OVERVIEW

What I built

Clear hierarchy, premium spacing, and room for evidence—optimized for skimming and depth.

This page is intentionally structured like a SaaS-grade case study: clear hierarchy, readable typography, and room for proof.

DECISIONS

Decisions & trade-offs

Layered architecture for maintainability

Layered architecture chosen over tightly coupled service logic to keep the system maintainable and evolvable.

Clean abstractions over short-term speed

Preferred clean abstractions and boundaries even when it increased upfront implementation time.

Relational modeling for consistency

Relational modeling chosen over denormalization to preserve consistency and correctness across workflows.

ARCHITECTURE

System design

Service + Repository architecture

Clear separation between application services and persistence concerns.

Domain-driven entity modeling

Domain entities modeled to support investment-related workflows.

PostgreSQL relational persistence

Relational persistence layer supporting production-grade data workflows.
