Evolvo • Freelance

Mar 2022 - Present • 4 yrs 2 mos

Owned end-to-end architecture and delivery of high-scale, enterprise-grade full-stack applications, driving performance gains, major cost efficiencies, and accelerated innovation in complex cloud native environments using modern JavaScript ecosystems. Architected & productionized scalable microservices platforms with Node.js, PostgreSQL, and AWS serverless/container services (Lambda, ECS/Fargate, RDS, SQS), delivering 60%+ system performance uplift while reducing monthly cloud spend by 30–45% across multiple workloads through optimization and right-sizing. Led frontend platform evolution with React, Next.js (App Router + Server Components), TypeScript, and Tailwind CSS, shipping responsive, high-conversion interfaces that boosted user engagement metrics by ~45% and significantly improved NPS/product satisfaction scores. Designed and rolled out mature, fully automated CI/CD pipelines (GitHub Actions, Docker, multi-env promotions, IaC), slashing manual deployment overhead by >70%, cutting release cycles from weeks to days, and enabling safe, frequent production changes with strong observability foundations. Served as technical lead for cross-functional squads (Product + Design + QA + DevOps), aligning engineering roadmap with business priorities consistently delivered mission-critical features ahead of schedule while managing technical debt and architectural evolution. Mentored and up-leveled multiple junior/mid-level engineers through code reviews, architecture workshops, pair programming, and establishment of clean code principles, comprehensive automated testing culture (unit → integration → E2E), and maintainable documentation measurably improving team velocity, code quality, and long-term maintainability. Acted as strategic technical partner in digital transformation efforts, modernizing legacy footprints into cloud-native, resilient systems that laid the groundwork for future product scaling, rapid iteration, and competitive advantage.
