I build healthcare software - and fix it. HIPAA-compliant EMR/EHR systems, telehealth, patient portals, healthcare AI. Vibe-coded app and now it touches real patient data? I find what's broken before someone else does. If you're a therapist, physician, or practice owner with an idea for a platform - I've helped dozens of founders just like you turn your idea into working software. I work with practices, health startups, and digital health companies across the US, Canada, Europe, and APAC. ✅ 12+ years in software development (Healthcare focused) 🎯 100% Job Success Score 🏅 Top Rated Developer How can I help you? 🛡 Built fast and not sure it's production-ready? I review & fix existing healthcare apps - security audit, HIPAA/PHI handling, access control, audit trails, performance. Fixed-price audit first: you get a prioritized findings report of what's leaking, what's fine, and what to fix first. Then I fix it, or your team does with the report. Ideal before a customer security review, investor due diligence, or going live with patient data. 👨‍💼Need a patient-facing platform? I'll build your portal with secure messaging, lab results access, medication reminders, appointment self-scheduling, digital check-in, patient onboarding, consent management, and health dashboards for web, iOS, and Android. Your patients get a better experience, you get fewer phone calls. 🧑‍⚕️Building for clinicians? I deliver EMR/EHR systems with clinical charting, SOAP notes, progress notes, treatment plans, care plans, care coordination, and discharge summaries, as well as practice management software (PMS) for multi-location clinics covering scheduling, billing, and clinic operations. 📱Launching telehealth?

Hello, my name is Sergey. I'm high-performing software engineer / engineering leader with 25+ years of experience with proven track record. Last 15 years I've been working for world-class companies and projects with 20M+ audience. What I'm good at: • Building stuff, getting things done • Time / quality / cost balance • Technical leadership. I build engineering teams and support friendly, productive and collaborative environment. • Software / Data / Solution architecture at scale. I designed and implemented a lot of stuff benefiting companies for years and making me proud. • Software development. Even while playing manager or architect role, I don't give up coding to "keep my hands dirty". • Reliability engineering. I love to solve reliability problems at scale (huge traffic, low latency, fault-tolerance, performance stability, zero maintenance downtime, etc.). • Both team play and individual contribution. I have experience of both working for large public companies with thousands of engineers and building backend from scratch on my own for several startups. I have ASM/C/C++ background. I don't use them quite a while, but it still helps me to understand many things better. I pick up languages / frameworks quite quickly. At the moment, I mostly use Java technologies. I have a strong knowledge and experience in the following domains: • Trust and safety • Marketplaces • Social networks (I managed a backend team for social network with 30M+ audience) • Traditional hosting (lower level for clouds) • Billing and payment systems If you're looking for remote principal / staff / senior engineer / lead / manager - please drop me a message.
