Project history

Independent Mechanical Engineer

Independent Mechanical Engineer
Delivering engineering work packages for process systems, industrial machinery, and hydrogen/CO2 clean technologies. Executing 2D/3D CAD modeling, engineering calculations, prototyping, testing, and linear static FEA. Conducting design reviews, equipment specification, technical documentation, risk assessments, and CE compliance.

Senior Mechanical Engineer

Skytree
Part of a multidisciplinary team scaling a modular 1 ton/day Direct Air Capture (DAC) system integrated into six 20 ft containerized skids. Reviewed P&IDs for the second-generation (Beta) system, specifying and sizing equipment, instrumentation, valves, and fluid-handling components. Co-designed a water-heated vacuum vessel operating at 60 mbar(a) and 120 degrees C. Designed, tested, and manufactured a first-of-its-kind vacuum dosing valve for bulk sorbent handling in Direct Air Capture systems. Conducted linear static FEA on structural frames, skids, and lifting points using ANSYS 2025 R1.

Senior Mechanical Engineer

HyET Hydrogen
Delivered the company's first CE-marked H2 compressor, compliant with PED and Machinery Directives; EN 13445 design up to 500 bar / 10,000 cycles and EN ISO 12100 risk assessment. Engineered high-pressure H2 balance-of-plant subsystems including piping, humidifiers, dryers, and cooling loops. Led junior and mid-level engineers, coordinating daily engineering activities, resource allocation, and project priorities. Implemented the company's first PDM system. Designed and commissioned a 150k euro high-pressure H2 test station (FAT/SAT). Scaled key component manufacturing from prototype to series production (>6,000 units) via photo-etching, laser cutting, CNC milling, and turning. Conducted linear static FEA of skids, pressure components, and machinery parts using SOLIDWORKS Professional 2021.
