Compliance Infrastructure
Built to Hold Up to Scrutiny.
We build compliance infrastructure on Scala and the JVM where regulatory rules are encoded in the type system, audit trails are immutable by design, and every state transition is traceable. For fintech companies where getting compliance wrong is not a recovery situation.

Why Scala for compliance infrastructure
Compliance systems need a language where
rules are enforced, not just documented.
What we build
Scala compliance infrastructure capabilities.
01
Compliance rule engines
AML, KYC, and sanctions screening systems.
We build compliance rule engines that evaluate AML velocity checks, sanctions screening, KYC validation, and PEP exposure checks concurrently in the transaction path. Built on Cats Effect and ZIO with pure function rule definitions that are fully testable in isolation and auditable in production.
02
Immutable audit trail infrastructure
Tamper-proof event logs for regulatory review.
We build immutable audit trail systems that record every compliance-relevant state transition with a timestamp, the rule that triggered it, and the data that was evaluated. Built on Kafka and Delta Lake so the audit log is append-only, reproducible, and survives any downstream system failure.
03
Regulatory reporting pipelines
CTR, SAR, and MiFID II reporting on Spark.
We build the regulatory reporting pipelines that produce Currency Transaction Reports, Suspicious Activity Reports, and MiFID II transaction reports from your financial data. Built on Apache Spark and Scala with the data lineage and reproducibility that regulators require when they ask how a number was computed.
04
Real-time transaction monitoring
Streaming compliance checks at transaction velocity.
We build real-time transaction monitoring systems that evaluate compliance rules at the speed of your transaction flow. Kafka and Akka Streams process events with the throughput and ordering guarantees that compliance monitoring requires, without creating a bottleneck in the payment path.
05
KYC and onboarding infrastructure
Type-safe identity verification and customer onboarding.
We build KYC and customer onboarding backends that manage identity verification workflows, document processing, and ongoing customer due diligence with the type safety and audit trail requirements that regulated onboarding demands. Every decision is recorded, traceable, and defensible.
06
Compliance data governance
Data lineage and governance for regulated financial data.
We build the data governance infrastructure that compliance programs depend on: data lineage tracking, retention policy enforcement, access logging, and the schema governance that prevents compliance-relevant data from drifting silently across systems and environments.
Built for compliance
The four properties every compliance
system must guarantee.
01
Enforceability
Compliance rules are encoded in the type system, not just documented. Violations are caught at compile time before they reach production, not discovered during a regulatory examination.
02
Traceability
Every compliance decision traces back to the rule that triggered it and the data that was evaluated. No black boxes, no untraceable outputs, no decisions that can't be explained to a regulator.
03
Immutability
Audit logs and compliance records are append-only and tamper-proof. Historical states are reproducible. When a regulator asks what your system knew and when, you can answer precisely.
04
Completeness
Every compliance-relevant event is captured. No gaps under load, no missing records during system failures, no partial audit trails that create regulatory exposure during an examination.
Common questions
Questions we get before the first call.
If your question isn't here, it takes one conversation to answer it.
Talk to us →Do your engineers have experience with regulated financial environments specifically?
Yes. We match clients with engineers who have built compliance infrastructure in regulated fintech environments: AML rule engines, regulatory reporting pipelines, KYC systems, and audit trail infrastructure. Experience in regulated environments is a requirement, not a nice-to-have.
Which regulatory frameworks have your engineers worked with?
Our engineers have worked on systems with PCI DSS, PSD2, MiFID II, AML and BSA requirements, GDPR data governance, and SEC reporting obligations. The specific framework matters less than the engineering discipline — the underlying patterns for audit trails, rule engines, and regulatory reporting are consistent across most frameworks.
Can you integrate with our existing compliance tooling and data providers?
Yes. Whether you're using a third-party sanctions data provider, an existing KYC vendor, or internal risk data sources, our engineers build the integration layers that connect them to your Scala compliance infrastructure. We work within your existing vendor relationships rather than replacing them.
Our current compliance system has audit trail gaps. Can you fix that without a full rebuild?
In most cases yes. We assess what's missing, identify the highest-risk gaps, and implement targeted fixes that close the audit trail without requiring a full system replacement. A complete rebuild is sometimes the right answer, but we don't recommend it unless the existing system is beyond incremental repair.
How quickly can engineers be contributing to our compliance codebase?
Most engineers are contributing within days. They come in knowing Scala, the compliance domain, and the operational constraints of regulated systems. We don't do multi-week onboarding periods and we don't send generalists into compliance codebases.
