Industrial automation
Industrial automation specialist (30+ yrs)

Hungarian process-control and HMI integrator with deep experience in the food-processing industry — mills, feed mixing, pasta production, silos.

Automation & HMI

Five ways we typically work with clients.

01 / Embedded
Embedded software development

Firmware, device drivers, and application-layer software for microcontroller- and SoC-based products. From prototype through production hand-off.

02 / Automation
Industrial automation

PLC and HMI software, machine integration, sensor connectivity, and connection to higher-level supervisory systems.

03 / Consulting
Engineering consulting

Technical advisory on architecture, technology selection, and hands-on support for in-house engineering teams that need a senior pair of hands.

04 / Support
Long-term product support

Maintenance, feature development, and field-issue resolution for products already in market. Built to keep them shipping.

05 / AI enablement
AI workflow adoption for embedded teams

Helping in-house engineering teams integrate current-generation AI tooling (Claude) into their firmware development practice — practical onboarding, embedded-specific use cases, prompt patterns that work for production code, and the engineering judgement to know where AI helps and where it doesn't.

Senior engineering, directly.

OlingoTech is founder-led. Engagements are run and delivered by the people doing the technical work — no account-management layer between you and the engineering. You get senior attention from the kickoff call onwards.

We operate as a small specialist team with an extended network of trusted subcontractors. This lets us stay senior-heavy on every project and scale capacity for project-based work without the overhead of a large consultancy.

Hungarian operating costs combined with a Western-Europe-aligned engineering culture and full intra-EU invoicing make us a practical fit for Dutch, German, and other EU product companies looking for a long-term embedded partner.
