- Established the Process of Record (POR) for wet chemical etching during the transition from M6 to larger G12 silicon wafers, defining process conditions and qualification criteria. - Collaborated with silicon wafer suppliers on seed wafer sourcing, technical evaluation and qualification to support process development. - Led the User Requirement Specification (URS) for a new wet etching tool planned to support production in Bitterfeld, translating process needs into equipment requirements. -Performed ma

- Developed seed wafer preparation and wet etching processes for silicon wafer manufacturing, with a focus on KOH etching and wet cleaning. - Used DOE, SPC and wafer characterization data to troubleshoot variation and define operating conditions. - Supported equipment and process qualification, wafer reclaim activities, documentation and operator training. - Established a process window that reduced seedwafer and wet etching related defects - Machine operation for wet etching and electrochemical etching

- Supported the production ramp and technology transfer of Cu/Sn electroplating processes for interdigitated back contact (IBC) solar cells. - Led process and tool development for a high speed inline electroplating system, working with equipment suppliers to define process requirements and support factory and site acceptance testing (FAT/SAT). - Performed Engineering Change (EC), Process Characterization Review (PCR) and Transfer Copy Review (TCR) activities for the transition to next generation cell tech

- Developed and improved Cu/Sn electroplating processes and equipment for IBC solar cell manufacturing. - Collaborated with tool suppliers to translate process needs into equipment specifications and perform on-site FAT/SAT. - Characterised plating performance, investigated process variation and optimized recipes to support stable production. - Authored and maintained electroplating documentation, including SOPs, recipe specifications, OCAPs, DWACs, PFMEAs and CNTs.

- Part time lecturer for undergraduate chemical engineering subjects at De La Salle University Manila

- Develop and deploy new or modified process formulations, define processing or handling equipment requirements and specifications, and review processing techniques and methods applied in the manufacture, fabrication and evaluation of solar cell. - Lead the process development (DOE, bath characterizations, marathon run) of the 1st MECO plating tool of SunPower for technology transfer from R&D to manufacturing. - Developed the Metrology System Analysis (MSA) qualification of all analytical laboratory proce
