i’m pasha. i am a data analyst & software developer. i analyze data, tell visual stories, code apps and websites. my stack includes python, javascript/typescript, node.js, react, django; pandas for analysis, plotly/bokeh and d3 for data visualization.

my work in tech is driven by my reflections on tech. i work on projects that deal with the politics of technology, its material/environmental costs, and resistance to the dominance of big platforms.

my work is sculpted by design, visual aesthetics, and storytelling.

open to collaboration. reach out if our visions intersect.

semiconductor emissions explorer

2025 • data

freelance data project for interface’s global chip dynamics programme developing the previous version of the project.

i conceptualized data-driven visual narrative and coded interactive d3.js charts on emissions from semiconductor manufacturing. i was particularly interested in how to translate complex context into coherent storytelling.

explore the interactive charts on the project's website.

the eye with no iris

2025 • reflections

a commission by the civic data lab, presented at silent green, berlin during the data festival.

in collaboration with abstraqt, we produced a video that explores the intertwined roots of modern statistics—and data science—with eugenics. the starting point for the video was our research that galton, pearson, and fisher, referred to as the “fathers of modern statistics,” were also prominent eugenicists.

watch the video in 3 parts on vimeo.

glu festival workshop

2025 • reflections

i talked about tech at an art and music festival glu.
