@caitlinaboudFAQ
Why should I choose Happy Vibes for software engineering?
When we team up to work together, we commit to your success, often going beyond contractual obligations to make your project shine. It's our core principle. We don't just follow instructions; we always bring our ideas to the table, and actively seek ways to boost your project with valuable suggestions.
We're not just another outsource company, we build long-term relationships. With most of our clients we work for years and it continues.

Does Happy Vibes use AI tools to code (Cursor, Claude, Copilot)?
We don't only use AI technologies, we actually build them. One of our own projects, Stroke, is a desktop app that helps people to train their own AI models (we call them digital twins) to solve the problem of AI and creativity.
What is the tech stack you use for projects?
We roll with any technologies – React.js, Node.js, Next.js, Convex, Cloudflare, and more. Actually, it's never about the tools. Our focus is thinking critically about the business goals and how to build solutions that solve problems. Based on that, we choose the tech stack that fits best.
Do you handle all stages of software engineering?
Absolutely. We handle research, design, development, and ongoing maintenance. Already have something built? We’re ready to take it from there.
What is the average budget you work with?
It really depends on the project. Smaller builds typically range from $10k to $25k, while more complex products usually start around $30k and can go higher.
We work in clear, fixed-price milestones—so you always know what you're paying for, with no surprises.

Can you work with tight timelines?
Yes, we can move fast and build emergently. In that case, we’ll assign more teammates to work on features in parallel.
If I want to change anything in between the project, is it possible?
Of course. That’s how successful software is actually built. You’ll get new input along the way, and we’re flexible enough to adapt and implement those changes as they come.
How will you keep me updated on the project progress?
We prefer fast, informal channels like Telegram or Discord to keep things moving quickly. Frequency depends on the project needs.
Do you offer post-launch support and maintenance?
Absolutely. We’re especially interested in what happens after launch. That’s when the real work begins. We focus on long-term partnerships and ongoing support to help your product grow over time. As said, with most of our clients we work for years and it continues.
