Five steps from a problem to its solution.

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

Problem: Homebuyers in Gurugram who won a refund at HRERA can't track whether, or when, the money is actually being recovered from the builder.
Who it hurts: Families in Gurugram who paid for delayed or undelivered homes and hold HRERA orders for refunds or penalties that the builder hasn't paid.
The moment it hurts: Years after winning their case, still waiting, and learning from the news that their builder's accounts may have been frozen.
What people do today: Recovery is run by sub-divisional magistrates and tehsildars, and homebuyers are told to approach these officials for the status of their recovery.
Why it is still unsolved: Each recovery certificate moves through revenue offices, not the regulator, and there is no public view of where a certificate stands, so buyers chase officials one by one.
What solved looks like: A public tracker of HRERA recovery certificates in Gurugram, by builder and project, showing the amount due, the action taken (notice, account frozen, property attached) and the amount recovered, with alerts to the homebuyer when their case moves.
Where: Gurugram, Haryana, 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.
