Everything you need to know.
Common questions before we get started.
Can't find what you're looking for? Reach out directly.
Project-based suits a clearly-defined build with a fixed scope and price. Dedicated developer ($1,200–$1,500/mo) is best for ongoing work where you want a full-time engineer embedded in your team. Hourly (from $14/hr) fits smaller tasks or ad-hoc support. We'll recommend the right fit on a free discovery call.

Hourly (from $14/hr) fits smaller tasks or ad-hoc support. We'll recommend the right fit on a free discovery call.
What happens if the project scope changes?
We flag scope changes before any work starts no silent overages. For project-based engagements we'll quote the change up front so you decide; on dedicated or hourly plans, new work simply rolls into the ongoing schedule. You're always in control of the budget.
Are there any hidden fees?
None. The price we agree on is the price you pay. No setup fees, no surprise add-ons, no markup on third-party services we pass those through at cost and tell you about them in advance.
How does billing and payment work?
Project-based work is billed against agreed milestones, so you pay as deliverables land. Dedicated developer plans are billed monthly, and hourly work is invoiced with a transparent weekly time report. We accept international payments and can work with your preferred method.
Can I switch or scale my plan later?
Yes there's no lock-in. Start hourly and move to a dedicated developer as the work grows, or scale your team up and down month to month. We'll adjust the engagement to match where your product is.
Do you provide post-launch support?
Absolutely. We offer ongoing maintenance, bug fixes, performance monitoring, and feature iterations after launch. Dedicated developer plans include continuous support as part of the package; project-based builds come with a post-launch support window.
