About

I am a technical and CAD-oriented professional with experience in maintenance, production support, 3D modeling, technical documentation, 3D printing and prototyping.

My background combines practical industrial experience with CAD design and software engineering knowledge. I work with Autodesk Inventor, AutoCAD, Fusion 360, SolidWorks and other engineering tools, and I am interested in supporting engineering teams remotely with CAD modeling, 2D drawings, design preparation, prototype development and manufacturing documentation.

I currently work in a technical maintenance and engineering-support environment within the medical industry, where precision, troubleshooting, documentation and reliability are very important.

I am especially interested in projects related to mechanical design, product development, technical documentation, 3D printing, automation support and design-for-manufacturing.

Experience

CAD Designer / 3D Printing & Prototyping Support Protowave · Self-employed Feb 2024 – Present 2 yrs 5 mos Novi Sad, Vojvodina, Serbia Independent work on CAD modeling, 3D printing, prototyping and technical preparation of parts.

Projects include 3D modeling of mechanical parts, preparation of models for FDM/SLA printing, reverse engineering support, prototype development, technical drawings, small mechanical assemblies and design improvements for manufacturability.

Experience with materials such as PLA, PETG, TPU, ABS and engineering-oriented 3D printing applications.
Maintenace Engineer Mikrotec Optika · Full-time Jan 2024 – Present 2 yrs 6 mos Serbia Working in a technical maintenance and engineering-support environment within the medical manufacturing industry.

Responsibilities include technical troubleshooting, machine maintenance support, coordination of maintenance activities, communication with technicians and external service providers, spare parts tracking, process understanding and documentation support.

This role has strengthened my practical understanding of production systems, technical reliability, problem solving, documentation and industrial workflows.

Other experience

Machine Design and Mechanical Concept Development Designed mechanical concepts for custom machines and automation-related systems. The projects included machine structure development, linear motion concepts, component layout, actuator positioning, mounting brackets, protective covers, and prototype-ready CAD models.

The main focus was on creating practical and manufacturable designs that connect mechanical movement, industrial components, and real production needs.
Digital Inline Refractometer Prototype Designed a concept prototype of a digital refractometer system intended for measuring liquid concentration in an industrial environment. The project included the mechanical concept, sensor positioning, optical layout idea, waterproof housing concept, and preparation for 3D printed prototyping.

The design was focused on creating a compact sensor module that could be placed inside or near a liquid container, with protected electronics and controlled light measurement conditions. The system concept included an LED light source, optical sensing element, prism/glass interface, sealed enclosure, and mounting features for practical use.
Smart Device / Sensor Prototype Concept Worked on concepts for smart devices involving sensors, displays, and custom 3D printed housings. The project combined electronics layout thinking, enclosure design, and practical prototyping.
Industrial Machine Spare Parts and Brackets Project type: Mechanical Design, Industrial Components
Designed simple mechanical replacement parts, brackets, holders, covers, and custom supports for industrial use. Projects required practical understanding of fit, strength, assembly, and manufacturing limitations.

Skills used: Mechanical Design, Autodesk Inventor, AutoCAD, 3D Printing, Technical Drawings
Custom 3D Printed Functional Parts Designed and prepared custom functional parts for FDM 3D printing based on measurements, sketches, and practical requirements. The work included part modeling, dimensional adjustments, material selection, print orientation, tolerances, and preparation for real-world use.
