I'm contributing to EPC design for gold processing plants and tail gas treatment projects at PSI GROUP Companies, including Aqtas, RG Gold, Kogadyr, and Kazzinc JSC.

I develop material balances, P&IDs, PFDs, piping drawings, specifications, data sheets, and hydraulic calculations. I also led a QA audit that confirmed closure of 17 of 19 nodes and resolved an electrowinning-section error.

I use AutoCAD, AutoLISP, Excel, AI, and Python to reduce repetitive engineering work, including automating edits across more than 123 drawings. My Chemical Engineering degree and training in gold extraction technology support my work in hydrometallurgy and ore beneficiation.
