Fixes keep causing new bugs
The same issue returns, code is hard to follow and every change feels risky. You need a clear diagnosis and tests around the flows that matter.
ENGINEERING SPRINT / BY KNOWIT
AI App Rescue Stabilize, secure and prepare your AI-built app for real users.
Built with Cursor, Lovable, Replit or another AI tool? Keep your momentum. Our engineers audit the code, fix the agreed priorities and put the foundations in place for a controlled production release.
Two-week sprintEngineer-led deliveryYour code. Your infrastructure.
01 / WHEN THE DEMO STOPS BEING ENOUGH
A working demo is a start. A dependable product is the next step.
You have validated an idea. Now you need to know what can break, what needs protecting and what it will take to run the product with real customers.
Data access is difficult to trust
User permissions, database policies and secrets need a deliberate review before sensitive data and customer accounts enter the system.
Running costs are unpredictable
AI calls, database queries and cloud resources need limits, visibility and an operating model you can understand.
02 / WHAT WE WORK ON
Engineering work. Concrete deliverables.
We agree a focused scope after reviewing the prototype. The sprint combines diagnosis with hands-on fixes, verification and a practical handover.
Code & architecture audit
Map the application, dependencies and critical user journeys. Identify fragile components and prioritize issues by impact.
You receive: a prioritized findings report and sprint backlog.
Targeted refactoring & tests
Refactor the agreed problem areas, fix reproducible defects and add regression tests around the core flows.
You receive: reviewed code changes and repeatable checks.
Authentication, permissions & data
Review sign-in, roles and tenant isolation. Fix agreed authorization gaps and test database access policies, including RLS where applicable.
You receive: tested access rules and documented decisions.
Secrets, APIs & spend controls
Identify exposed credentials, coordinate rotation and move secrets to the right environment. Add scoped rate limits, usage controls and alerts.
You receive: safer configuration and visibility into usage.
Containerization & release setup
Create a reproducible Docker setup for the application components in scope. Document environment configuration, deployment and rollback.
You receive: a containerized build and release runbook.
Observability & handover
Set up the agreed health checks, logs and error monitoring. Review recovery needs and walk your team through the system and remaining risks.
You receive: operating instructions and a release-readiness review.
03 / THE TWO-WEEK PLAN
A clear sequence. One focused sprint.
Ten working days of engineering, starting once the scope, access and working environment are ready.
DAYS 01–02
Understand & prioritize
Reproduce the key issues, review the code and access model, and agree the changes and acceptance checks.
DAYS 03–05
Stabilize the core
Refactor the highest-impact areas, fix agreed defects and add tests for critical user journeys.
DAYS 06–08
Harden & package
Implement agreed security and usage controls, containerize the application and prepare the release workflow.
DAYS 09–10
Verify & hand over
Run the checks, document deployment and recovery steps, and review whether the agreed release criteria are met.
The sprint ends with working changes, evidence of what was tested and an explicit list of remaining risks. Release happens when the agreed checks pass; larger rebuilds need a separate scope.
04 / IS THIS THE RIGHT NEXT STEP?
Bring what you have. We’ll assess the next step.
A good fit for the sprint
- An AI-built web app or MVP with a working prototype.
- A founder or small team preparing for first customers or a more reliable launch.
- An existing codebase you can provide access to, with permission to change it.
- A focused set of problems that can be prioritized for two weeks.
Before we start
We review the stack, access requirements and launch goals together. You receive an agreed scope and acceptance criteria before implementation begins.
Formal penetration testing, compliance certification, a full rebuild and ongoing operations are separate engagements. If an active breach is suspected, we assess the immediate response first.
THE TEAM BEHIND THE SPRINT
Business software, beyond the demo.
KnowIT builds business applications, data platforms and operational systems. Our work includes field-service software, asset management and ML-driven logistics. We bring that engineering experience to your prototype.
Questions before the handover?
Is this the same as a code audit?
The audit is the starting point. The agreed sprint also includes implementation, tests, containerization and handover. The findings define the priorities; they are not the only deliverable.
Do I have to move away from Cursor, Lovable or Replit?
The tool you used is not the issue. We review the exported code, integrations and deployment options. We keep what works and recommend changes where the current setup limits security, reliability or ownership.
Will you rewrite the entire application?
The aim is to preserve useful work and make focused improvements. If the architecture needs a larger rebuild, we explain why and agree the next step before expanding the scope.
What if the prototype is not ready to launch after two weeks?
You receive the completed changes, test results and a clear list of remaining blockers. A two-week sprint is a defined engineering engagement, not a promise that every prototype can safely launch on day ten.
What should I share in the first enquiry?
Tell us what the app does, which tools and services it uses, what is going wrong and your intended launch date. A public demo link is useful. Source access and any sensitive information are arranged separately; do not put credentials or customer data in the contact form.
Can you help after the sprint?
We can discuss a separate follow-on scope for remaining development, maintenance or operational support. You keep the code, documentation and access to your own infrastructure.
YOUR NEXT STEP
Tell us what you built.
Share your prototype, the main blocker and what you want to launch. We’ll discuss whether the sprint fits and what to review first.
Discuss your prototypeStart with a short description or public demo. We’ll arrange code access separately.
