Full-Stack Development FAQ
What technologies do you specialize in?
I specialize in the modern JavaScript/TypeScript ecosystem: NestJS for backend, Next.js and React for frontend, PostgreSQL for databases, and Docker/AWS for deployment. This stack allows me to build scalable, maintainable applications efficiently.
Can you work with my existing codebase?
Absolutely. I regularly join existing projects to add features, fix bugs, or improve architecture. I start with a codebase audit to understand the current state, then provide recommendations and implement changes incrementally without disrupting your team.
How do you ensure code quality?
I follow industry best practices: TypeScript for type safety, comprehensive testing (unit, integration, e2e), code reviews, CI/CD pipelines with automated checks, and clear documentation. My code is built to be maintained by your team long after the engagement ends.
What's your experience with scaling applications?
I've built systems handling millions of records and high traffic loads. This includes database optimization with materialized views, caching strategies with Redis, horizontal scaling with load balancers, and performance monitoring. I recently optimized queries from 5s to 200ms on a 4.2M record database.
Do you handle both frontend and backend?
Yes, I'm a true full-stack developer. I can build your entire application from database schema to polished UI, or focus on just the backend or frontend depending on your needs. This flexibility means fewer handoffs and faster delivery.
