Sergii K. Embedded Systems, Firmware and Hardware Prototyping

My name is Sergii K. and I have over 15 years of experience in the tech industry. I specialize in the following technologies: WiFi, Embedded C, Firmware, Microcontroller Programming, C++, etc.. Some of the notable projects I’ve worked on include: Ultra low power wireless capacitive fuel level meter, Hardware and Firmware for the vehicle monitoring terminal, Firmware for the magneto strictive liquid(and LPG) level meter, Firmware for the fuel flow control display unit, Head of R&D & lead programmer for a digital communication system, etc.. I am based in Odessa, Ukraine. I've successfully completed 10 projects while developing at Softaims.

Information integrity and application security are my highest priorities in development. I implement robust validation, encryption, and authorization mechanisms to protect sensitive data and ensure compliance. I am experienced in identifying and mitigating common security vulnerabilities in both new and existing applications.

My work methodology involves rigorous testing—at the unit, integration, and security levels—to guarantee the stability and trustworthiness of the solutions I build. At Softaims, this dedication to security forms the basis for client trust and platform reliability.

I consistently monitor and improve system performance, utilizing metrics to drive optimization efforts. I’m motivated by the challenge of creating ultra-reliable systems that safeguard client assets and user data.
