Mobile, backend, and security engineering for product surfaces that break under pressure

We join active builds, fix brittle workflows in code, and harden the boundaries most likely to fail in production.

Who we help

Who we help

A fast fit check before you go deeper.

Good fit

  • Auth, recovery, or session behavior drifting between app and backend.
  • API authorization regressions that keep reappearing during releases.
  • Teams that need hands-on fixes, not findings-only output.

Not a fit

  • Compliance-only paperwork without an engineering owner.
  • Open-ended staffing requests with no defined system surface.
  • Unauthorized assessment requests or unclear remediation ownership.

Core services

Core services

Four primary lanes we start from most often.

Mobile engineering

Stabilize iOS and Android clients when releases feel risky or fragile.

Backend and API hardening

Repair authorization drift and brittle service boundaries under load.

Auth and session security

Fix login, recovery, and account actions where control assumptions break.

Security review

Focused review before a launch or high-impact change, including release integrity.

Proof

Recent anonymized outcomes

Technical buyers usually want evidence early. These are short snapshots from delivery work.

Client type

Launch-stage consumer product

Risky workflow

Recovery and session invalidation across iOS, Android, and backend.

What changed

Token lifecycle and backend invalidation were reworked end to end.

Result

Launch readiness improved with fewer account-state surprises.

Client type

Live account platform

Risky workflow

Object-level authorization across service boundaries.

What changed

Ambiguous checks were replaced with consistent backend enforcement paths.

Result

Sensitive API behavior became predictable during high traffic windows.

Client type

Mobile + backend delivery team

Risky workflow

Go or no-go decisions with weak provenance and rollback confidence.

What changed

Artifact trust checks and rollback controls were tightened.

Result

Release decisions became clearer and rollback risk dropped.

Engagement shapes

Common engagement shapes

Clear starting points with tight scope.

Advisory Sprint

Best for

One fragile workflow needs immediate triage and sequencing.

Output

Prioritized fixes and a concrete execution plan.

Security Review

Best for

Pre-launch review or post-incident analysis with real risk.

Output

Findings ranked by impact, with remediation criteria.

Implementation Support

Best for

Known risk that needs hands-on fixes to ship safely.

Output

Code and config changes across app and backend.

Retained Technical Partner

Best for

Recurring risky changes across auth, API, and release paths.

Output

Ongoing senior review and implementation support.

Process

What happens next

Simple process. No long pre-sale choreography.
