How quickly can I hire a OpenAI API developer from Krapton?

Within 24 hours of the initial call. We keep a bench of pre-vetted OpenAI API engineers, so once you confirm the brief we line up two or three shortlisted CVs within a business day and can onboard the selected developer within two.

How much does it cost to hire a dedicated OpenAI API developer from India?

Blended hourly rates for senior OpenAI API engineers typically fall in the $30–$60 USD range depending on seniority and engagement length — roughly 50–70% cheaper than equivalent talent in the US or UK, with no loss of code quality. Dedicated developers are billed monthly with no lock-in.

Are your OpenAI API developers full-time employees or freelancers?

Every OpenAI API developer you hire through Krapton is a full-time, in-house engineer — we never subcontract to freelancers or agencies. That means consistent code quality, signed NDAs, and a single point of accountability for your project.

Can I hire remote and offshore OpenAI API developers who work in my timezone?

Yes. Our New Delhi team works in IST and overlaps 4–6 hours per day with PST, EST, GMT, CET and AEST clients for live standups, pairing and code review. You get the cost advantage of offshore OpenAI API developers with enough real-time overlap to feel like an in-house team.

Who owns the code and IP my OpenAI API developers write?

You do — 100%. IP assignment and confidentiality are covered by the contract and a free NDA on request. All code lives in your repositories, on your infrastructure, under your accounts from day one.

What if a OpenAI API developer is not the right fit?

You get a free replacement guarantee for the first 30 days. If your developer is not delivering to expectations in that window, we replace them at no cost within five business days, and you only pay for hours worked by the original engineer.

Can you provide a whole OpenAI API team, not just one developer?

Yes. Many clients start with one OpenAI API developer and scale into a pod — for example a couple of OpenAI API engineers, a QA engineer and a part-time DevOps or UI/UX specialist — coordinated by a delivery lead. You scale the team up or down month by month.

Do you work with both startups and enterprises?

Both. Startups hire OpenAI API developers from Krapton to ship an MVP fast on a lean budget; enterprises use us for dedicated capacity, modernization and overflow delivery with NDAs, security controls and clear reporting. We tailor the engagement model and process to each.

Which engagement models do you offer for hiring OpenAI API developers?

Three: (1) a dedicated full-time developer billed monthly — best for ongoing products; (2) hourly time-and-materials — best for research or variable-load work; (3) fixed-price milestones — best for well-scoped builds. We recommend the right fit after a 30-minute discovery call.
