About this gig
Turn a complex business workflow into a polished, working SaaS feature.
I bring 20+ years of software development experience and combine UI/UX design with full-stack delivery. I led design and development for Tanvelo, CaterScale, Coverstride, and Vet Aftercare, and currently design and build interfaces at AIRIA.
Work can include:
- User flows and interface design in Figma
- Responsive Angular/TypeScript screens
- Node.js/NestJS or C#/.NET APIs
- PostgreSQL/database work and role-based access
- Integrations, testing, source code, and handoff notes
I use Claude and Codex to support implementation and debugging, with hands-on architecture, review, and testing.
Packages cover one agreed feature or workflow with up to 2, 4, or 6 screens. Standard includes one integration; Premium includes two. Complete platforms, complex migrations, payment infrastructure, and major new architecture need a custom quote.
Send your brief or existing product before ordering so we can confirm scope, access, and acceptance criteria.

I design and build SaaS products, from Figma prototypes to working applications. With 20+ years in software development, I connect clear UX with APIs, databases, integrations, and deployment. I led design and development for Tanvelo, CaterScale, Coverstride, and Vet Aftercare, and design and build AIRIA's interfaces. My stack: Angular, TypeScript, Node.js/NestJS, PostgreSQL, and C#/.NET. I use Claude and Codex for faster iteration, with hands-on code review and testing. Earlier credits include financial-services software, Disney game development, and Square Enix consulting.

FAQ
What technologies do you use?
My core stack is Angular/TypeScript, Node.js/NestJS, PostgreSQL, and C#/.NET. I design features in Figma before implementation and can work with existing systems. We agree on the stack and integrations before starting.
Does a package cover an entire SaaS product?
Each package covers one agreed feature or workflow, with the listed screen and integration limits. A complete SaaS platform, complex migration, or major new architecture needs a custom quote. Please message me before ordering to confirm the scope.
Can you improve an existing application?
Yes. I can redesign and implement a focused feature in an existing SaaS product. Share the current workflow, stack, designs, and integration details so we can agree on requirements and acceptance criteria.
How do you use Claude and Codex?
I use Claude and Codex to support implementation, debugging, and iteration. I remain responsible for architecture, design decisions, code review, testing, and delivery. We can agree on any project-specific AI requirements before starting.
