Hi, I'm Sameer Soni
Senior Systems &
I write systems software, care about correctness, and have the scars to prove it. Over 10+ years of engineering experience across industrial, medical, and IoT domains, specializing in embedded Linux, kernel drivers, and high-availability distributed platforms.
About & Core Principles
Deep Systems Focus
I thrive at the boundary of hardware and software. Developing device drivers, handling complex interrupts, and tailoring custom Linux distributions (Buildroot) are my natural playgrounds.
Obsessive Correctness
In industrial control systems, medical diagnostics, and automotive networks, failures are not options. I bring rigorous static analysis, unit-testing, and strict threat modeling (OWASP) to every pipeline.
Constrained Architecture
Designing secure OTA update systems and modular OS upgrade paths for legacy, low-memory IoT nodes. Extracting peak performance from tight CPU budgets and limited RAM.
Professional Milestones
Software Engineer
Frankfurt am Main, Germany
- Designed and implemented a custom PoE++ (IEEE 802.3bt) driver for the Microchip PD692x0, supporting up to 90W per port and enabling scalable power management for industrial Ethernet switch platforms.
- Engineered a Layer 3 routing stack, enabling static, inter-VLAN, and dynamic control-plane routing integrated with the BIRD Internet Routing Daemon and accelerated by hardware TCAM forwarding.
- Implemented dynamic route lifecycle management using custom exponential backoff algorithms for retry and network convergence control, significantly increasing switch routing stability.
- Developed a custom WS2812B LED driver over SPI, encoding exact microsecond timing requirements into SPI waveforms to ensure robust control across chained hardware LEDs.
- Created FPGA-based LED driver logic, delivering deterministic timing and high-efficiency parallel LED status control in harsh industrial environments.
- Collaborated within agile teams to diagnose and optimize embedded web application issues, resolving critical customer-reported bugs.
Werkstudent (Working Student)
Frankfurt am Main, Germany
- Spearheaded systematic field-testing of next-gen smart eBikes, gathering 150+ hours of structured performance data across 10+ real-time telemetry parameters.
- Designed and engineered a centralized overview monitoring dashboard to consolidate multi-run data, enabling rapid trend analysis and early-stage defect pattern identification.
- Authored and executed highly structured automation test suites for Android and iOS companion apps using Robot Framework and Python, uncovering and logging over 100+ critical functional/integration defects.
- Automated manual test-run data parsing and reporting scripts, increasing data pipeline speed and reducing human reporting effort across test iterations.
- Supported warehouse and inventory coordination workflows to ensure reliable prototype tracking and logistics management.
Advance Software Engineer
Bangalore, India
- Architected and built an end-to-end secure Over-The-Air (OTA) firmware update and remote debug log retrieval system from scratch for legacy Linux-based, extremely resource-constrained IoT gateways.
- Designed and implemented a successful OS upgrade pathway, safely flashing legacy nodes while avoiding expensive on-site visits and hardware replacement costs.
- Engineered a secure TLS 1.3 communication layer, incorporating complete PKI certificate generation, provisioning, and automatic local lifecycle rotation.
- Integrated SonarQube static code analysis checks natively into the CI/CD pipeline, lowering high-severity code smells and potential security hotspots by 90%.
- Led structured threat modeling sessions using OWASP Threat Dragon, formulating zone/conduit diagrams and detailed CVE analyses to guide safe architectural choices.
- Directed a Six Sigma DFSS process optimization project, cutting pipeline overheads to secure a 30% speed boost (awarded the Honeywell Bravo Award).
Senior Engineer - Design & Development
Bangalore, India & Germany
- Developed business-critical configurations and features for the Procedure Manager, a C# DLL-based engine managing real-time clinical workflows for Siemens Artis X-ray and Angiography setups.
- Maintained high engineering benchmarks by implementing SOLID design principles, single-responsibility designs, and rigorous peer-reviews.
- Engineered a WebSocket-based messaging component and published a set of clean integration APIs, making the systems manager a high-efficiency clinical communication hub.
- Coordinated directly with clinical experts, including shadowing live surgical environments, to understand deep safety boundaries and failure-tolerance constraints.
- Traveled on-site to Germany to conduct complex hardware-software systems integration, working hands-on with cross-regional engineering and electrical hardware teams.
Software Engineer
Bangalore, India
- Created features for HotScan, a high-throughput distributed transaction filter used by global banking networks to scan international transfers for embargo lists.
- Designed and deployed a highly performant, rule-based screening engine that reduced manual filter reviews by 40% while ensuring zero regulatory false negatives.
- Joined as a graduate hire and quickly grew to independently deliver complex core modules within CGI's high-stakes distributed architecture.
