Compliance Engineering
SOC 2 aligned engineering, compliance-focused code review, and control implementation guidance.
Fintech software engineering where compliance and velocity both matter
Fintech teams move fast in regulated environments where payment data handling, SOC 2 evidence, PCI controls, and security review are part of every release cycle. Maxiom engineers build and oversee fintech software with compliance controls implemented in code — encryption, access management, audit logging, and change management evidence auditors can verify. We also provide AI code oversight for high-risk payment and authentication flows, tech debt resolution for high-growth codebases, and fractional CTO advisory for infrastructure and fundraising decisions.

The problem
PCI and SOC 2 compliance
Payment and customer data handling requires controls implemented in code: encryption, access management, audit logging, and change management evidence that auditors can verify.
AI-generated code in payment or data handling flows
AI tools accelerate feature delivery but can introduce vulnerabilities in authentication, input validation, and secrets management in high-risk code paths.
Tech debt in high-growth fintech codebases
Rapid growth leaves shortcuts in core systems. Debt compounds until it slows enterprise sales cycles, increases incident rates, or fails due diligence.

Frequently asked questions
What fintech software engineering services does Maxiom provide?
SOC 2 aligned compliance engineering, AI code oversight for payment and authentication flows, technical debt resolution for high-growth codebases, and fractional CTO advisory for infrastructure and fundraising due diligence.
Can Maxiom review AI-generated code in payment flows?
Yes. Senior engineers independently review AI-assisted code in authentication, input validation, secrets management, and payment data handling paths — where AI tools most commonly introduce vulnerabilities.
Does Maxiom have SOC 2 and PCI compliance experience?
Yes. Engineering under SOC 2 and compliance frameworks where audit evidence comes from code implementation — encryption, access controls, audit logging — not security questionnaires alone.
How does Maxiom help high-growth fintech teams with tech debt?
Structured debt inventory and prioritized remediation restore velocity without stopping product delivery — important when growth shortcuts start slowing enterprise sales or raising incident rates.
Can fractional CTO advisory support a fintech fundraise?
Yes. Advisory covers technical narrative for fundraising, due diligence readiness, infrastructure decisions, and board-level risk reporting with accountable senior ownership.
What security areas get the most attention in fintech reviews?
Authentication, secrets handling, input validation, payment data paths, audit logging, and change-management evidence — the controls auditors and enterprise customers scrutinize first.
Do you build new fintech systems or review existing ones?
Both. Maxiom delivers compliance-aligned engineering for new systems and independent oversight or remediation for existing codebases approaching SOC 2, customer security review, or due diligence.
Will Maxiom process our fintech codebase through third-party AI tools?
No. Client code stays in client environments. Reviews and delivery use senior engineer inspection and established methods — proprietary source is not run through third-party AI tools.
How do fintech engagements start?
With a scoping conversation about stack, compliance context (SOC 2, PCI-related controls), and timeline. Written scope and NDA come before any repository access.
