FAQs

Hiring JavaScript developers, answered.

Share your brief or repo. You get matched profiles, an engagement plan and a written cost inside two working days.

Request Developer Profiles

Share your brief or existing repo. Within 48 hours you get matched JavaScript developer profiles with live products they built, a suggested engagement model and a written monthly or project cost. Most clients start with a two-week paid trial sprint before scaling the team.

Yes. You can hire a dedicated JavaScript developer full-time on a monthly retainer, take a part-time senior from 40 hours a month for architecture and reviews, or run a fixed-scope full stack pod. There is no long-term lock-in beyond the trial sprint.

Yes. Our full stack JavaScript developers work across React or Next.js on the front end and Node.js, NestJS or Express on the backend, with PostgreSQL, MongoDB and Redis for data. One engineer can own a feature from UI to schema to deploy.

Both. New builds default to TypeScript for safer refactors and better editor tooling. For existing plain JavaScript codebases we can keep the current setup or run an incremental TypeScript migration in slices so releases never stop.

Our team overlaps at least four hours with US, UK, Europe, Middle East and APAC business hours, and daily standups run inside that window. Handover notes are written so work continues outside the overlap.

Cost depends on seniority and engagement model. You get a written monthly rate for dedicated developers or a fixed milestone cost for scoped projects — both quoted within two working days of the discovery call, with no hidden onboarding fees.
