How long does a typical project take?

Timelines vary by scope. A small web app takes 4-8 weeks, a medium full-stack project 2-4 months, and enterprise-grade systems 4-8 months. As a freelance developer, I provide a detailed timeline during the Discovery phase and keep you updated at every sprint.

Do you work with startups or only enterprises?

I work with everyone — from early-stage startups building their MVP to established enterprises modernizing their systems. As a freelance developer, my flexible engagement models adapt to your needs and budget. I'm especially passionate about helping startups launch their first product.

What happens after the project is launched?

Every project includes post-launch support (duration depends on the scope). I handle bug fixes, monitoring, and minor updates. For ongoing needs, I offer freelance retainer packages and dedicated hourly/monthly arrangements.

How do you ensure code quality?

Every line of code goes through peer code reviews, automated testing (unit + integration), linting, and security scans. I follow clean architecture principles and industry best practices. As a freelance developer, my reputation depends on the quality I deliver.

Can you work with our existing team?

Absolutely. I offer staff augmentation, pair programming, and consulting models where I integrate directly with your team. I adapt to your tools, processes, and communication channels. Many clients hire me as a freelance extension of their in-house team.

What technologies do you use?

I specialize in Java, Spring Boot, React, Next.js, TypeScript, PostgreSQL, Redis, Docker, Kubernetes, and Kafka. But I choose technologies based on what's best for your specific project, not one-size-fits-all.

How do I hire you as a freelance developer?

Simply reach out via the contact form or email. We'll start with a free 30-minute consultation to understand your project. I'll then provide a detailed proposal with timeline, cost, and approach. You can hire me for fixed-price projects or on an hourly/monthly basis.

What are your freelance rates?

Every project is unique, so I provide custom quotes based on scope, complexity, and timeline. I offer competitive freelance rates for startups and businesses of all sizes. Contact me for a free estimate — no obligation.

Do you offer ongoing freelance support and maintenance?

Yes! I offer flexible freelance retainer packages for ongoing development, maintenance, monitoring, and feature additions. Many of my clients maintain long-term freelance relationships for continuous product evolution.
