At Primrose Bio, I support protein purification workflows through clarification, filtration, chromatography, AKTA FPLC, and fermentation bioreactor operations. Previously at Pfizer and Eitr Biologics, I purified and characterized recombinant proteins and biotherapeutic antibody drug candidates.

I also build and maintain websites for U.S.-based clients, managing projects independently from requirements through delivery. My work combines molecular biology, analytical chemistry, and full-stack web development.
