Web Development Questions & Answers

I focus exclusively on custom software development — websites, web apps, and SaaS built with React and Next.js. Design, branding, and marketing are outside my scope. If you need those services, I can recommend specialists.

I work as a solo full-stack developer and handle the entire build myself. You work directly with the person writing your code — one point of contact from start to finish.

Yes. I work with companies in Poland and international clients in the UK and US. Communication is in English or Polish, and Polish content is reviewed with my wife to ensure natural language and accuracy.

I start by defining requirements and technical architecture, then move into iterative development with regular checkpoints. Features are built and tested as we go, with adjustments based on your feedback.

Simple business websites take 3-5 weeks. SaaS platforms or custom e-commerce systems typically take 8-12 weeks, depending on integrations, database complexity, and feature requirements.

Direct communication via email, Slack, or calls—whatever works for you. Weekly check-ins keep you updated on progress, blockers, and next steps. No unnecessary meetings or status reports.

Yes. Projects start with a 30-50% deposit, with the remainder paid in milestones or at delivery. This keeps timelines predictable and protects both sides.

I accept bank transfers (SWIFT/SEPA for international clients) and online payment platforms. All transactions are straightforward and compliant with EU regulations.

Yes, for larger projects. Payments are split into clear milestones tied to delivered work, so you're paying for real progress.

Yes, if the codebase is reasonably maintained and documented. I'll review it first and tell you honestly whether it makes sense to extend it, refactor parts, or start fresh.

Yes. I handle production deployment, environment configuration, and performance optimization. Your application launches stable, monitored, and ready for real users—not just pushed live and forgotten.

I follow modern security practices for authentication and data handling. Server-side rendering, optimized images, and proper caching are built in by default. Core Web Vitals and load times are treated as requirements, not extras.

AI costs are managed through caching, request limits, and only calling AI when it adds real value. Common results can be reused instead of regenerated, which significantly reduces usage. I also design features so costs scale with business value, not background noise.

Data sent to AI providers is processed by external services like OpenAI or Anthropic, so they technically see the input. I minimize what is sent, avoid unnecessary personal data, and follow provider privacy options where available. If strict data control is required, we discuss alternatives or limits before building anything.

AI is probabilistic, not deterministic, so it will sometimes be wrong or inconsistent. That's why I always build fallbacks, validation, and clear UI states for uncertain results. You should expect AI to assist and speed things up, not to be 100% correct.

The best provider depends on the task, cost profile, and reliability requirements. Some models are better at structured classification, others at longer reasoning or safer outputs. I usually test providers on your specific use case and choose based on results, not brand names.

Yes. I offer maintenance and development plans covering updates, bug fixes, performance improvements, and new features as your product evolves.

Yes. I provide documentation and walkthroughs so your team understands the system and can manage content or basic operations confidently.

New features can be added as separate projects or as part of a maintenance agreement. Clean code means extending functionality is usually straightforward and predictable.
