How We Ensure Successful Cooperation
On-demand team adjustment
Whenever you request services of a dedicated JavaScript team or augment your existing team with our JavaScript experts for hire, ScienceSoft takes on responsibility to scale the teams up or down in just 1–2 days if required.
Transparency of progress and results
First of all, this includes thorough documentation of all processes and project details, which is consistently shared you. In case of a dedicated team cooperation model, we use such KPIs as cycle time, team velocity, and deployment frequency to make sure our JS developers always show the highest performance. We also give you access to our reporting tools, where you can track project progress and task completion anytime.
Highly motivated employees
ScienceSoft takes care to motivate and provide professional growth possibilities for JavaScript developers to ensure their skills don’t get rusty. We regularly organize internal training sessions and encourage our developers to participate in tech conferences.
Hire JavaScript Developers: In-house vs. Outsourcing
- Building a solid team of 3-5 JavaScript developers can take up to 8-10 months, on average. By turning to a vendor, you get a team of this or larger size in a single week and launch your project faster.
- Financial compensation for in-house employment includes payroll taxes. When you work with a vendor, you only make payments according to the T&M model by hourly rate, while the vendor handles taxes themselves.
- When you hire JavaScript developers in-house, you have long-term legal obligations that you can’t easily abandon. In vendor outsourcing, you can put the cooperation on hold or cancel it with a 1-month notice.
