Last position:
Embedded Systems Consultant / Architect | Integration and Validation Engineer / Manager at Ingenieurbüro Baig
Led the hardware development and validation of a safety-critical 400 V battery management system (BMS) for the TOGG SUV program; performed system architecture reviews, schematic validations, EMC and reliability tests, and root cause analyses in line with relevant automotive standards (ECE-R10, CISPR25, ISO-26262). Coordinated cross-border EU engineering teams, customer reviews, and technical documentation to deliver a production-ready, validated system.
Architected and integrated 22 state-of-the-art ADAS validation vehicles for BMW ADCAM and LIDAR programs at Magna Electronics; synchronized up to 26 heterogeneous sensors (LIDAR, RADAR, cameras, GNSS/INS) using PTP-based timing architectures. Defined the system architecture, HW/SW interfaces for hardware-in-the-loop (HIL) reprocessing, sensor integration strategies, and data acquisition frameworks. This enabled scalable vehicle-level validation, improved validation efficiency by 25%, and reduced project costs by €1.45 million.

Developed automated open-loop hardware-in-the-loop (HIL) environments to accurately test target tracking KPIs, field of view limits, and thermal and voltage-related ECU state machines. Used a highly complex toolchain consisting of CANoe, Lauterbach Trace32, RADAR target simulators, and EMC shielding chambers for RF and system validation. Synchronized global, interdisciplinary teams to speed up troubleshooting and close critical technical gaps.
Reconstructed and validated the product architecture of an electromechanical e-bike by integrating and troubleshooting critical subsystems (BMS, motor control, sensors, HMI, electronic locking systems). Built a comprehensive system-level test bench for functional testing, fault reproduction, and performance analysis; coordinated suppliers and implemented corrective actions to improve reliability and traceability.
Defined the system architecture and validation strategy for a LIDAR platform developed in cooperation with Elmos Semiconductor; evaluated optical measurement concepts, SPAD detector integration, and system requirements, and created technical recommendations for product development and verification.
Developed LabVIEW-based automation and verification software for a high-precision hydraulic and electromechanical test system for FTE Automotive; integrated NI DAQ hardware for high-frequency real-time capture of physical measurement data. Developed automated test sequences, programmable endurance tests, troubleshooting routines, data logging, and analysis tools to improve test efficiency and traceability.
Successfully managed complete engineering life cycles for well-known industrial customers (Magna, Continental, Farasis, FTE Automotive, BMW, Daimler, TOGG) – from requirements engineering and proof of concept through system integration and validation to technical documentation, supplier coordination, and user training.

About the technology
What Rails is
Ruby on Rails is a web framework for building product-focused applications with Ruby. It fits teams that want clear conventions, fast delivery, and a maintainable codebase. Companies use it for customer portals, internal tools, marketplaces, and API-driven products.
What it ships
- Web applications with login, payments, and workflows
- REST and JSON APIs for web and mobile clients
- Admin dashboards and back-office tools
- Background jobs, email flows, and scheduled tasks
- Integrations with external services and data stores
The stack around it
Strong Rails work usually includes Ruby, Active Record, PostgreSQL, Redis, Sidekiq, Hotwire, and RSpec. Experts also know how to shape views, services, and jobs so the app stays readable as it grows. They make sensible choices about gems, caching, and deployment.
When to bring in help
Companies bring in freelance Rails experts when a codebase needs rescue, a feature set needs to move faster, or a product team needs hands-on delivery support. This is common in Germany for SaaS products, e-commerce, logistics, and B2B platforms. Remote work is common, but on-site sessions can help during discovery, refactoring, or handover.
What good specialists do
A strong Rails specialist writes simple, testable code and understands how the framework wants to be used. They spot where convention helps and where a project needs a clearer structure. They also work well with product owners, designers, and other specialists who touch the same delivery flow.
Signs you need Rails expertise
- The app is slow or hard to change
- Tests are thin and releases feel risky
- Background jobs or integrations fail often
- The team needs help with upgrades or refactoring
- A new Rails project needs a clean start
Frequently asked questions
Questions about Ruby on Rails? Start with the answers below.
Ruby on Rails is used to build web applications that need clear business logic and steady delivery. Common examples include SaaS products, customer portals, internal tools, marketplaces, and API backends. It is a strong fit when the team values convention and maintainability.
Rails is often chosen when teams want a highly opinionated framework that speeds up common web tasks. Compared with Django or Laravel, it offers a very Ruby-centric way of structuring code; compared with Node.js frameworks, it usually feels more convention-driven. The right choice depends on your stack, team skills, and long-term maintenance needs.
A strong Ruby on Rails specialist usually brings Ruby, PostgreSQL, SQL, test writing, and background job experience. Knowledge of Hotwire, Stimulus, Redis, Sidekiq, and modern API design is often valuable too. For real products, clean debugging and sensible code structure matter just as much as feature delivery.
A small feature update may need only focused Rails expertise, while a legacy app, upgrade, or architecture cleanup needs deeper experience. The more integrations, background jobs, and business rules you have, the more important it becomes to work with someone who has seen similar systems before. Mature products benefit from specialists who can improve code without breaking flow.
Yes, Ruby on Rails work is often well suited to remote collaboration because most tasks live in the codebase, tickets, and review process. In Germany, many teams work with remote specialists for implementation and debugging, then use on-site time for planning, workshops, or handover. Clear written communication is especially helpful.
Ask which kind of Rails applications they have shipped, how they test their code, and how they handle upgrades and dependencies. Also ask about database work, background jobs, and API design if those are central to your project. A good answer is specific, practical, and tied to real delivery.
Good Ruby on Rails work is easy to maintain, tested, and consistent with the rest of the codebase. You should see clear naming, predictable structure, and careful use of gems and framework features. Strong specialists also explain trade-offs instead of adding complexity by default.
Yes, Rails specialists are often brought in to stabilize older applications, reduce technical debt, and plan version upgrades. This is useful when dependencies are stale, test coverage is weak, or the app has grown beyond its original structure. A careful upgrade plan matters more than speed alone.
