About

I am a Founding Engineer and Staff Software Developer who thrives on building innovative products from the ground up. For the past six months, I've been focused on creating "Pump It Better," an offline-first fitness application for web, Android, and iOS. In this role, I've been responsible for everything from the core architecture and technology selection (React, TypeScript, NestJS, RxDB, PostgreSQL) to building out the CI/CD pipeline and deploying the infrastructure on Fly.io. My passion lies in solving complex problems for early-stage companies. I specialize in: - Greenfield Product Development: Taking ideas from a blank canvas to a fully functional, production-ready application. - Modern Frontend & Backend: Leveraging React, TypeScript, and Node.js to build robust and maintainable systems. - Full-Stack Architecture: Designing and implementing everything from the database schema and API (REST/GraphQL) to the user interface. - DevOps & Automation: Creating efficient development-to-production workflows with tools like Nx, GitHub Actions, and Docker. After successfully launching my application, I am seeking my next challenge. I am looking for a remote opportunity - whether fractional, contract, or full-time - where I can help a startup build its foundational technology, establish a strong engineering culture, and deliver an exceptional product.

Founding Engineer

Oct 2025 – Present · 7 mos

● Offline-First System Architecture: Architected a resilient local-first data strategy using RxDB and PostgreSQL, enabling full app functionality without internet connectivity. Designed a custom bidirectional synchronization engine with Last-Write-Wins conflict resolution, ensuring data consistency across multiple user devices.
● Cross-Platform Application Delivery: Engineered a high-performance monorepo utilizing Tauri v2 and React Router 7 to deploy a single codebase to Web, Android, and iOS. Achieved 95% code sharing while delivering native performance traits and deep system integration.
● Full-Stack & DevOps Strategy: Built a type-safe backend ecosystem using NestJS, Prisma, and TypeScript. Established automated CI/CD pipelines via GitHub Actions and Fly.io for zero-downtime deployments, creating a robust infrastructure for rapid feature iteration.
● Product Lifecycle Ownership: Directed the complete zero-to-one product journey, transforming ambiguous requirements into a production-grade application. Managed the full SDLC including schema design, UI/UX implementation, and public beta launch strategies.

Staff Software Engineer

Oct 2019 – Sep 2025 · 5 yrs 11 mos · Remote · Remote

● Bootstrapped and scaled the MasterMind TMS frontend (React, TypeScript, Apollo
GraphQL) from early formation into a multi-module platform owning Records, Patterns,
and Flatfile automation interfaces end to end.
● Designed reusable form, validation, and layout patterns (Formik + Zod) that
streamlined development and kept UX behaviors consistent across new entities.
● Implemented disciplined GraphQL usage (fragments, generated types, mutation
conventions) to reduce duplication and improve safety during ongoing service
iterations.
● Collaborated with backend engineers as services transitioned to .NET microservices
shaping API contract details (field granularity, pagination, error handling) for
frontend efficiency.
● Performed targeted UI performance improvements (query refinements, render
optimization, component boundary tuning) to maintain responsiveness under growing data
complexity.
● Built and maintained Cypress end-to-end flows and Jest unit test suites for critical
operations.
