Five steps from a problem to its solution.

Help me design and build a first working prototype for this problem in Mumbai, Maharashtra, India.

Problem: Families in Mumbai caring for someone newly diagnosed with dementia can't find trained caregivers or a memory clinic close to home.
Who it hurts: Adult children and grandchildren in Mumbai and its suburbs looking after an older relative with dementia, often for the first time.
The moment it hurts: The weeks after diagnosis, when the family needs a trained carer, therapy sessions and advice, and the only dedicated government memory clinic may be across the city.
What people do today: Families ask agencies, friends and relatives; agencies often have no staff trained in dementia care, and regular therapy means repeated journeys across the city.
Why it is still unsolved: Memory clinics, day care, therapists and trained carers are run by different hospitals, NGOs and agencies, there is no public list by area, and Maharashtra's district memory clinic OPDs are not listed by location. Unlike palliative care, dementia care is long, continuing and mostly at home.
What solved looks like: A free directory for the Mumbai region, searchable by suburb, listing memory clinics, dementia day care, therapists and agencies with dementia-trained carers, with cost, languages and how to get a referral, plus a short guide for families in the first month after diagnosis.
Where: Mumbai, Maharashtra, India

First, list what you would need to learn from the people affected before building, as interview questions.
Then propose the simplest version that would help, the screens or messages it needs, and the data it would use.
Keep it cheap to run, accessible, and respectful of people's privacy. Flag anything you are unsure about instead of guessing.
