What clients say

Connected 4 healthcare systems (EasyPractice, Whereby, Vena EHR, Gravity Forms) into one workflow. When a booking happens, patient gets created in EHR, video link generated, screening form sent. After consultation, AI generates clinical notes. Client called me "technically skilled with structured approach."

Healthcare Middleware — Menokind

5.0★ — "Will hire again"

Rebuilt a site from scratch with modern stack. Client said "great experience" and came back for more work. That's the loop I optimize for.

Website Recreation

5.0★ — Repeat client

Reviewed and optimized a landing page. Client feedback: "Positive attitude, excellent communication." Sometimes the best code is knowing what not to change.

5.0★ — "Delivered perfectly"
