Senior engineering. Software that
works.

We build products and the systems that keep them running.

What We Do

We design and ship software for new products, complex workflows, and operationally critical systems.

Product Engineering

We build applications, APIs, and internal tools to stay useful and maintainable long after launch.

Data Platforms

We design ledgers, reporting stores, migrations, and query paths around correctness and auditability.

Reliability & SRE

We cover availability targets, backups, incident response, and runbooks for systems that cannot rely on luck.

Security & Compliance

We map threat modeling, encryption, access control, and audit preparation to PCI, GDPR, and internal risk requirements.

System Integration

We connect third-party APIs, banking rails, CRMs, ERPs, and legacy services with explicit contracts and failure handling.

Cloud Architecture

We handle infrastructure-as-code, network design, CI/CD, and cost control across AWS, GCP, Azure, and bare Linux.

Expertise

Practical engineering depth where products get difficult

Fintech

Financial Products & Payment Rails

We build payment orchestration, settlement engines, reconciliation, and risk scoring for acquirers, PSPs, and financial products. The work is shaped by PCI-DSS, audit trails, chargebacks, and the ways payments fail in production.

  • Card Acquiring
  • ISO 8583
  • 3-D Secure
  • Cross-Border FX
  • Pix
  • Swish
  • SEPA Instant
  • PCI-DSS
Bitcoin

Bitcoin & Lightning Network

We build Bitcoin payment infrastructure, wallet flows, multisig cold storage, LND and Core Lightning channel operations, and Ark payment rails for teams making deliberate custody and settlement choices.

  • LND
  • Core Lightning
  • BOLT12
  • Ark
  • Taproot
  • Miniscript
  • Multisig
  • PSBT

Applied ML & Inference

We build risk scoring, classification, and inference services with measurable latency, reviewable outputs, and production monitoring.

Real-Time Systems

We build event streams, WebSocket APIs, queues, and workers for market data, payment state, notifications, and operational dashboards.

Threat Detection & Mitigation

We tune fraud signals, anomaly detection, abuse controls, and response workflows to detect threats early and reduce financial losses.

Observability & SRE

Metrics, traces, logs, alerts, SLOs, and on-call routines make production behavior visible before customers report it.

How We Work

From prototype to production.

You work directly with the engineers who design and build your systems.

Selected client work

Clients include both regulated and unregulated entities. For several, we designed and built their systems and continue to support them in production at scale.

Engagement

Three ways to work together

The same senior engineers in all three. Only the commitment changes.

Advisory

Hourly

Senior engineers review the work and recommend a direction. Most valuable before audits, migrations, and major decisions.

Architecture and code review, performance and latency work, security assessment, technology and vendor selection, team mentoring, and due diligence for M&A.

For independent advice and review rather than delivery ownership.

Project

8 to 24 weeks

We fix the scope, own the delivery, and bill by milestone.

Full-stack applications, proofs of concept and product launches, payment and fintech systems, ML-backed risk and operations tools, API and integration platforms, and cloud and Linux infrastructure.

For a defined scope with clear deliverables and an agreed endpoint.

Partnership

6+ months

We provide ongoing engineering capacity to develop, maintain, and support your systems as they grow.

An embedded engineering team with planned capacity, direct Slack or Teams access, roadmap collaboration, incident support and SLAs, and quarterly technical reviews.

For ongoing development and support rather than a one-off build.
