Trey E
About this gig
I'm a senior full-stack engineer with 35+ years of combined enterprise software experience, having delivered production applications for CVS Health, JPMorgan Chase, BellSouth, and ESPN.
I build complete, production-ready web applications from database design and backend APIs through polished frontend interfaces. My core stack is Java Spring Boot, Angular, React, MySQL/PostgreSQL, and REST APIs, with real-world experience integrating payment gateways (Stripe, Authorize.Net), OAuth2 authentication, and third-party services.
Whether you need a new app built from scratch, an existing app modernized, or a broken project rescued and finished, I deliver clean, secure, maintainable code not a templated site.
What I can build for you:
- Full-stack apps (Angular/React + Spring Boot)
- REST APIs and backend services
- Database design (MySQL, PostgreSQL)
- Payment gateway and third-party integrations
- Authentication and app security (OAuth2)
- Legacy modernization and bug fixes
Message me before ordering with your requirements, and I'll help scope the right package.

FAQ
Do you provide the source code and full ownership?
Yes. You receive complete source code and full ownership rights upon final delivery and payment. No licensing restrictions.
Can you work with my existing codebase instead of building from scratch?
Absolutely. I regularly take over, fix, and modernize existing Angular, React, and Spring Boot applications. Share your repo and requirements before ordering so I can scope it accurately.
Do you handle both frontend and backend, or just one?
Both. I build the full stack — Angular or React frontend, Spring Boot backend, and database layer — as one cohesive application, not disconnected pieces.
What if my project doesn't fit neatly into one of your packages?
Message me with your requirements before ordering. Most real projects are custom-scoped — I'll recommend the right package or put together a custom offer.
Do you help with deployment, or just delivery of code?
Deployment assistance is included in the Premium package, and available as an add-on for Basic/Standard. I have hands-on production deployment experience (Docker, VPS hosting, CI/CD).
What do you need from me to get started?
A clear description of what you're building or fixing, any existing code/designs, and your target timeline. The more detail upfront, the more accurate the scope and delivery time.
