Sinyangwe started his career at
PolicyLink with the Promise Neighborhoods Institute. As protests emerged in the wake of the 2014
shooting of Michael Brown in
Ferguson, Missouri, he connected with Ferguson activists online. Sinyangwe built projects including a database of police killings, Mapping Police Violence, and a platform of policy solutions to end police violence called
Campaign Zero. Sinyangwe also serves as a data scientist for OurStates.org, a project focused on state legislatures and with Mckesson and
Brittney Packnett founded the
Resistance Manual, an open-source project aimed at connecting anti-racist activists with activists focused on intersecting issues. He has also been responsible for a number of
CPRA requests for RIPA-formatted police stops data through the non-profit organization
MuckRock. During the
2016 U.S. Presidential campaign, Sinyangwe and colleagues met with Democratic candidates
Bernie Sanders and
Hillary Clinton on these policy issues. He has been a vocal critic of the "
Ferguson Effect", using data to refute the theory that policing had diminished and crime increased in face of activist scrutiny of police use of force.
Melissa Harris-Perry has compared Sinyangwe to journalist and anti-
lynching activist
Ida B. Wells, noting that Wells began her work by "compil[ing] the data, the social science and research about how, when and where lynchings were happening to begin to make it stop." The podcast particularly focuses on race, grassroots activism, discrimination and other forms of inequality; recommending

GQ, June Diane Raphael of
How Did This Get Made? wrote, "The stories they uplift and think critically about are the ones I'm now wondering why I've never been exposed to/exposed myself to." Sinyangwe has also been featured on
CNN,
MSNBC,
BBC News,
FiveThirtyEight,
The Los Angeles Times, and other publications. He has written for the
Huffington Post and
The Guardian. ==Awards and fellowships==
