Senior .NET engineer.I build web apps, SaaS MVPs and internal tools for small businesses, start to finish.

You work with me directly, from the first call to launch day. I'll give you a fixed price before I start, show you working software every week, and hand everything over when we're done.

I can take on one new project from November 2026.

Fixed price
You get one price in writing before I start, and it doesn't creep.
A demo every week
Every week you see what's working, not a status report.
You own the code
It lives in your GitHub and your cloud account from the first day.
A proper handover
Docs, tests and a recorded walkthrough, so anyone can pick it up after me.

What I can build for you.

Every project starts with a short call. After that you get a written proposal with a fixed price.

01

Web app or SaaS MVP

THIS IS FOR YOU IF
You have an idea, or a way of working, that off-the-shelf software doesn't handle well.
WHAT YOU GET
Sign-in and user roles, your core workflow, payments if you charge for it, an admin area, and hosting on your own account. Enough to put in front of real customers.
HOW LONG
Usually 6 to 12 weeks
02

Internal tool or automation

THIS IS FOR YOU IF
Your team runs things on spreadsheets, email and a lot of copying and pasting.
WHAT YOU GET
One place for your data, the forms and approvals your team actually uses, the reports you keep rebuilding by hand, and connections to the tools you already pay for.
HOW LONG
Usually 2 to 6 weeks
03

Fixing an existing .NET app

THIS IS FOR YOU IF
You have a .NET app that's slow, keeps breaking or is stuck on an old version, and the person who built it has moved on.
WHAT YOU GET
I start with a review and a written plan. Then I upgrade it to current .NET, fix what's breaking, add tests and a proper deploy, and write it all down.
HOW LONG
Usually 4 to 10 weeks

AccrenzaAccrenza Health dataMany agencies, one systemWeb, desktop and phone

Software that runs a home care agency, built start to finish by me.

I started Accrenza after hearing the same complaints from home care agencies over and over. I built it the way I build for clients: a written plan, every screen designed before it was coded, and small releases that actually work. It's the best example of what I can do. The screens below use made-up data.

The problem

Home care agencies here run their visits, payroll and billing out of spreadsheets, a state portal and a lot of phone calls. Starting July 2026, Minnesota wants 80% of visits verified electronically. Most agencies only find out they're behind when the quarterly review shows up.

What made it hard

  • It handles health data, so each role sees only what it needs and every access is logged.
  • Each agency's data is walled off in the database itself, not just in the app code.
  • The state changes its rules every year, so the rules live in settings an admin can edit.
  • It's just me, so I cut fifteen features before writing any code.

What I built

An office app where the schedule, the verified visit, the claim and the payroll come from the same record, so the numbers always agree. Accrenza Connect handles calls, texts and a shared inbox. Accrenza Mobile is what caregivers use during a visit. There are AI agents too, but they only make suggestions. A person always signs off.

How I work

How a project runs.

  1. 01

    A short call

    Twenty minutes to hear about your business and what's getting in the way. You don't need to prepare anything. If I'm not the right fit, I'll tell you and suggest someone who is.

  2. 02

    A fixed-price proposal

    A few days later you get a written proposal: what's included, what isn't, the milestones and one price. You'll know the cost before any work starts.

  3. 03

    Weekly demos

    Every week I show you working software and send a short note on what's next. If something needs to change, we catch it early, while it's still cheap.

  4. 04

    Handover

    The code is already in your account. At the end you also get documentation, tests and a recorded walkthrough. Any support after launch is written into the proposal.

What you get

You own all of it. Nothing depends on me.

  • The source code, in your repository from day one
  • Hosting on your own cloud account, in your name
  • Documentation another developer can follow
  • Automated tests for the parts that matter most
  • A recorded walkthrough of the finished system
  • A signed scope and a fixed price before we start
Working with me

A few things worth knowing.

What I build with

Mainstream tools with long support lives, so you can still hire people for them years from now.

Design before code

I design every screen first, and you sign off before I write any code. You see the product before it's built, and the design files are yours to keep.

Testing and documentation happen every week as I go, so there's no scramble at the end.

A few lines is plenty. I'll write back within a business day, and if it makes sense we'll set up a call.

A rough idea is fine.
