AI Coding Assistants: Real Productivity Gains, Hidden Costs and How We Use Them

Short answer

AI coding assistants speed up boilerplate, tests, refactoring and documentation, which can reduce effort on many tasks. But review, architecture, security and debugging still need skilled engineers, and unreviewed generated code adds maintenance cost later. The savings are real when engineers direct the tools and keep quality checks in place.

Where they help

  • Scaffolding screens, API clients and CRUD
  • Writing and expanding tests
  • Refactoring and renaming
  • Explaining unfamiliar code
  • Drafting documentation and migration scripts

Where they need supervision

  • Authentication and authorisation
  • Data models and migrations
  • Payment and personal-data flows
  • Performance-critical paths
  • Anything touching secrets or production systems

Hidden costs

CostHow it shows up
Review timeEngineers must read and understand generated code
ReworkPlausible but wrong code found late
Security fixesMissing access checks or exposed secrets
MaintenanceInconsistent patterns across files
Tool and API spendSubscriptions and usage charges

How we use them

  1. Engineers write specs and plans; tools draft code.
  2. Everything is reviewed, tested and scanned.
  3. Security-sensitive parts are written or checked by senior engineers.
  4. We pass the time savings on through fixed-price packages such as a full ERP with mobile app delivered for a manufacturing plant at $650.

Frequently asked questions

Do AI assistants make projects cheaper?

Often for well-defined work, but only if review and testing are kept; otherwise costs return as rework.

Can a non-developer replace an engineer with AI tools?

For prototypes, sometimes; for production systems you still need engineering judgement.

Is AI-generated code lower quality?

It can be, which is why review, tests and security checks matter.
