Precision Manufacturing and Operational Management

Industrial Product Design

Applying a designer's empathy to manufacturing challenges, from component layout to full system integration.

Production Leadership

Leading teams and orchestrating complex assembly lines for aerospace-grade output and on-time delivery.

System Optimization

Engineering processes for peak performance, minimizing friction, and maximizing throughput across all stages.

Core Principles

Integrated Operational Leadership

ABOUT

Build better. Improve continuously.
Keep moving forward.

Hello there,
My name is Mantas, and I’m an Operations Manager with a background in industrial design and manufacturing.

Today, I focus on leading production, improving processes, developing teams, and finding practical solutions to complex operational challenges.

My design background still shapes how I approach problems — with curiosity, creativity, and a strong drive to turn ideas into things that actually work.

Production Management

Managing daily operations, priorities, output and delivery.

Continuous Improvement

Simplifying processes, improving production flow and developing practical solutions.

People & Leadership

Building capable teams, creating clear responsibilities and helping people work effectively together.

Problem Solving

Turning operational challenges into structured actions and measurable improvements.

Digitalisation & Transparency

Using data, visual management and digital tools to make production easier to understand and control.

PROCESS

Working Across Languages & Cultures

Manufacturing is ultimately about people — and my working environment is highly international.

I speak Lithuanian, German, English and Russian, and use several of these languages regularly in my work.

German is the main language of daily operations, while Russian helps me communicate directly with members of our multicultural production team who have limited German. English is frequently used when working with our international customer.

Being able to move between languages helps me bridge communication gaps between the shop floor, management and the customer — especially when problems need to be understood and solved quickly.

Aircraft Manufacturing

Working in aircraft manufacturing has taught me that operational improvement cannot come at the expense of discipline and reliability.

Production involves complex assemblies, technical documentation, changing priorities and close coordination between multiple departments and the customer.

My role is to bring these elements together and create a production environment that is structured, transparent and capable of continuously improving.

Industrial Design and Prototyping

Amphibious velomobile

This is a typologically unique vehicle. It is a lightweight, amphibious hybrid vehicle. It is not intended for high speeds, so It fits with ease and comfort into the "electric bicycle" category, so the primary source of power is human muscules, by pedalling and is assisted with electric motors. It can be an all-wheel drive. Eye-catching, award-winning design, and unique features make this creation an excellent vehicle for recreational activities.
