Replaced a nightly batch job with an event-driven reconciliation service that matches bank transactions to invoices within minutes.

Software engineer · Bristol, UK
I build reliable software for teams that ship.
I'm Mira, an independent engineer with twelve years of experience in web platforms, APIs and developer tools. I join product teams for a few months, deliver the hard parts and leave the code better documented than I found it.

How I work
Calm delivery, no heroics
Good engineering is mostly a set of habits. These are the ones every engagement is built on.
More about me- 01
Small, reversible steps
Feature flags, shadow modes and gradual roll-outs. Big-bang releases are where projects go to die.
- 02
Write it down
Design notes, decision records and runbooks are part of the work, not an afterthought.
- 03
Measure first
Performance, reliability and cost are measured before they're optimised.
- 04
Leave a team behind
Success is your engineers owning the system confidently after I've gone.
Kind words
What clients say
“Mira didn't just rebuild the system, she left us a team that understands it. The handover was the best I've seen from a contractor.”
“Calm, clear and thorough. Our receptionists actually asked to keep the weekly demos going after launch.”
“Eight weeks, a clear report and a measurably faster product. Exactly what we hired for.”

Notes from the work
PostgreSQL is a fine queue (until it isn't)
Before adding a message broker to a young product, consider the database you already run. Here's how I build job queues on PostgreSQL, and the signals that it's time to move on.
Why I estimate in ranges, and how clients learned to like it
A single number feels reassuring and is almost always wrong. Ranges with stated assumptions lead to better decisions and fewer awkward conversations.
My first week on a legacy codebase
The checklist I follow when I join a team with years of history in its code: what to read, who to talk to and what not to change yet.
