices to refine model outputs.

- Built Python scripts to scrape and aggregate on-chain data, enabling quantitative evaluation of 120+ Web3 protocols. - Developed complex SQL queries (Dune/Nansen) to analyze protocol health, tokenomics, and user retention metrics, driving data-backed investment decisions. - Reviewed Solidity contracts to assess technical risks and security vulnerabilities in DeFi protocols.-

- Analyzed user interaction data to optimize the questing mechanics of XOOB (Web3 gaming), directly influencing the platform's gamification logic and retention strategies. - Executed complex SQL queries on Chromia’s relational blockchain structure to monitor network activity and validate game economy performance.
