01 — THE PROBLEM WE'RE HIRED FOR

Growth is what exposes a backend. The monolith that served the first ten thousand users starts timing out at a hundred thousand; deploys become events people schedule around; and when something breaks, nobody can see where. By the time the symptoms are visible to customers, the architecture debt is already expensive.

We engineer platforms as event-driven, observable systems from the start: services that degrade gracefully instead of falling over, APIs with contracts your integrators can trust, and telemetry that answers "what happened?" in minutes rather than war-room hours.

02 — WHAT'S INCLUDED

Event-driven services

Kafka-style event backbones that decouple critical paths from downstream work — a slow partner integration or batch job can never block the request your customer is waiting on.

GraphQL & REST APIs

Contract-first, versioned APIs designed for the teams that will consume them — documented, backward-compatible, and tested against the contract on every release.

Observability & tracing

Structured logs, metrics, and distributed traces instrumented from day one, with SLOs that define "healthy" numerically rather than by gut feel.

Load & chaos testing

Headroom proven before launch, not discovered after — load profiles that mirror reality and failure injection that verifies the graceful-degradation story actually holds.

04 — THE STACK, AND WHY

Rust

Memory-safe performance for the hot paths where latency and correctness both matter.

Go

Fast, boring, operable network services — the right default for most of the fleet.

Postgres

Correct, battle-tested persistence; exotic databases only where the workload earns them.

Kafka

The event backbone that keeps services decoupled and replayable.

05 — IN PRODUCTION

A regulated, ledger-grade platform built on this practice:

Fiat, crypto, and card issuance on one ledger — the regulated layers stay pluggable per market.

06 — COMMON QUESTIONS

Can you modernize our legacy systems?

Yes. We specialize in safely migrating monolithic systems into modular, composable architectures — often in place, without interrupting live operations.

How do you handle cybersecurity?

A Zero-Trust baseline: every interaction is continuously verified, and data is encrypted with AES-256 at rest and in transit.

Do we own the code and infrastructure?

Completely. Clean, documented, portable architecture with no vendor lock-in. You keep the keys.
