Define the field before anyone fills it
Data dictionaries, permissible values, mandatory fields and duplicate prevention, agreed with investigators before the first record exists.
AIIMS New Delhi · Obstetrics & Gynaecology
I run electronic data capture for clinical and public-health research at AIIMS New Delhi. I define the fields, write the rules that guard them, close the queries they raise, and hand over a dataset an analyst can rely on.
Research data has a lifecycle, and it only holds if every stage does. These four are mine on every study.
Data dictionaries, permissible values, mandatory fields and duplicate prevention, agreed with investigators before the first record exists.
Real-time entry validation, range and consistency checks, completeness review and project trackers that show what is still missing.
Data-quality issues raised with investigators, tracked, and followed through to resolution rather than logged and left open.
Version-controlled study files, training records, change logs and audit trails, so a clean dataset can be locked and defended.
Built for the Department of Obstetrics & Gynaecology. On both I was the bridge between investigators and the technical team: requirements, data definitions, validation rules and acceptance testing. Both demos open in the browser.
One role-based record of projects, project staff, location-based attendance, meetings and minutes, documents and assets across several AIIMS sites — with one agreed definition of every field.

A patient, clinician and administrator application for pregnant women with a diabetic history: glucometer readings with range checks, missed entries surfaced to the clinician, and the audit, export and backup a research dataset needs.

Clinical research coordination and data management since 2020, on a computer-science and IT background.

Happy to walk through either system, the data dictionaries behind them, or how a query gets from raised to closed.
