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.

2026-05-11 · Portfolio engineering · Funnel analysis Reading AWStats Like a Product Manager My second-most-visited page had an 84.6% exit rate. The AWStats data showed exactly where the funnel leaked. Three surgical fixes — a first-screen CTA, a sidebar nav link, and a dedicated bridge section — repositioned a 156-entry catalog page as a feeder to four case studies. Read note → 2026-04-18 · KYC · AML · Onboarding Why KYC Drop-Off Spikes at EDD The baseline KYC funnel works. Enhanced Due Diligence is where it falls apart. The fix is not to shorten a regulatory requirement — it is to change how the questions are presented. Read note → 2026-04-15 · ASIC · Cross-border disclosure ASIC RG 268 Cross-Border Disclosure — Three UX Patterns ASIC RG 268 requires retail clients to see jurisdiction-specific disclosures before each transaction. Three patterns keep recurring. One of them wins in production almost every time. Read note → 2026-04-08 · MiFID II · Best execution Designing MiFID II Best-Execution Reports for Buy-Side PMs MiFID II Article 27 forces firms to prove best execution. The default output is a PDF nobody reads. Here is what a portfolio manager actually needs on the screen. Read note → 2026-04-01 · FIX protocol · Institutional trading Why FIX 4.4 Latency Dictates Order Entry Form Design When an order ticket has a 10ms round-trip budget, the whole form-design playbook you learned from consumer apps goes in the bin. At ACY Securities I spent four years inside that disorientation. Read note →

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.

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:

  1. 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.
  2. 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.
  3. 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.
