David Arnal

• Architected and deployed an autonomous agent using LLMs to analyze complex datasets and generate structured execution plans. • Developed a real-time data ingestion system, scraping and normalizing metrics from disparate third-party APIs. Optimized for low-latency updates to drive business-critical dashboards. • Designed and shipped automated alerting bots (Slack integration) that monitor system health and external thresholds in real-time, ensuring 99.9% observability on critical assets. • Translated compl

• Architected a serverless platform on AWS (ECS/Lambda) handling 20K+ daily requests. Achieved 99.9% uptime and <200ms latency through aggressive auto-scaling and blue/green deployment strategies. • Developed a type-safe TypeScript SDK and Next.js client libraries, reducing integration friction and accelerating partner onboarding by 30%. • Engineered a custom rate-limiting solution backed by Redis, reducing redundant downstream calls by 35% and cutting cloud infrastructure costs by 25%.

- 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.
