Master Data Sanitization Portal | JARVIS
https://jarvis.lilacinsights.comLilac insights is one of India's biggest genetics counseling companies. They have customer data that keeps updating and changing, but since the system is on-premise and not accessible to the sales team, the information collected is outdated.
They need some way to update the customer data with minimum disturbance to the ongoing reports. The information must be up-to-date because this contains fields like credit limit and finance details.

Patient Management System | Medimetry
Medimetry is an online teleconsultation platform that connects patients to doctors who primarily deal with chronic diseases.
They needed a platform to store patients' health and medical data and improve suggestions and recommendations while making them more strict for doctors. After receiving feedback from multiple doctors and field testing, we completely reworked the front end.
