Aveline Quigley — Backend Engineer

now


Backend engineer in Manchester. I build Go services that sit in front of Postgres and push the slow work onto a queue, and I have a strong preference for boring systems that never page anyone at 3am.

Most of the job is unglamorous. Getting the schema right before there is data in it, keeping transactions short, making retries idempotent, deleting the endpoint nobody has called since 2023. The interesting part of backend work is usually the part users never see.

Stack

Day to day:

  • Go — HTTP services, queue workers, the occasional small CLI
  • PostgreSQL — schema design, query plans, migrations that can be rolled back
  • Redis / NATS — job queues, rate limits, distributed locks
  • Docker, systemd, Terraform for the layer underneath

Comfortable enough with:

  • Python for one-off scripts and data repair
  • SQLite when a service genuinely does not need a database server
  • Prometheus and Grafana, plus enough OpenTelemetry to answer "why is p99 bad"

Opinions I hold quietly:

  • Foreign keys are not optional
  • A queue without a dead-letter path is a data-loss incident waiting for a bad Tuesday
  • If a migration cannot be reversed, write down what happens when it fails at 40%
  • SELECT * in application code will eventually cost you an afternoon

Projects

tickpost — a single-binary CLI for sticky notes and todos, backed by SQLite. Built it because every note app I tried wanted an account, and I mostly wanted to type one line and get on with the deploy.

pg-cookbook — the Postgres snippets I kept re-deriving from scratch: window function patterns, indexing notes with the query plans that justify them, and a migration template that survives being run against a live table.

go-cloud-skel — the minimum viable Go service skeleton. Config from the environment, structured logging, a health endpoint, and a graceful shutdown that actually drains in-flight requests instead of pretending to.

go-queue-worker — a queue consumer with exponential backoff, jitter, and a dead-letter escape hatch. The five things every worker I've written needed: pull, try, back off, give up after N tries, put the body somewhere I can find it at 2am.

sql-migrate-runner — a small CLI that reads SQL files from a directory and runs them in order, tracking applied versions in a schema_migrations table. Transaction per migration, roll back when you need to. I wrote it because psql and a spreadsheet is not a migration strategy.

None of these are frameworks. They are the files I stopped wanting to rewrite.

What I am reading about

Currently working through the Postgres 17 release notes properly rather than skimming them, mostly for the incremental backup and EXPLAIN changes. Also slowly rewriting an internal worker pool now that errgroup and structured concurrency have made most of my old channel gymnastics unnecessary.
