About

Professional summary

I am a software engineer with experience building full-stack web applications, data-intensive workflows, and interactive user interfaces. I work across frontend and backend systems, from designing user experiences to implementing APIs, authentication, data persistence, and cloud-based file storage.

I currently help architect and deliver a greenfield government application at Booz Allen Hamilton. I have contributed to the MVP in a fast-paced environment while working with Next.js, NestJS, TypeScript, PostgreSQL, Drizzle ORM, Keycloak, and Amazon S3.

My technical background includes React, Node.js, Java, Python, JavaScript, TypeScript, SQL, Spring Boot, Flask, and FastAPI. I enjoy building scalable systems and solving complex product problems involving forms, tables, data validation, filtering, sorting, pagination, and record management.

I have experience with data visualization and geospatial interfaces, including MapLibre and Deck.gl. Previously at Rose AI, I built data-upload and charting capabilities, improved chart-generation performance using OpenAI's Completions API, and supported product improvements for user engagement.

I also bring experience collaborating with teams, interviewing candidates, mentoring new hires, and providing technical leadership. I hold an active United States Department of Defense Secret Security Clearance.

Career history

Software Engineer Booz Allen Hamilton

I played a key role in architecting and building a greenfield government application as one of a small group of engineers responsible for delivering its MVP in a fast-paced environment.

I worked across the user interface, backend APIs, authentication, data persistence, and file storage using Next.js, NestJS, TypeScript, PostgreSQL, Drizzle ORM, Keycloak, and Amazon S3. I engineered data-intensive workflows with complex forms and TanStack Tables, including validation, filtering, sorting, pagination, and record management.

I also built interactive geospatial functionality using MapLibre and Deck.gl to support a feature-rich mapping interface for data visualization.

Software Engineer Rose AI

I delivered a full landing-page redesign in under a week to support fundraising efforts, then continued making updates and improvements after launch.

I built a file-upload system that converted Excel and Google Sheets data into charts using custom charting software, contributing to a 10% increase in consistent user engagement. I also improved chart-generation performance by 20% by leveraging OpenAI's Completions API for smoother chart editing.

I participated in interviewing candidates and mentored engineers who joined the team.

Software Engineer Expression

I delivered scalable full-stack solutions for multiple NDA-protected Department of Defense projects, taking work from design through deployment.

I focused on developing new features and resolving frontend issues using React. I also provided technical leadership for integrating Storybook and Bit.dev into the development workflow.
