Why companies trust us with critical systems
We don’t sell developer hours. We sell a predictable outcome, so the rules are the same on every project.
−const d = get(u);−if (d.s === 2) r(d);+const invoice = getInvoice(user);+if (invoice.status === "failed")+ retryPayment(invoice);Code review within one business day
A senior engineer reviews every pull request. The CEO signs off the architecture.
A demo every two weeks
You see working software, not status reports.
Estimates as ranges, no surprises
Estimates are updated weekly. We flag risks before they happen.
Your code and access from day one
The repository, infrastructure and documentation belong to you.
Seniors on critical paths
Juniors don’t touch payments, security or the system core.
Secure by default
Threat modeling, static and dynamic analysis, and a pentest before release, not after an incident.
How a project runs
You see the first working result two weeks after development starts.
- 01
Discovery
2-4 weeksWe map your processes, systems and constraints. You get an architecture, a plan, a ranged estimate and a risk map.
- 02
Architecture
alongside the planWe design for load, security and integrations, and put every decision in writing.
- 03
Delivery
two-week sprintsA demo every two weeks and a weekly report on schedule and budget.
- 04
Launch
no business downtimeLoad tests, a pentest and a rollback plan. We cut over without stopping operations.
- 05
Support
SLA up to 99.95%24/7 on-call and ongoing development by the same team.
An engineer runs the company
“Large companies don’t need heroics on a Friday night. They need systems that don’t go down and deadlines they can believe.”
An engineer runs the company
Ben started as a developer in card processing, built engineering teams at large product companies and founded Parker to deliver enterprise software without bureaucracy or death marches. He speaks at major tech conferences about engineering culture.

Three ways to work with us
We choose together after the first meeting. You can start with one and switch to another.
| Parameter | Fixed-scope project | Dedicated team | Audit and project rescue |
|---|---|---|---|
| Best when | The goal is clear and you need it delivered on time | You need to scale your own engineering fast | A project is stuck or inherited from another vendor |
| How you pay | A fixed price per phase after discovery | Monthly, for the team you agree on | A fixed price for the audit |
| Start | Two weeks after signing | A team in 10 business days | Report and plan in 3 weeks |
We take on projects from $150k and work with companies for whom software is critical.
Frequently asked questions
A typical project runs from $150k to $2M. You can start with a 2-4 week discovery at a fixed price.
Yes. We’ll send our template or sign yours.
A dedicated team: a tech lead, an architect, senior engineers, QA and a project manager. We agree on the lineup before kickoff.
You’ll know before it happens: estimates are updated every week and risks are raised right away.
Yes. We work on-premise, in closed networks and in your cloud accounts, with your tools and approval process.
Yes, that’s a separate engagement. We start with an audit of the code and infrastructure.
Tell us about your project
Within three business days we come back with a plan, a team lineup and a ranged estimate. The first consultation is free.
