Problem: Healthcare SaaS had 42s initial load times and inconsistent backend performance.
Solution: Designed distributed caching (Redis/LazyCache), optimized queries with EF Core + CQRS/Mediator.
Impact: Load time reduced to 200ms (99.5% faster).
Problem: Clients required secure, multi-tenant authentication across products.
Solution: Integrated Azure AD B2C & Keycloak for enterprise-grade identity.
Impact: Ensured tenant isolation & compliance, scaled across multiple clients.
Problem: Manual reporting & overtime approvals were time-consuming and error-prone.
Solution: Built job scheduling framework with Quartz & Hangfire.
Impact: Saved ~30+ hours/month, ensured 100% on-time reporting.
Problem: APIs slowed under peak load.
Solution: Optimized EF Core queries, added caching, introduced FastEndpoints.
Impact: Average API latency cut by 40%, improved scalability.
Problem: Knowledge gaps among juniors slowed delivery.
Solution: Conducted code reviews and Clean Architecture/DDD workshops.
Impact: Raised coding standards, improved delivery quality.
