Challenges & Solutions

Dynamic Route Matching

Built a regex-based routing engine resolving path params, query strings, and wildcards in under 10ms — supporting Express-style route syntax without a backend server.

Nested Schema Persistence

Modeled nested JSON schemas as flat key-path records in PostgreSQL, enabling efficient querying without losing structural integrity or requiring JSONB full scans.
