HARDWARE PROTOTYPING
Software Engineer specialized in real-time systems, healthcare software and IoT integrations. Experienced in designing and developing scalable monitoring platforms handling high-frequency medical data including ECG, PLETH and vital signals. Strong background in system architecture, performance optimization and distributed device management.
Delivered production-grade systems currently in active use across multiple hospitals in Turkey. Combines deep software engineering expertise with hands-on hardware and embedded systems knowledge to deliver resilient, end-to-end solutions. Over 4 years of professional experience across healthcare technology and international multi-partner projects.
Case Studies & Production Code
Independently architected and developed a configurable real-time ICU monitoring system. Features ECG, PLETH and invasive Blood Pressure waveform visualization via SignalR, alarm mechanisms, dynamic grid layout and full admin-controlled UI customization. Database schema, architecture and all technology selections made solely by the engineer.
Multi-hospital real-time monitoring hub providing VPN-free simultaneous connectivity to all hospital sites. Features live patient vital data aggregation, server resource monitoring (CPU/RAM), device health tracking with automated alerts, Turkey map-based hospital status visualization (green/red/grey), web-based RDP access and remote device command execution.
Hospital-wide ICU central monitoring platform aggregating real-time data streams from multiple bedside devices simultaneously. Features room-based patient assignment, live vital sign feeds, alarm management across wards and role-based access control for clinical staff.
Hospital-grade real-time fetal monitoring platform built from scratch. Includes waveform rendering for fetal heart rate and uterine contractions, multi-pregnancy support, annotation tools, pause/resume control, vital sign entry and dynamic PDF reporting with clinical data overlay — reducing manual documentation time by over 80%.
Scalable multi-patient central monitoring platform aggregating real-time CTG waveforms from multiple gynecology devices simultaneously. Resolved critical memory leak and eliminated 100% CPU utilization caused by an unoptimized waveform rendering pipeline.
Led end-to-end software development of an AI, IoT and 5G-powered international healthcare platform across a 13-partner consortium (Turkey, UK, Spain). Implemented SSO authentication system and delivered API documentation enabling partner-side integrations. Includes doctor-patient appointment system and AI-assisted diagnostics.
Intensive care hospital module system including structured doctor forms, multi-table audit logging and cross-database reporting architecture. Built for clinical workflow management in ICU environments with full traceability of medical decisions.
Designed and deployed OTA firmware update infrastructure for 45+ ESP32 devices across hospital sites. Features an embedded web server for remote firmware upload, SSID/password management, remote restart and a real-time telemetry dashboard — eliminating physical access for field device updates.
Custom over-the-air firmware update framework for ESP32 and Arduino-compatible boards. Features a drag-and-drop web UI for binary upload, rollback support, version tracking and secure HTTPS delivery.
Ground-up designed and assembled FDM 3D printer with custom Marlin firmware configuration, precision-tuned motion system, auto bed leveling and dual-zone heated chamber. Achieves 0.1 mm layer resolution and is actively used for production.
Custom-built structured-light 3D scanner with a rotating platform, laser line projector and camera. Captures point-cloud data processed into printable STL meshes for reverse engineering physical objects.
3D-printed bionic arm controlled via a flex sensor glove with real-time motion replication. Each finger maps to a servo motor via Arduino, faithfully replicating the wearer's grip and gestures. Designed as a low-cost prosthetic research prototype.
