PORTFOLIO
Jacob Scott Hamling
Software + analytics developer building practical systems for insurance and financial workflows.
I build internal web apps, automation, and applied modeling tools that reduce turnaround time, improve data quality, and enable better decisions. I’m especially interested in product-grade workflow design, clean data pipelines, and measurable business impact.

About
A concise view of what I build and what I optimize for.
Professional focus
I like projects where engineering quality directly translates into business outcomes: fewer handoffs, cleaner data, and faster decisions. My work has centered on internal workflow systems (portals, approvals, auditing), automation modernization, and applied modeling for operational support.

Working knowledge
Labels are intentionally conservative and updated as I ship work.
Strengths
- Shipping internal tools with clear workflow states and auditability
- Data validation + quality improvements that reduce downstream rework
- Integrations that handle nested data and auth patterns cleanly
Also working on
- Sharper UI/UX systems for internal portals
- More repeatable deployments and CI habits
- Stronger evaluation discipline for modeling MVPs
Projects
A curated mix of work and personal builds, organized for quick scanning.
Policy Change Request Portal
Internal policy change intake, review, and approvals with audit-ready tracking.
- Workflow states: submit → review → comment → approve with live status visibility.
- In-browser PDF preview/approval to streamline document review and reduce tooling overhead.
- Central dashboard for request status, agent details, and audit history.
