Designed and built the core architecture of MWXAlpha, a production Web3 intelligence platform spanning backend services, AI processing, market and on-chain data, crypto payments, and smart contracts. Architected stateless backend services using PostgreSQL, Valkey, and BullMQ to support horizontal scaling, distributed workloads, and resilient asynchronous processing. Built social-intelligence workflows monitoring Twitter/X and news sources for crypto signals using LLM-based processing, and developed KOL and wallet monitoring systems using Birdeye, DexScreener, QuickNode, and blockchain RPC services. Designed secure crypto-to-crypto payment flows using Bridge.xyz with server-side verification, transaction correlation, replay protection, and idempotent entitlement handling. Designed and deployed an upgradeable Solidity staking and lock-up smart contract on Base using Foundry, implementing staged unlock workflows, access controls, pause mechanisms, reentrancy protection, and safe token transfers. Designed cross-provider validation and fallback mechanisms for critical external services, including market-data consistency checks and AI-provider failover. Diagnosed and resolved a production partial outage in the AI narrative pipeline by identifying clustering-service overload, applying safe batch limits, and redesigning the workflow around asynchronous jobs, controlled retries, and failure fallbacks. Established operational safeguards using Sentry, PostHog, structured logging, health monitoring, and feed-freshness and error tracking.

Developed and deployed a cloud-based HRIS platform using microservices architecture, reducing deployment time by 30% through CI/CD optimization. Designed and implemented automated functional, regression, performance, and security testing using Selenium, Cypress, and JUnit to improve release reliability and test coverage. Integrated automated quality validation into CI/CD pipelines and established repeatable release-validation processes. Led cross-functional technical delivery activities including sprint planning, release readiness, incident response, and coordination across engineering and QA teams. Mentored junior engineers and QA specialists and established engineering, testing, and release practices across project teams. Implemented performance monitoring and incident-response processes to identify system bottlenecks and improve production stability.

Architected and developed scalable backend services using Java and Spring Boot for HR administration and reporting systems. Designed and maintained RESTful APIs integrating internal systems and third-party services. Optimized SQL queries and database workloads, improving database performance by 40% for data-intensive applications. Collaborated with cross-functional teams to translate business requirements into production backend solutions and conducted internal training on Python and data analysis to support engineering-team development.

Established manual and automated testing practices for enterprise software projects. Built and maintained automated test documentation and suites across functional and regression workflows. Integrated testing into CI/CD pipelines to improve release quality and reduce delivery-cycle friction. Worked with product and engineering teams to translate requirements into test scenarios and quality standards, and used QA metrics and production feedback to identify opportunities for process improvement.
