Custom internal tools & data systems.

I design and ship the internal software your team actually uses every day — operator dashboards, ingestion pipelines, dense data UIs, and the database logic underneath. No marketing sites. No CMS rebuilds.

Database logic

Schema design, RLS policies, query optimization, audit trails. Postgres-first systems built for correctness under load.

Workflow optimization

Internal automations, ingestion pipelines, scheduled jobs, ops dashboards. Replace spreadsheets with deterministic systems.

Interface design

Dense, keyboard-friendly interfaces for power users. Inline edits, drag-resizable grids, kanban, fast list views.

§02Case Studies / Production Systems

Five interaction patterns lifted from three production systems — a loan processing pipeline, a pipeline triage dashboard, and a financial operations console.

CS-01● production spec

Resizable dashboard grid

Persistent layout memory across sessions

Problem
Operators needed one screen showing live loans, dates, contacts — without scrolling between modules.
Move
Persistent drag-resize grid where each panel is an independent data surface; layout saved per user.
Result
Triage time per file dropped from minutes to seconds; zero tab-switching for daily review.

CS-02● production spec

Inline edit everywhere

Zero-modal optimistic data entry

Problem
Every field change required opening a modal, breaking flow and discouraging cleanup of stale data.
Move
Click-to-edit on every cell with optimistic writes, validation on blur, and undo on conflict.
Result
Data freshness up. Modals reserved only for destructive or multi-field operations.

CS-03● production spec

Mobile kanban + floating notes

Touch-native drag and drop architecture

Problem
Field staff carry context in their head; desktop-only tools meant nothing got logged in the moment.
Move
Touch-first kanban with attachable floating notes that pin to a record and travel with it across stages.
Result
Logging happens at the point of work; managers see status without asking.

CS-04● production spec

Status-rail pipeline table

Algorithmic color-coded aging logic

Problem
Operators scanning a long loan pipeline couldn't tell at a glance which files were aging or stagnant.
Move
A 3px color rail on every row driven by a pure aging function (clean / aging / stagnant), paired with tabular-nums columns and conditional text color on days-in-milestone.
Result
Triage is peripheral-vision work — no badges to read, no sorting required to see what's slipping.

Row-Level Security Architecture

Strict query-level tenant isolation

Problem
Managing a high-volume pipeline meant mixing field staff, desk operators, and managers in one system without exposing restricted borrower financials.
Move
Architected a multi-tenant relational database utilizing strict Row-Level Security (RLS) policies to isolate user views at the query level.
Result
Total data compliance. Users only see the exact files and fields they are authorized to act on, with zero front-end latency.

Interface teardowns

Component-level friction analysis

Off the shelf software forces your team to adapt to generic layouts so I run full teardowns on your existing internal tools to identify EXACTLY where your operators are losing time to unnecessary clicks and modal windows.

§04Engagement / Upwork

All engagements run through Upwork.

Contracts, scope, milestones, and billing stay inside the platform — verified history, escrowed payments, and a clean paper trail for both sides. Send a short brief through the profile below and I reply within 48 hours.
