Product builds, infrastructure, and the systems behind them.
Applications, APIs, and internal tools that stay useful and maintainable long after launch.
Ledgers, reporting stores, migrations, and query paths designed around correctness and auditability.
Availability targets, backups, incident response, and runbooks for systems that cannot rely on luck.
Threat modeling, encryption, access control, and audit preparation mapped to PCI, GDPR, and internal risk requirements.
Third-party APIs, banking rails, CRMs, ERPs, and legacy services connected with explicit contracts and failure handling.
Infrastructure-as-code, network design, CI/CD, and cost control for AWS, GCP, Azure, and bare Linux.
Payment orchestration, settlement engines, reconciliation, and risk scoring for acquirers, PSPs, and financial products. We build around PCI-DSS, audit trails, chargebacks, and operational failure modes.
Bitcoin payment infrastructure, wallet flows, cold storage design, BTCPay Server, LNURL, and Lightning channel operations for teams making deliberate custody and settlement choices.
Risk scoring, classification, and inference services with measurable latency, reviewable outputs, and production monitoring.
Event streams, WebSocket APIs, queues, and workers for market data, payment state, notifications, and operational dashboards.
Fraud signals, anomaly detection, abuse controls, and response workflows tuned for the point where bad traffic becomes money loss.
Metrics, traces, logs, alerts, SLOs, and on-call routines that make production behavior visible before customers report it.
Direct access to senior engineers and the team building it. Decisions made close to the code, not in committee. No proxy conversations, no slide decks.
Three flexible models designed to match your project scope, timeline, and budget.
