Why Witarist

The fastest path to a vetted Kolkata developer in Kolkata

  • 48-hour shortlist

    Vetted profiles in your inbox in two days, not two weeks.

  • Pre-vetted at four stages

    Every developer clears fundamentals, framework depth, system design, and a live coding round.

    Flat monthly retainer per profile — no 20% placement charges, no platform markup.

  • NDA + IP transfer day one

    Standard mutual NDA and complete IP assignment to your company before work starts.

  • Two-week replacement window

    If the engagement isn't working in the first 14 days, we re-shortlist at no cost.

FAQ

Frequently asked questions

How quickly can I hire Kolkata developers from Witarist?

Most clients receive a vetted Kolkata developer shortlist based in Kolkata within 48 hours of sharing requirements. After interviews, the selected developer typically onboards within the same week with NDA and IP assignment in place.

Are your Kolkata developers pre-vetted?

Yes. Every Kolkata developer in our network goes through a multi-stage screen covering Kolkata fundamentals, framework-level depth, system design, and a live coding round. We only present candidates who have cleared all four stages.

How much does a senior Kolkata developer cost per month?

Monthly pricing depends on seniority, exclusivity, and engagement length. Mid-level Kolkata engineers typically fall in the most cost-efficient bracket of Indian staff augmentation, and we share a transparent monthly retainer per profile — no hourly billing surprises.

Do Kolkata developers come with NDA + IP transfer?

Yes. Every engagement includes a mutual NDA and complete IP assignment to your company before the developer starts work. All code, designs, and deliverables produced during the engagement are yours from day one.

Can I hire Kolkata developers full-time or part-time?

Both options are available. Full-time (160 hrs/month) is most common, but we also support dedicated part-time arrangements (80 hrs/month) for Kolkata in Kolkata when the scope is smaller. There are no recruiting fees in either model.

Are your Kolkata developers available for remote work?

Yes — most of our Kolkata developers based in Kolkata work remotely with overlap to your timezone. We also support hybrid and onsite arrangements when you have a physical office or compliance requirement.

How experienced are your Kolkata developers?

Our Kolkata talent network spans 2-12+ years of experience. We share the full background, code samples, and project history for each candidate so you can match seniority to your needs before any interview.

Is there a trial period for the Kolkata developer?

Yes. We offer a no-questions-asked replacement window in the first two weeks of the engagement. If the Kolkata developer isn't the right fit, we'll re-shortlist at no extra cost — you only pay when you're satisfied.
