Spearheading the design of a novel orthopaedic implant system within a structured medical device engineering process, working alongside senior product development and verification engineers. Conducted clinical stakeholder interviews to capture requirements, translating findings into verifiable engineering specifications, a design control matrix, and a QFD-anchored design input framework. Developing a novel implant architecture for additive manufacturing, supported by analytical models at component and system level and iterative FEA-driven geometry refinement to meet biomechanical performance targets. Designing a mechanical verification programme to ISO/ASTM standards, encompassing compression testing, force-displacement characterisation, and kinematic validation against physiological benchmarks.

Engineered a temperature-controlled sample stage for a precision optical instrument, owning the full product development cycle from requirements capture to tested first prototype. Developed and verified a parametric thermal model to optimise cooling system design, confirmed through FEA simulation against thermal performance targets. Designed, CNC-machined, and assembled a functional prototype integrating custom aluminium components and a closed-loop liquid cooling system. Characterised thermal cycling performance across heating and cooling profiles, quantifying system behaviour to guide continued product development.

As part of a €493M railway electrification project in Lithuania, resolved design interferences between civil, electrical, and mechanical engineering teams, arbitrating technical conflicts to maintain compliance with EU EN 50163 and Lithuanian railway electrification standards. Working with Autodesk BIM, detected and corrected discrepancies in electrification design schematics, eliminating construction misalignment risks and cutting design approval time by 20%. Additionally assessed third-party infrastructure proposals against railway electrification routes, negotiating with public agencies and municipal authorities to resolve conflicts and secure the necessary project approvals.

As part of the LUREG research group, resolved structural instability in a wave energy converter prototype through root cause analysis, fabricating custom mounting brackets that improved structural integrity and reduced assembly time by 30%. Instrumented a hydrodynamic test rig with precision wave gauges, calibrating NI DAQ-based sensor and transducer systems to capture wave height data upstream and downstream of the energy converter. Executed wave tank testing on a 1:100 scale TALOS wave energy prototype, acquiring wave height, force, and energy conversion data via LabVIEW real-time data acquisition.
