EMBEDDED SYSTEMS & IoT
ROBOTICS AUTOMATION
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.
Full-featured back-office system for an international jewelry e-commerce platform. Includes product catalog management, multi-currency pricing, order lifecycle tracking, scheduled background tasks via Hangfire, Azure Blob storage integration and granular role permissions.
International e-commerce platform serving the jewelry industry with full product catalog, multi-currency pricing, order lifecycle tracking and Azure Blob storage integration for media management. Built with ASP.NET MVC and .NET Core supporting high-volume transaction workflows.
Centralized real-time monitoring and control platform for ICU medical devices. Windows desktop application managing hospital medical devices over serial and network connections with real-time device status, configuration management and event logging.
Full-stack café management application with QR code-based table ordering, menu management, real-time order tracking for staff, bill generation and admin reporting dashboard.
Comprehensive dormitory management system covering student registration, room assignment, entry/exit tracking, fee management and staff communication. Built with layered architecture and role-based access.
End-to-end hospital information management system covering patient registration, appointment scheduling, doctor assignments, prescription management and billing. Implements stored procedures and T-SQL functions for optimised reporting.
Point-of-sale and inventory management application for a patisserie business. Handles product catalogue, daily sales tracking, stock level alerts, order management and revenue reporting.
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.
Voice recognition and password-controlled access system with logging and alert mechanisms. Features an infrared laser tripwire grid, servo-locked door mechanism and audible alarm. Automated alerts triggered on unauthorized access attempts.
Remotely controlled amphibious hovercraft operating on both land and water. Dual thrust fans for lift and propulsion, custom foam and carbon-fibre hull, ESC-driven brushless motors and an Arduino-based mixing controller.
DIY vertical-axis wind turbine with hand-wound alternator coils and a custom 3D-printed rotor. Integrated Arduino charge controller regulates output to a LiFePO4 battery bank.
Real-time speech-to-text display system. Captures audio via a microphone module, converts spoken words to text using an embedded recognition module and displays output on a 16×2 LCD screen.
Sensor-based barrier automation with custom hardware and software. Ultrasonic sensors detect vehicle presence in bays, servo-actuated entry/exit barriers and an LCD counter display available spaces.
Autonomous robot navigating along a defined path using an array of IR line sensors. PID-controlled motor driver ensures smooth cornering and speed adaptation. Competed in inter-university robotics competitions.
Autonomous mobile robot with ultrasonic obstacle detection and a 3-DOF robotic arm for pick-and-place operations. Combines path-planning algorithms with servo-based arm control.
Custom digital counter circuit using 7-segment displays driven by BCD decade counter ICs. Counts up to a user-defined preset value with reset functionality, implemented purely in hardware without a microcontroller.
