A HIPAA violation costs a healthcare business its reputation, not just a fine. I build HIPAA-compliant patient portals, digital intake, and clinical documentation platforms that pass compliance review the first time — not after a scramble. 🏥 ⚡ We may be a great fit if: ⤷ You're a healthcare operator (in-home care, clinic, telehealth, mobile health) juggling booking, intake, and documentation across disconnected tools ⤷ You need EHR/EMR-adjacent architecture and healthcare interoperability built by someone who understands real clinical workflows, not just "add a login screen" ⤷ You want a long-term product partner across strategy, UX, and engineering — not a one-off freelancer 🌟 What I build: ⤷ HIPAA-compliant patient portals — booking & digital intake platforms ⤷ Field-staff mobile apps — visit management, clinical documentation, patient charts ⤷ Healthcare software development with HIPAA-compliant architecture — role-based access, encrypted communication, complete audit logging ⤷ Healthcare interoperability — data structures built to work cleanly with HL7/FHIR-based EHR/EMR systems ⤷ Bilingual/accessible patient experiences for underserved markets ⤷ End-to-end product strategy through engineering delivery ✅ Recent work: For AllmedsNow in-home care team: their nurses were relying on scattered tools to know where to go, what to do, and how to document it. I built NowApp — one mobile app where a nurse gets their visit, sees the physician-approved order and full patient chart, delivers care, and documents everything with a timestamped, audit-ready trail — so the agency can pass a compliance review with confidence instead of piecing together records after the fact. Delivered in 14 weeks. For the same company's operations team: running visits, nurses, and patient records across scattered tools meant no single source of truth for the business. I built the admin panel — one place for the team to assign nurses, track every visit's status, manage patient and clinical records, and keep operations visible end-to-end, instead of chasing updates across separate systems. For the same company's patient side: launching in-home IV therapy in Florida with no booking system meant lost patients and manual intake. I led product strategy and built MDHealthNow — a HIPAA-compliant patient portal where a patient can find a treatment, book it, pay, and complete medical intake before a nurse ever shows up, cutting the admin work down to what a physician actually needs to review. I also caught something competitors missed: a large Spanish-speaking market with no one serving it well, so we shipped bilingual support as a core feature, not an afterthought — opening a market segment the client wasn't otherwise going to reach. Delivered in 4 weeks. Now live as the company's first digital product. Client feedback: "Tanzeel is excellent at his work. His deep knowledge of the healthcare domain, especially regarding HIPAA compliance in healthcare software, has been extremely valuable for our projects... he has become a trusted strategic partner for our company." Together, these three pieces run one connected pipeline: a patient books → completes intake → gets matched and dispatched by admin → the nurse documents the visit in the field → the agency has a defensible, end-to-end record of everything. Most vendors in this space sell you one piece of that. This was built as one system. 🔢 My stats: 100% Job Success | Top Rated Plus $30K+ earned, 12 completed projects 🔧 My Tech Stack ⤷ Next.js/React, React Native/Flutter — patient portals & cross-platform field/nurse apps ⤷ Node.js — secure APIs connecting it all ⤷ AWS — HIPAA-eligible hosting & infrastructure ✗ Not a great fit if: ⤷ You want the cheapest possible build with no defined scope ⤷ You're looking for someone to bolt on "HIPAA compliance" after the fact rather than build it in from day one ⭐ Tell me what you're building — I'll tell you honestly whether it's a fit. ● Available for immediate collaboration & long-term partnerships.
