4CTech / Application engineering

Get your application unstuck. Get it shipped.

Broken builds, difficult integrations, unfinished features, or a release that never quite makes it out the door. Senior engineering help with clear scope, documented findings, and a practical path to production.

iOS, Apple Watch companion apps, web apps, build pipelines, integration and release troubleshooting.

Defined engagements

Three ways to move forward.

Each engagement begins with a written scope and acceptance criteria. Pricing below covers standard cases; unusual complexity is quoted separately before work begins.

01 / Diagnose

Engineering diagnostic

$149

For a problem you can describe but cannot confidently isolate.

  • Up to 60 minutes of technical review
  • Reproduction and environment review where feasible
  • Written findings, risks, and next-step recommendation
  • Credit toward an approved repair engagement within 14 days

Deliverable: concise diagnostic brief.

03 / Release

Release readiness & submission

From $599

For an app that works but needs a disciplined route to distribution.

  • Build, signing, and configuration review
  • Release checklist and smoke-test matrix
  • Archive/distribution guidance or hands-on assistance
  • Documented blockers and handoff

Deliverable: release package/checklist. Store acceptance is not guaranteed.

Plan a release

Client retains ownership of source code and developer accounts. App Store fees, third-party subscriptions, device procurement, new features and extensive refactors are outside standard packages unless expressly included.

Working method

Senior-level engineering, scaled to a focused problem.

Every engagement uses the same fundamentals that make large production systems predictable—without unnecessary ceremony.

Intake

Clarify symptoms, business impact, technical ownership, dependencies and access requirements.

Baseline

Capture build state, reproducibility, and known constraints. Identify risk before making changes.

Implement

Work against agreed acceptance criteria in a reviewable branch or patch.

Validate

Deliver test evidence, residual issues, deployment notes and next actions.

A practical fit

When the project is almost there—but not quite.

Especially useful for independent founders, small product teams and businesses with an existing codebase that needs experienced attention before launch.

  • Build failures and signing/configuration issues
  • TestFlight and App Store release preparation
  • Unreliable data flow or integration defects
  • Web or mobile feature stabilization
  • Technical review before funding a larger rebuild
Confidential work stays confidential.

Code access is granted only after agreement on scope and confidentiality. Use least-privilege access, staging/test credentials where practical, and revoke temporary access at handoff.

This service is performed on client-owned or properly licensed software only.

Questions

Clear expectations from the start.

Do you guarantee a fix?

No. Diagnostics identify the most supportable remediation path. Repair estimates are provided only when scope and feasibility are sufficiently clear.

Do you need access to production?

Usually not. We start with a code review, reproducible environment, and sanitized test data whenever possible.

Can you guarantee App Store approval?

No. Apple's review decisions remain Apple's. The engagement addresses build/distribution readiness and identified submission requirements.
