Senior engineering for teams that are stretched thin.

We work with small and mid-sized companies whose developers are busy, outnumbered or gone. We take the hard tickets, connect the systems, modernize what's old and leave clear notes behind.

API and third-party integrations

When your CRM, payment processor, store, ERP and accounting tools don't share data, people fill the gap by hand. We connect them so data moves on its own and every run leaves a record.

  • Two-way syncs between business systems through their APIs or webhooks.
  • Scheduled jobs that import, clean and export data, with alerts when something fails.
  • Payment and checkout flows, including subscriptions, which we built for our own product, Gritfolio.
  • Your own API, documented, so partners and future developers can build on it.

How we build integrations

Legacy .NET and PHP modernization

Older applications usually still work. The problem is that every change is slow and every deploy is a risk. We modernize in stages, so the business keeps running while the code gets easier to change.

  • An honest assessment first: what to keep, what to replace and what it will cost.
  • Framework and runtime upgrades, including moving older .NET Framework code forward.
  • Dashboard and admin rebuilds that the team uses every day.
  • Tests and deploy automation added around the parts that change most.
For Step and Rail we modernized the CakePHP business dashboard their team runs on every day. See our work.

How we modernize legacy apps

Hard production bugs

A hard bug has often been "fixed" more than once before anyone finds the cause. We reproduce the problem, find the actual cause, fix it, and write up what happened so your team isn't surprised by it again.

  • Intermittent failures in background jobs, integrations and deploys.
  • Slow pages and queries, traced to the code or the database.
  • Data that doesn't add up between systems or reports.

Production bugs and project rescue

Taking over a project from another developer

When a developer leaves or an agency moves on, you are left with code nobody on your side understands. We take it over without a rewrite unless one is truly needed.

  • Access and inventory: repositories, hosting, domains, keys and accounts moved into your control.
  • A plain-English report on the state of the code and the risks in it.
  • A short list of fixes in priority order, then we keep the work moving.

How a takeover works

Database and data problems

Slow reports, duplicate records, migrations that have to go right the first time. We work directly in SQL databases and the code around them, and we test migrations against a copy before touching production.

Fractional CTO help

Some companies don't need another developer as much as they need someone senior to make technical calls. We help with architecture, build-versus-buy decisions, vendor and hiring reviews, code reviews and a roadmap your team can follow.

It is billed at our normal hourly rate, usually as a monthly block of hours you choose, so you can scale it up or down.

AI automation

We build automation that runs in production, with logs, limits and a person approving the steps that matter. It has its own page, and the best way to start is the fixed-price AI Opportunity Audit.

How an engagement works

  1. Call

    A 30-minute call with an engineer about the problem, your stack and your deadline.

  2. Written estimate

    Hourly with a range, or a fixed price when the scope is clear. No work starts without your sign-off.

  3. Work in your tools

    We work in your repository and issue tracker and follow your review process.

  4. Handover

    Notes on what changed and why, so your team can carry it forward.

Questions about working with us

What do you charge for software development?
Senior engineering is $100 to $125 per hour. When the scope is clear enough, we quote a fixed price instead. See the pricing page.
Which technologies do you work with?
C# and .NET (including ASP.NET Core, MVC and .NET Framework), SQL Server and other SQL databases, REST and SOAP APIs, Azure, React and TypeScript, Node.js, React Native, PHP including CakePHP, and modern hosting such as Cloudflare and Vercel. If your stack is something else, tell us what it is and we will say honestly whether we are a good fit.
Can you work alongside our existing developers?
Yes. Companies with a small or overloaded team are who we built Codegrity for. We work in your repository, follow your review and release process, and document what we change.
Do you sign NDAs?
Yes. We are happy to sign an NDA before you share details or code.
Who owns the code?
You do. Code we write for you, and your domains and accounts, belong to your company.
