My work focused on practical frontend development, engineering foundations, and individual learner support.

I led frontend development and improved application load times by approximately 60% through performance optimization, architecture improvements, and improved data-access patterns. I designed the RQM frontend architecture, separating raw data, queries, and models to streamline end-to-end testing and speed up implementation for interfaces using unstable APIs.

I designed JavaScript backend architecture using NestJS, Fastify, Adonis.js, Python, Redis, and microservices in a multi-tenant, event-driven environment. I implemented deterministic error handling, unit tests, GitHub Actions CI/CD workflows, responsive interfaces from Figma designs, and REST and WebSocket integrations.

I mentored junior engineers in coding standards, debugging, and structured problem-solving. Technologies included AWS Amplify, Microsoft Entra ID, React.js, Svelte, NestJS, Adonis.js, PostgreSQL, Redis, MongoDB, Umi.js, Ant Design, and FastElement.

I provided ongoing technical support for applications created during my prior full-time engagement with the company. I helped maintain existing systems and supported continuity for technical operations.

I also conducted candidate interviews to support the hiring of the next engineering team.

I built an ERP system for a property management company, supporting processes from property acquisition through booking. I developed PHP and Laravel REST APIs for web and mobile applications and built Vue.js web platforms.

I designed and optimized relational database schemas, relationships, and indexes, migrated legacy systems while preserving compatibility, and deployed closed-source customer applications to private data centers over an AT&T private network.
