Work Experience
Senior Mobile (Bluetooth) Application Developer
Toyota Material Handling, Inc - Main
- Focused on the support of connectivity options for devices: BR/BER, BLE, and x802.11 integration across the stack.
- Contributed to the robustness of the Bluetooth peripheral implementation, including research of the Gobbledegook library and its usage to remedy long-standing bugs.
- Optimized firmware performance/memory footprint based on analysis made with the help of the modern tracing technologies of Linux kernel (perf, eBPF).
- Contributed to the architectural design and reviews of several low-level components related to networking and Bluetooth.
- Enhanced developer tooling; made a container environment that's portable and could speed up project setup for newcomers.
Senior R&D Engineer
Monk
- Created an overlay network for containers managed by an in-house developed orchestrator with WireGuard technology.
- Conducted various container runtime engines and interfaces. Implemented transition of orchestrator container runtime from Docker to Podman.
- Debugged hard-to-find bugs in a big codebase and made gradual iterative improvements.
C and Python Software Engineer
Dressler Consulting
- Added features and visualization options for the custom system profiler, per-process network, disk IO, etc., for hardware running stripped-down Linux, written in C.
- Developed parts of the custom BSP based on TI SDK for the hardware box (ARMv7).
- Automated and enhanced version control tools based on Git to streamline the development process, resulting in faster development and deployment times.
- Cross-compiled the NGINX web server and tweaked it for the particular needs of the ARMv7 based Linux box.
- Added functionalities to the configuration web server written in Python.
- Audited security policies on the operating system level, including permissions, ownerships, setuid, and sudoers.
- Worked on enablement of LTE and Wi-fi for infotainment system based on AGL's UCB. Researched and made heavy use of the Yocto project's infra and tooling.
- Made security audit of UCB-based firmware image and hardened boot process.
Embedded Software Engineer
Sirin Software
- Maintained and enhanced the build system for a router with custom Debian-based firmware with Bash and Python scripts.
- Developed networking scripts using iproute2 tools for device startup, connection health monitoring, and accommodating new networking rules "online."
- Patched parts of the U-Boot bootloader and configured kernel features.
- Worked on the OTA (over the air) firmware upgrade feature two-partitioned setting, modeled as a state machine with coordinated steps in the bootloader, kernel, and userspace.
- Handled the POC implementation of the LoraWAN network server in C language. Refer to Lora-alliance.org/about-lorawan.
- Added fixes and custom changes to Cavium SDK (Makefiles, Bash).
- Planned and led frequent code reviews in an agile manner.
Embedded Software Engineer
Anyware Services
- Developed an indexing solution for a database of telephone numbers using a trie data structure.
- Created a custom instrumentation solution that fit the project's particular needs, running software on a different node in distributed computation manner.
- Provided input to the lead architect during the architecture devising phase of the project.
Teaching Assistant
Free University of Tbilisi
- Helped students with their homework assignments, questions, and queries.
- Graded student's work according to strict guidelines, taking into account objective measures such as test passing, code quality, and an estimated amount of effort being put by the student.
- Graded mid-terms and final examination submissions under the supervision of lecturers.
