Owen Perry — independent product engineer for small fintechs and funds.
e7n is a one-person practice. No team page, no account layer. Senior delivery, end-to-end, one engagement at a time.

Fifteen years inside trading, exchange, and fintech platforms.
I started in fixed-income analytics at FactSet in San Francisco, spent three years in trading operations at NASDAQ in Stockholm, and the following decade working inside institutional trading and investment platforms — Itiviti, Quod Financial, AiX, Broadridge, Onyx Capital Group, Tradeteq, and a handful of independent engagements. The job was always the same: take unclear requirements, regulated constraints, and impatient stakeholders, and ship working software.
e7n is the independent version of that. The focus is narrower: automation, integration, and internal tooling for small fintechs, funds, and trading desks that need senior delivery without a programme team. The work is faster, less political, and closer to the people actually using the software.
Four principles.
- 01
Ship first, polish second
Working software beats long plans. The first sprint produces something that runs against real or realistic data, not a slide deck.
- 02
Auditable by default
Every automation and integration is built with logs, change control, and a clear handoff to compliance. If an auditor or regulator asks, the evidence is already there.
- 03
One operator, accountable end-to-end
No account manager in front of the engineer. The person writing the code is the person on the call and the person writing the post-mortem.
- 04
LLM-accelerated, human-validated
LLM tools accelerate coding, testing, and documentation. Diffs are still reviewed line-by-line, tests are still run, and nothing confidential leaves your tenancy without written approval.
Representative outcomes, anonymised where required.
