Throughout my career, I have developed deep hands-on expertise across backend systems, data engineering, and modern JavaScript architectures. I take pride in my track record of technical ownership, cross-functional leadership, and delivering complex initiatives from concept to production. My experience spans leading large-scale refactors of mission-critical platforms, driving architectural redesigns, and decomposing legacy monolithic services into modular, service-oriented components. I am passionate about improving developer velocity and code quality by introducing and standardizing technologies such as TypeScript across backend services. I have collaborated closely with stakeholders across engineering, product, and business teams to align technical direction with evolving requirements. Leveraging AI-assisted development tools, I accelerate refactoring, test scaffolding, and technical documentation while maintaining high standards. I have led modernization efforts for high-traffic client-facing platforms, designed real-time ETL pipelines, and implemented event-driven architectures to support analytics and reporting. My leadership roles have involved mentoring engineers, establishing development standards, and improving CI/CD processes to increase delivery quality and team velocity. I am experienced in building high-performance APIs, managing authentication and authorization services, and balancing hands-on development with technical leadership. I am committed to driving operational efficiency, observability, and support workflows through internal tooling and platform initiatives. Throughout my career, I have contributed to open-source projects, improved application performance, and established engineering standards and migration strategies. I am eager to continue leveraging my skills to lead and deliver impactful software engineering solutions. ## Skills ### [Python](https://jobicy.com/talent/python.md)[SQL](https://jobicy.com/talent/sql.md)[AWS](https://jobicy.com/talent/aws.md)[JavaScript](https://jobicy.com/talent/javascript.md)[React](https://jobicy.com/talent/react.md)[Docker](https://jobicy.com/talent/docker.md)[CI CD](https://jobicy.com/talent/ci-cd.md)[TypeScript](https://jobicy.com/talent/typescript.md)[Git](https://jobicy.com/talent/git.md)[MySQL](https://jobicy.com/talent/mysql.md)[Mentoring](https://jobicy.com/talent/mentoring.md)[Microservices](https://jobicy.com/talent/microservices.md)[MongoDB](https://jobicy.com/talent/mongodb.md)[React Native](https://jobicy.com/talent/react-native.md)[Next.js](https://jobicy.com/talent/next-js.md)[Redux](https://jobicy.com/talent/redux.md)[Flask](https://jobicy.com/talent/flask.md)[Express](https://jobicy.com/talent/express.md)[MariaDB](https://jobicy.com/talent/mariadb.md) ## Experience Lead Senior Engineer @ ADP / Sora Apr 2025 - Present Leading large-scale refactors of a mission-critical employment onboarding platform, improving modularity, fault isolation, and long-term maintainability.
