Problem Statement
Callesto International required multiple senior-level .NET + Angular developers to support ongoing product and technology initiatives. The roles demanded experienced professionals capable of handling complex development work, delivering production-ready features, and aligning with the company’s fast-paced environment.
With several simultaneous openings and an urgent need to maintain delivery momentum, Callesto International needed a partner able to source and evaluate qualified candidates quickly while ensuring a strong technical and cultural fit.
Solutions
Benchkart utilised its bench resource ecosystem to identify senior .NET + Angular developers aligned with the client’s technical expectations. Collaborating with a leading IT staff augmentation partner, Benchkart sourced developers with the required depth in backend and frontend engineering.
Through structured project management, Benchkart oversaw the full evaluation and onboarding flow coordinating between Callesto International and the partner agency to ensure clarity, timely communication, and smooth deployment. This approach allowed the client team to remain focused on product development while Benchkart handled the end-to-end staffing process.
The curated approach ensured that only experienced, technically capable profiles were shared, giving the client confidence in the consistency and quality of the shortlisted candidates.
Outcome
Benchkart successfully deployed four experienced .NET + Angular developers, each aligned with the client’s project requirements. The selected developers are now contributing to ongoing initiatives, strengthening the company’s ability to deliver stable, high-quality technology solutions.
The engagement provided Callesto International with dependable senior resources, improved delivery continuity, and reinforced their confidence in using Benchkart for ongoing and future flexi staffing requirements.
