Hello! I am an electrical engineer with over 5 years of experience in embedded systems and control engineering. If you need guidance on the best way to frame your electronics project, someone to do your embedded software (firmware) coding, or if you need help tuning a controller, I'd be happy to work with you. My experience: • Embedded software and hardware architecture • Control system design and implementation • Firmware development in C/C++, bare or RTOS • Python scripting • IoT protocols: LTE, MQTT, TCP/IP, HTTP, CoAP, BLE, GNSS • Communication protocols CAN, SPI, UART, I2C • Various boards and MCUs: STM32, TI, AVR, nRF, ESP, Arduino, RPi

Hi, I’m Aleksandar – an embedded hardware engineer who helps companies turn ideas into real, reliable PCBs and embedded systems for motor control, IoT, robotics, audio and consumer products. For the past 10+ years I’ve been designing electronics that actually ship: from early block diagrams and first schematics, through PCB layout and firmware, all the way to tested prototypes and manufacturing files. I like owning the whole hardware + firmware stack so there are no gaps between disciplines. I don’t see this as a “one-off gig” type of work. I try to work as part of your team: asking the right questions, pushing back when something is risky, and making sure what we design is something you can build, test and maintain. What I do • Motor drivers for brushed and BLDC motors in high-precision actuators and motion systems • Embedded and single-board computer hardware + firmware (STM32, ESP32, SAM E5x/SAMD, etc.) • IoT devices with a focus on low power consumption and long battery life • Consumer electronics and small product PCBs (wearables, controllers, audio and wireless devices) • Communication and interface design: RS-232, RS-485, CAN, Ethernet and industrial buses • Bootloaders and firmware update solutions for different MCUs and transports • System design for multi-axis robotic systems: electronics, PCB and cabling • Manufacturing preparation: BOM cleanup, DFM, and coordination with vendors/CMs Tech stack • MCUs: STM32, SAM E5x/SAMD, ESP32, 8-bit MCUs • Tools: Altium Designer, KiCad, Fusion 360 • Firmware: C / Embedded C, RTOS How I work • Clear, staged milestones: requirements → schematic → PCB layout → prototype → bring-up → test report • Regular updates with screenshots, logs and measurements, so you always know where things stand • Careful documentation so another engineer can open the files months later and understand the design I work efficiently and aim to reduce total project cost by avoiding redesigns and dead ends. If you need someone who can take responsibility for both the electronics and the embedded side – and deliver something your team can build on – I’d be happy to talk.

Technology projects rarely fail because of technology. They fail because priorities aren’t aligned, communication breaks down, risks aren’t managed early enough, or teams aren’t working toward the same goal. That’s where I come in. For the past 17+ years I’ve been helping technology companies build stronger delivery organizations, improve operations, lead cross-functional programs, and solve complex execution challenges. I’ve managed global teams across Europe, the UK, India, and North America, worked with Fortune 500 customers, and partnered closely with Product, Engineering, Customer Success, Professional Services, and executive leadership. Most of my work sits where technology meets business. Whether it’s leading a large implementation, improving delivery processes, building governance frameworks, scaling support and cloud operations, or helping teams adopt AI into their daily workflows, my focus is always the same: make execution simpler, more predictable, and easier to scale. I enjoy stepping into situations where there are too many moving parts, unclear ownership, or growing operational complexity. Bringing structure, aligning stakeholders, and helping teams deliver successfully is what I’ve spent my career doing. I can help with: • Technical Program & Project Management • PMO setup and delivery governance • Cross-functional program leadership • IT Operations & Cloud Operations • Service Delivery Management • Executive reporting & stakeholder management • Process improvement & operational excellence • AI workflow adoption and automation • Customer onboarding & implementation programs • Team leadership, coaching, and organizational scaling If you’re looking for someone who can keep projects moving, bring clarity to complex initiatives, and work comfortably with both engineers and executives, I’d be happy to discuss your project.
