Embedded Systems | Firmware | PCB Design | Mechanical Design I help clients develop reliable prototypes and products in embedded systems, electronics, PCB design, and mechanical design. I have 3+ years of experience in the development of military/defense equipment, including UGVs, RCWs, and rocket subsystems, as well as prototyping medical, industrial, and musical equipment. Core skills: - Firmware development for MCUs (C/C++) on ARM platforms, STM32, ESP32, and Arduino; - Automation development on embedded systems and industrial equipment. - Industrial communications protocols knowledge (CANopen, Ethernet, EtherCAT, Serial and other) - PCB and circuit design; sensor integration; automation; - 3D/2D modeling and drafting; Fusion 360; AutoCAD; - MATLAB/Simulink; LabVIEW; C#; - 3D printing and prototyping. Available equipment: multiple ESP32, STM32, and Arduino platforms for prototyping, Ender 3 S1 Pro and Bambu Lab P1S 3D printers, and a Rigol DHO924S oscilloscope for testing and verification. I also have access to quick PCB and CNC production. Responsive, reliable, and focused on practical, on-time results.

I have 20+ years of experience in various branches of Electrical Engineering: Power Electronics (thyristor controlled battery chargers and inverters), Microcontroller and PLC programming (Intel 8051 , Siemens SAB 80515 and SIMATIC S5 PLCs), Railways electronics maintenance and development, Marine, PV solar systems evaluation and design, Automation, Earth fault Monitoring relays for LV AC networks and el. motors. I am focused now on the Electronic Circuit Design, PCB Design (Dip Trace), SCR controlled battery chargers, Prototype Manufacturing, Arduino and ESP32 based Hardware Development and Programming..

Fixing, unlocking and modernizing legacy Excel & Word VBA solutions, including fillable PDF forms with JavaScript solutions. I help businesses fix, unlock, automate and modernize MS Office solutions that are critical to their daily operations. My focus is not just creating new macros, but rescuing broken, slow, or locked files, improving reliability, and delivering tools that non-technical users can safely rely on. If your file is not working the way it should, send me a message and I’ll take a look. I’m happy to review your file and suggest the best solution. 1) MS Excel (VBA, Templates & XML): ✓ Fixing and debugging existing VBA macros ✓ Optimizing slow or unstable Excel files ✓ Unlocking protected workbooks, sheets, and VBA projects (for legitimate owners) ✓ Building robust automation tools with UserForms ✓ Automating reports, calculations, and data processing ✓ Organize messy data ✓ Improving structure, validation, and error handling ✓ Legacy Excel file recovery and modernization ✓ Data cleaning (remove duplicates, fix formatting, validate entries, organize imported data) ✓ Fixing errors #DIV/0, #N/A, #REF, #VALUE 2) MS Word (VBA, Templates & XML): ✓ Creating and fixing advanced Word templates ✓ Automating document generation from Excel or databases ✓ Working with XML data binding and Content controls ✓ Building robust automation tools with UserForms ✓ Repairing corrupted or poorly structured Word files ✓ Standardized styles, layouts, and document logic ✓ Protecting templates while keeping them user-friendly ✓ Unlocking protected files, and VBA projects (for legitimate owners) 3) Fillable PDF forms (Creation, Recovery & JavaScript Fixes): ✓ Converting Word templates into professional, fillable PDF forms ✓ Repairing and improving existing fillable PDF forms ✓ Unlocking secured or restricted PDF documents (for legitimate owners) ✓ Fixing broken or unreliable PDF JavaScript code ✓ Creating and correcting form logic (calculations, validations, dependencies) ✓ Adding and optimizing text fields, checkboxes, dropdowns, and radio buttons ✓ Implementing digital signature and date fields ✓ Ensuring cross-device and cross-PDF-reader compatibility ✓ Cleaning up poorly structured or unstable form fields without breaking layout

I help companies organize CNC machining and welded steel production in Eastern Europe. Instead of managing multiple suppliers, languages, and quality risks, you work with one technical point of contact. I coordinate: • CNC machining (milling & turning) • Laser cutting & bending • Welded steel assemblies • Small batch production • Prototyping • Quality control You receive finished parts with predictable costs and realistic lead times. In addition, I provide CAD modeling and technical drawing support for clients who need engineering preparation before production. This allows you to move from concept to finished part through one structured process. Ideal clients: • Hardware startups • Machinery manufacturers • Industrial designers • Construction-related companies • EU companies seeking reliable nearshore production I focus on technical, small-to-medium production runs. Mass production is outside my scope.

I am Ivan Benedetić, Mr.Sc. Civil Engineer from Belgrade, Serbia, with 37 years of international experience in civil engineering, project management, and design. I have successfully worked on residential and commercial high-rise buildings, oil and gas facilities, infrastructure, and hydro-technical projects across Serbia, Russia, Libya, Ghana, and Equatorial Guinea. My key expertise includes: • Project management and site supervision • Civil and structural design • Cost estimation and bills of quantities (BOQ) • Project planning and scheduling (MS Project) • Technical documentation and reporting • English ↔ Russian ↔ Serbian/Croatian translation of engineering materials I am computer-literate and regularly use AutoCAD, MS Project, Excel, and Word in my work. Clients value my precision, responsibility, and deep practical experience gained through nearly four decades of hands-on engineering in diverse environments. I can deliver project planning, estimating, and technical translation tasks quickly and professionally from my home office. Let’s discuss how I can help make your project more efficient and cost-effective.
