Embedded & Real-Time DSP Development
Deep expertise in designing and implementing real-time digital signal processing systems, including wireless communication standards (3GPP: LTE, 5G/NR), audio processing, physical modeling, and floating to fixed point conversion. Programming in C and C++ (up to C++17) for embedded and DSP targets such as TI C66x and Tensilica DSP cores.
5G/NR and LTE Physical Layer Engineering
Extensive hands-on experience with 5G-NR and LTE L1/L2/L3 software design and architecture, including UE modem firmware development, OpenRAN CU/DU functions, PUCCH/PUSCH implementation, noise canceling, noise power estimation, and Digital Front End I/Q imbalance compensation.
AI & Python Prototyping
Practical experience developing AI agents for e-Commerce using Python, ollama, FASTapi, and Langchain. Prototyping and testing with Python and Matlab, including AI workflow design and integration of large language models and autonomous agents.
Matlab/Simulink/Simscape Modeling
Proficiency in Matlab, Simulink, and Simscape for signal processing, reference model design, and physical system simulation, including development of an Electric Vehicle Simulator with focus on electric powertrain.
Applied Mathematics & Algorithm Design
Strong background in applied mathematics including linear algebra, estimation theory, system theory, and optimization, applied to algorithm specification, design, and optimization in DSP and communication systems.
MCU/Bare Metal & ARM Programming
Experience with MCU and bare metal programming on ARM architectures, including Linux development and basic system administration.
Agile Project Management & Team Leadership
Experience as Scrum Master and feature lead, including release planning, backlog maintenance, prioritization, team mentoring and coaching, and coordinating scrum teams across multiple sites with 150+ engineers per release.
DVB & Conditional Access Systems
Experience in Conditional Access component integration, certification of CA systems in DVB devices, and design, implementation, and testing of drivers for DVB STBs.
GitLab & Development Tooling
Familiarity with GitLab for version control and CI/CD workflows, as well as tools such as Jira and MS-Office including basic Project management.
