Success stories

Challenge

A developer was struggling with React hooks in a new project. The codebase was moving from class components to functional components and hooks, and they were behind on deadlines with unclear patterns for state and effects.

Solution

• Daily 2-hour pair programming sessions focused on hooks and refactoring
• Code review and refactoring of existing components to use hooks consistently
• Best practices for useEffect, useMemo, and custom hooks

Results

• Project delivered 2 weeks ahead of schedule
• Developer gained confidence and could extend the pattern to new features
• Received positive feedback and took on more ownership within 3 months

Challenge

A backend developer was assigned to a new microservice written in Node.js and Express. They had strong Java/Spring experience but limited Node.js exposure and needed to ship features without delaying the team.

Solution

• Structured walkthrough of Node.js and Express patterns compared to Spring
• API design and database layer (MongoDB) with best practices
• Debugging and testing (Jest) so they could work independently

Results

• Delivered first feature within 2 weeks
• Became the go-to person for that service within 2 months
• Transitioned to full-time Node.js role on the team

Challenge

A developer joined a large Angular project using NgRx. They found the reactive patterns and store structure confusing and were slow to implement new features without introducing bugs.

Solution

• NgRx fundamentals: actions, reducers, effects, and selectors
• Pair programming on real features to apply the patterns
• Code reviews and refactoring of their first PRs

Results

• Confidently implemented a new feature module within 3 weeks
• Reduced code review cycles after understanding the patterns
• Able to onboard another team member later
