Ledger

A date rail down the start edge. Fifteen years scan in one pass.

Karen Whitfield

Operations Manager

Profile

Operations manager with fifteen years keeping supply chains and back offices running quietly. I find the step everyone works around, remove it, and write the process down so it stays fixed. Comfortable with a warehouse floor, a spreadsheet, and a room of vendors on the same day.

Recommendations

Karen has fixed problems I didn't know we had, and I only found out because the complaints stopped.
Gerald Simmons · Director of Operations
Aisha Karim · Warehouse Supervisor

Every date sits in a fixed rail down the edge of the page, so a long career reads as one vertical timeline instead of a stack of paragraphs. Single column, no tables, no colour — the safest thing you can hand an applicant tracking system.

Lea Fontaine

UX Designer

Profile

UX designer working where research meets craft. Seven years designing complex tools, the kind with a thousand states and no room for decoration. I earn the layout by watching people use the old one, and I care as much about the empty states as the happy path.

Experience

UX Designer

Studio Verano2020 to Present
  • Redesigned a data-heavy analytics product; task success in usability tests rose from 61% to 88%.
  • Built the pattern library that keeps four squads visually consistent without a weekly design police meeting.
  • Run the research practice: interviews, tests, and a shared archive the whole team searches.

Product Designer

Field & Frame2016 to 2020
  • Took features from sketch to shipped UI for early-stage clients across fintech and health.
  • Introduced prototyping to the pitch process, which cut post-launch rework noticeably.

Recommendations

Lea designs the parts nobody demos: the errors, the empty screens, the edge cases. It shows.

Profile

QA automation engineer who thinks quality is a design problem, not a gate at the end. Six years building test suites people trust enough to ship on. I chase flaky tests like bugs, keep the pipeline fast, and I would rather prevent a defect than log a pretty report of it.

Experience

QA Automation Engineer

2021 to Present
Northloop Software
  • Built the end-to-end suite that gates every deploy; caught regressions that had been reaching production monthly.
  • Cut CI runtime 55% by parallelizing tests and killing the flaky ones instead of retrying them.
  • Pair with developers on testability so bugs get designed out before they are written.

QA Engineer

2017 to 2021
Proving Ground Games
  • Owned release testing for a live product with weekly updates and zero tolerance for save-corruption bugs.
  • Wrote the first automated smoke tests, replacing a two-hour manual checklist before each build.

Marcus Bello

Senior Software Engineer

Profile

Backend-leaning full-stack engineer with nine years building and scaling web services. I like taking a slow, flaky system and making it boring: clear boundaries, good tests, and dashboards that tell the truth. Comfortable owning a feature from database schema to production rollout.

Experience

Senior Software Engineer

Larkfield Systems
2020 to Present
  • Re-architected the billing service around an event queue, cutting failed charges by 40% and making retries auditable.
  • Cut median API latency from 480ms to 120ms by profiling hot paths and adding a read-through cache.
  • Mentor three engineers and run the team's design-review rotation.

Software Engineer

Cartwright Commerce
2016 to 2020
  • Built the checkout API serving 2M orders a month across web and mobile clients.
  • Introduced integration tests to a legacy codebase, taking release rollbacks from weekly to rare.

Marcus is the person you want on the incident bridge: calm, fast, and he fixes the cause, not the symptom.
