The loss of his mobility made Da Silva acutely aware of the difference between accessible and inaccessible spaces. Routines like taking the subway became impossible and favorite spots to meet with friends became unreachable. Da Silva made a documentary, When I Walk (available on Netflix), about his battle with MS and his gradual loss of mobility.
Wanting to do more than document the challenges he faced, Da Silva set out to take concrete action that would make it easier to get around with a disability. Together he and his wife, Alice Cook, created AXSmap, a crowdsourced map to rate businesses based on how accessible they are.
