This engagement creates value fastest for teams like these.
Teams shipping under delivery pressure
Engineering organizations that need backend, mobile, DevOps, or DevSecOps support without losing security rigor.
CTOs and platform leads
Leads that need architecture, release, and operations support tied back to offensive validation priorities.
Programs that want build plus hardening
Buyers that do not want a separate delivery vendor and a separate security vendor working against each other.
Platform & scope
Delivery risks
Outcomes
Evidence standard
Proof you can inspect. Boundaries you can plan around.
Every engagement is bounded by written authorization, evidence handling, and a clear handoff. These are the defaults; the signed scope can tighten them.
Evidence you receive
- Architecture, code, or configuration decisions tied to the agreed scope.
- Reviewable changes, operational notes, and handoff documentation.
- Security tradeoffs, release risks, and hardening priorities made explicit.
- Verification steps for the delivered work.
Explicit exclusions
- A penetration test report unless testing is separately scoped.
- Production changes without an approved change window and rollback path.
- Compliance certification or ongoing 24/7 support unless contracted.
- Ownership transfer of third-party or pre-existing intellectual property.
A mobile delivery motion aligned with product and engineering cadence.
Platform and product decision
We align on native iOS/Android versus React Native or Flutter based on team shape, product constraints, and delivery speed.
Implementation and integration
Mobile flows, API connections, session models, failure handling, and release-quality concerns are built with production use in mind.
Release readiness and handover
Delivery becomes sustainable through release standards, maintenance notes, observability, and clear team handover.
The questions buyers want answered early.
How does this relate to pentest work?+
Do you work inside an existing engineering roadmap?+
What do teams get besides code or configuration?+
We do not treat mobile delivery as screen implementation alone.
Session models, API trust, device behavior, failure surfaces, and release cadence are treated as one system so the team gets a maintainable mobile product, not just a working demo.
Backend and mobile delivery stay aligned as one system.
The mobile client, backend contracts, release preparation, and operating notes are shaped together so product teams encounter fewer surprises later.

Critical Authentication Bypass via JWT Signature Verification Disabled in yargi-mcp
yargi-mcp decodes Clerk JWT tokens with signature verification disabled, enabling authentication bypass, forged identities, and arbitrary scope escalation.
Let’s scope this work against the surface that matters most.
Whether this starts as a pilot, a single application, a critical API, an AI agent flow, or a wider program, we start from the highest-impact surface.
