Field Notes
Practitioner writing on trading, compliance, and regulated platform UX — plus the meta-discipline of running this portfolio as a product. Shorter than a case study, longer than a tweet. Four notes on client work (FIX 4.4, MiFID II, ASIC RG 268, KYC / AML), one on how I read AWStats and fix funnels on my own site.

By topic
The five notes group into three discipline clusters. Pick by what you are actively dealing with.
Cluster 01 · Regulatory UX (3 notes)
How regulation becomes a product input
Each note shows a specific regulatory obligation translated into a shipped UI pattern. The regulation drives the design constraint; the design carries the regulator's intent into every render.

- Why KYC Drop-Off Spikes at EDD FinCEN · FATF Rec 10 · 7 min
Cluster 02 · Institutional Trading (1 note)
Designing at FIX 4.4 latency
When the round-trip budget is 8–12ms, consumer UX patterns are a latency tax. The institutional alternative is a different design playbook entirely.

Cluster 03 · Portfolio Engineering (1 note)
Treating my own portfolio as a product
The meta-track. AWStats funnel analysis on edwson.com applied with the same epistemic discipline I use for client A/B tests. Falsifiability commitment in writing.

Suggested reading order
If you are reviewing this portfolio for a senior product design role, here are three reading paths sorted by how much time you have:
- 8 min Start with Reading AWStats Like a Product Manager — the meta-discipline note. Shows how I read analytics on my own site with product-manager rigor. Read this first if you want to know whether I think like a senior PD before reading the client work.
- 25 min Pair the funnel note with one regulatory note that matches your stack. Buy-side PMs: read MiFID II Best-Execution. Cross-border retail brokers: read ASIC RG 268. Onboarding and compliance teams: read KYC EDD. Institutional execution desks: read FIX 4.4 Latency.
- 90 min Read all five. They cover the breadth — regulatory translation, institutional execution, onboarding conversion, and portfolio engineering as a discipline. Then read Compliance Approach and Data Verification for the methodology pages they reference. That's the full body of practitioner writing on edwson.com.
Why field notes
Case studies do one job — they prove a body of work exists and it shipped. They are the wrong shape for a different job: showing how a practitioner thinks through a specific regulatory or execution problem when it is actively on the desk. Field notes are that shape. One problem, 800–2,200 words, with the pattern I landed on and the ones I rejected.
Most of the notes are about client work — FIX latency, MiFID II best-ex, ASIC disclosure, KYC EDD. One is different: it is about this portfolio itself, and how I read AWStats on my own site the way I would read a product analytics dashboard. Hiring managers reviewing portfolios see two kinds of designers: designers who shipped product, and designers who can articulate why and how they shipped product. Showing the meta-work — funnel analysis, JSON-LD discipline, surgical fixes — is part of articulating the second.
The audience is other practitioners — hiring managers, design directors, and engineers at institutional finance firms who want to know whether the person writing understands the domain deeply enough to argue about it in a review.
What is on the desk next
Three note topics in active drafting. Order will depend on which is most useful at the moment a recruiter asks.
- Methodology Design-as-Governance — A Working Definition A direct statement of what "design-as-governance" actually means in practice — beyond a slogan. The disclosure render event, the audit trail, the precondition gate; what shipped at ACY versus the methodology document. Roughly 2,000 words.
- Methodology Reading a Regulator's Notice — Extracting Design Requirements from Legal Text The actual skill that makes a designer's voice carry weight in compliance reviews. Picking apart an ASIC notice, an ESMA consultation, or a MAS circular. How to spot the operative clause versus the framing.
- Institutional craft Tabular Numerals + Density — Typography for Trader Surfaces Why monospace digits, why tabular figures, why 9.5px micro-text is OK at a Bloomberg-class density, why most trader UIs ignore this and pay the cost. Concrete OpenType feature flags and the design tokens.
