🚀 Who I Am
I am Sanjoy Roy, a Senior Cloud Backend Engineer, Healthcare Technology Consultant, and independent researcher with over 15 years of international experience. I specialize in building scalable, secure, and cloud-native backend systems, focusing on healthcare informatics and digital health transformation. My work bridges software engineering, cloud infrastructure, and patient-centered health IT innovation. Currently, I am pursuing research on designing interoperable EHR systems for multi-institutional and rural healthcare networks. Passionate about technology, health equity, and lifelong learning, I aim to create sustainable solutions for a healthier world.
🛠️ What I Do
I offer end-to-end solutions across three key areas:
-
Cloud Backend Architecture & Full-Stack Application Development
I design secure, modular backend systems with .NET, Python, and microservices—complemented by responsive frontends built with React and Blazor. I deliver everything from greenfield SaaS platforms to legacy modernization projects, backed by clean architecture and cloud-native principles. -
Cloud Infrastructure & DevOps Automation
I build and manage cloud environments using AWS, Azure, and GCP. My work includes Infrastructure as Code (Terraform, Bicep), CI/CD pipelines (GitHub Actions, Jenkins), container orchestration (Docker, Kubernetes), and robust monitoring with Prometheus and Grafana. -
Healthcare IT Architecture & Compliance Consulting
I lead healthcare digital transformation initiatives—from EHR/HIS deployment to interoperability using HL7, DICOM, LOINC, SNOMED CT, and RxNorm. I help organizations ensure HIPAA/GDPR compliance, automate labs, integrate AI/IoT devices, and prepare SOPs that align with operational standards.

Academic Engagement
Alongside professional software development and healthcare IT consulting, I am currently pursuing independent research focused on designing interoperable, patient-centered cloud-based EHR systems for rural and multi-institutional healthcare networks. Additionally, I am drafting an educational book, “Python Start Here,” aimed at supporting new programmers. This academic journey complements my passion for building sustainable, human-centered digital health solutions.
