Your AI-generated code got you to v1. I'll get you to production.
Take vibe-coded web and mobile apps — built with Cursor, Bolt, Lovable, or Replit Agent — and rebuild them into production-grade software without starting from scratch.

Security issues fixed
Vibe coding tools like Cursor, Bolt, Lovable, and Replit Agent are great for prototyping. But the code they produce? Spaghetti architecture, no error handling, security holes, and performance bottlenecks that surface the moment real users show up.
I take vibe-coded web and mobile apps and rebuild them into production-grade software without starting from scratch. You keep your features and momentum. I fix the foundation underneath.
Every engagement starts with a full codebase audit and a prioritised report of what is broken, what is risky, and what can wait. Then we triage the critical path — what needs fixing before you can scale or raise — and refactor iteratively, shipping improvements you can test along the way. You get a clean, documented codebase that your next developer or AI tool can actually work with.
Restructure tangled codebases into clean, maintainable modules. Proper separation of concerns, consistent patterns, and scalable folder structure that your team can actually navigate.
Patch exposed API keys, missing auth checks, SQL injection risks, unvalidated inputs, and insecure dependencies. OWASP Top 10 remediation with a comprehensive security audit report.
Fix N+1 queries, memory leaks, unnecessary re-renders, slow API calls, and bundle size bloat. Lighthouse score improvement, Core Web Vitals optimisation, and measurable before-and-after benchmarks.
Normalise schemas, add proper indexing, fix broken migrations, eliminate redundant tables, and establish migration best practices. Query performance optimisation and data integrity verification.
Set up CI/CD, environment management, proper staging and production separation, infrastructure as code, and deployment automation. No more manual deploys or environment drift.
Add TypeScript types, error boundaries, structured logging, input validation, and targeted test coverage where it matters most. Establish coding standards and automated quality gates.
Full codebase review covering architecture, security, performance, database, deployment, and code quality. Delivered as a prioritised report with severity ratings — what is broken, what is risky, and what can wait.
We agree on the critical path: what needs fixing before you can scale, raise funding, or onboard more users. Scope the rescue into manageable phases with clear success criteria and timeline.
Iterative refactoring and hardening of the codebase. Each phase ships working improvements you can deploy and test along the way — no long-running branches or rewrite-in-a-black-box approaches.
Final documentation, architecture diagrams, deployment runbooks, and coding standards. A handoff walkthrough so your team or future AI tools can work effectively with the rescued codebase.
Kismaa's initial prototype was built rapidly with AI coding tools to validate market demand. It worked well in demos but had no error handling, exposed API keys in client-side code, unoptimised database queries that timed out under load, and a deployment process that required manual server access.
We ran a 3-week codebase rescue: hardcoded secrets were moved to environment variables with a secrets manager, database queries were optimised with proper indexing and connection pooling, the frontend was restructured into a component hierarchy with error boundaries, and a CI/CD pipeline was set up with automated testing and staging/production environments.

"App Corp delivered a production-ready AI platform in 11 weeks that our internal team estimated would take 9 months. The architecture is clean, the docs are thorough, and the product works exactly as specified."
