Pyzen Technologies provided us with a reliable web scraping and data automation solution for our business research needs. Their team understood the requirement clearly, managed the data extraction process professionally, and delivered accurate data on time. We were impressed with their communication, technical knowledge, and support.
I approached to Shivansh for the development of an AI/ML-based high-throughput tool in the healthcare domain. Their technical team is highly knowledgeable, responsive, and committed to delivering quality solutions. The best part was they scheduled many time to time meetings to show the development of work and take client opinion and feedback on each step. Highly highly recommend

Do you take over existing codebases?
Yes. We start with a code and architecture review, stabilise what is there and then improve it release by release.
Who owns the source code?
You do. Code, documentation and credentials are handed over under the contract, and every engagement is covered by an NDA.
