Engineering for software that has to hold up in production

AMPQ is a principal-led engineering practice. We build products end to end, advise on architecture, security and modernization, and run the cloud platforms underneath, with deep experience in fintech and regulated industries.

What we do

Each service can be booked on its own, and they are designed to combine: an assessment that leads into the fixes, or a product built on a platform set up for it.

Build Test Deploy Interface API Data

Product development

Web applications and APIs built end to end: .NET and Rails backends, React and Next.js frontends, typed contracts between them, background job pipelines, and test suites that let a team keep shipping after we leave.

  • New products and MVPs
  • APIs and backend services
  • React and Next.js frontends
  • Test automation and CI
Findings

Technical consulting

Architecture reviews, security audits and modernization plans for systems that have outgrown their first design, with remediation carried through to merged code. A fractional CTO when you need senior technical leadership without a full-time hire.

  • Architecture and code review
  • Security audit and remediation
  • Legacy modernization
  • Fractional CTO
Primary region Standby region Registry Replication

Platform engineering

Azure estates run through Terraform, Container Apps and AKS. Monitoring that pages the right person, disaster recovery with written runbooks, and delivery pipelines that can be rebuilt from nothing.

  • Cloud platform and cost assessment
  • Terraform and CI/CD
  • Observability and alerting
  • Disaster recovery program

Products and open source

Built, sold and supported in house, on the same stack and practices we bring to client work.

How engagements work

Most clients start with an assessment. Each option also stands on its own.

Assessment

2 to 3 weeks, fixed price

We read the code, the infrastructure and the incident history, then deliver a written report of findings ranked by risk and cost, with a remediation plan your team can execute.

Delivery

Scoped project with milestones

We build what the assessment or your team scoped, in your repositories and under your review process, until it runs in production.

Fractional CTO

Monthly retainer

Part-time technical leadership: architecture and platform decisions, hiring, incident reviews and delivery process, working next to your founders and engineers.

Who you work with

Ten years of software engineering, most of it in fintech: treasury and FX systems at FIS, then payments and platform leadership at a regulated lender, covering payment pipelines, a 40-service Azure estate, incident response and security.

Before that, three years at Bexel Consulting as a software developer and BIM manager on tunnel and stadium projects. Civil engineering degree from the University of Belgrade.

Has led engineering teams of up to six and run company-wide technical hiring. Writes production code on every engagement.
