Consulting — API management · Platform engineering · GitOps

Your APIs, governed as code.

STOA Labs helps enterprises and financial institutions modernize their API gateways: zero-downtime migrations, Git-driven lifecycle, verifiable security. Every claim is backed by a reproducible test suite — never by a promise.

Services

Four practices, one common thread: proof.

We work where API management meets production: heterogeneous gateways, regulated environments, zero tolerance for downtime.

API gateway migration & modernization

Audit, exit or upgrade strategy, archive-based promotion, overlap cutover — with no service interruption.

GitOps API lifecycle

Git as the source of truth, multi-environment promotion dev → prod, governance enforced at deploy time, proven rollback.

API security & identity

Secrets out of the codebase (Vault), end-to-end OAuth2/OIDC, zero-downtime credential rotation, per-user identity down to the pipeline.

Multi-gateway observability

Unified transaction analytics across heterogeneous gateways, trace-level correlation, audit-ready dashboards.

Track record

Proof before promise.

Our clients operate in regulated industries: their names stay confidential. The results are measured — every engagement ends with a reproducible verification suite, delivered with the code.

Financial institution — Europe 0 downtime

Archive-based API promotion across segmented gateways

Overlap-based API version rollout on webMethods, validated three consecutive times under continuous traffic — zero dropped calls.

✓ 22/22 automated checks
Enterprise — services 4 env.

GitOps promotion chain dev → staging → UAT → prod

Manual promotion replaced by a pipeline-driven Git chain: version pinning, ITSM gate, one-command rollback.

✓ 19/19 automated checks
Regulated industry — Europe 100 %

Secrets out of Git, per-user identity end to end

Gateway and CI credentials read at runtime from Vault; every pipeline action traced to a named user, not a service account.

✓ 24/24 automated checks

Open source

Our method is public. It's the STOA platform.

Rather than describing how we work, we publish it: STOA is an open-source API management platform — control plane, developer portal, high-performance Rust gateway and CLI. The code we write for clients follows the same standards.

stoa Monorepo — control-plane API, console, Rust gateway
stoactl kubectl-style CLI for the platform
stoa-infra Terraform, Ansible, Helm — infrastructure as code
stoa-quickstart Self-hosted Docker Compose in one command
