What engineering leads get from an Infoloop JavaScript developer
Experienced developers, your existing workflow and a rate agreed up front.
Two offices, one delivery team
Our JavaScript developers work from the head office in Surat, India, and join your team remotely. The Dover, Delaware office serves US clients.
Your workflow, not a parallel one
Your repository, your issue tracker and your code review standards. No separate vendor process runs alongside your own.
Pricing agreed before onboarding
Scope, timeline, rate and an estimate are agreed in writing before development begins. A clear scope gets a fixed price, and changing work is billed hourly.
Done means deployed
A task is complete when it is released and working for real customers. Merged code that has not shipped is still in progress.
Direct access to the developer
You work with the engineer writing the code, not an account manager relaying messages. Technical questions go straight to the person who owns the task.
Hiring process
From first call to first merged pull request
Four steps from an introductory call to a developer contributing in your sprint.
01Half-hour scoping call
You describe the codebase, the blocked work and the current maintainers. The call is free, and we confirm on it whether the work is a good fit.
02Written scope and pricing
We document the scope, the timeline and the cost before anyone starts. Open-ended work is billed hourly against an agreed estimate.
03Interview and onboarding
You interview every developer before they start. They join your repositories, your issue tracker and your daily stand-up. A reviewer from your team approves every change before release.
04Handover or ongoing support
Either option is standard: your team takes over with documentation and a walkthrough, or the same developer continues on a monthly support plan.

Engagement models and contract terms
Three ways to engage a JavaScript developer. Each one starts with a written agreement.
- Scope a project
Fixed-scope project
- Fixed price
- End date
One defined deliverable: an API integration, a rebuilt module or a migration off legacy code. Priced and scheduled in writing, then handed over or moved to monthly support.
- Interview a developer
Dedicated developer
- Hourly or monthly
- Onboarding in 1 to 2 weeks
A dedicated developer joins your team for an agreed term, billed hourly or monthly. They work in your tools and your backlog. You interview them first, and after the initial term the contract continues month to month.
- Discuss hourly work
Hourly work for changing scope
- Time and materials
Hourly billing suits work whose scope will change, such as ongoing improvements, support and discovery. The rate and an estimate are agreed in writing first. Support covers monitoring, fixes within an agreed response time and a monthly report.
What our clients say
They shipped our support agent in five weeks and it has run ever since. Response time dropped from hours to two minutes.

FAQs
Questions engineering leads ask before hiring JavaScript developers
Direct answers. Anything else, raise it on the scoping call.
What does a dedicated JavaScript developer cost per month?
A dedicated developer is billed hourly or monthly. The rate depends on seniority and the scope of ownership. The rate and an estimate are agreed in writing before onboarding. A fixed-scope project has one fixed price instead.
How fast can a JavaScript developer start?
Usually within 1 to 2 weeks of signing the agreement. Repository access, a security review on your side or an open architecture decision can delay that. On the scoping call, we list every prerequisite for day one.
What does a JavaScript developer do on a website?
They develop everything that responds in the browser: navigation, form validation, running totals and data that loads without a page refresh. Our developers also write server-side code in Node.js and mobile applications in React Native, with one language across all three layers.
Dedicated developer or freelancer: which should we hire?
A dedicated developer works in your team for an agreed term, inside your tools and your daily stand-up. One named engineer is accountable for delivery. A freelancer usually completes one task and moves on. Choose dedicated for ongoing development and a freelancer for a single small task.
Can your developers work on a legacy JavaScript codebase?
Yes. We audit the existing code and document how it behaves today. Then we ship small, incremental releases, so nothing depends on a complete rebuild. If replacement costs less than repair, we say so and price both options.
What happens after the work reaches production?
You choose, and both options are standard. Your team can take over with documentation, a walkthrough and code another engineer can maintain. Or the same developer continues on a monthly support plan, with a notice period in the contract.
