Software engineer resume examples for senior, staff and more

Stackmere · Sydney, NSW

Platform group of 14 engineers behind the API, notifications and integrations of a B2B operations product used by about 1,400 business customers.

• Redesigned the request pipeline across six TypeScript and Node.js services, adding connection pooling, request coalescing and a read-through cache; p95 API latency fell 38% at a peak of about 2,300 requests a second.
• Defined service-level objectives, dashboards and a blameless incident review format for the platform group; repeat production incidents fell 27% over the following three quarters.
• Led the staged move of 41 internal API consumers to a versioned gateway, using traffic mirroring and per-consumer feature flags, with no customer-facing incidents during the six-week cutover.
• Owned alert routing and deployment runbooks for the platform's AWS services and took the primary on-call shift one week in five.
• Profiled memory growth in the notifications service, fixed two leaks in stream handling and retired a nightly restart that had been in place for over a year.
• Mentored three engineers through service ownership, code review and their part in the staged platform rollout.

Tools: TypeScript, Node.js, AWS, PostgreSQL, Redis, OpenTelemetry, Grafana

Palletbase · Sydney, NSW

Data import team at an inventory platform where customers upload supplier catalogues of up to 500,000 rows.

• Rebuilt catalogue imports as asynchronous workers with chunked processing, shortening the median large import from 42 minutes to 19 minutes.
• Added idempotency keys and resumable checkpoints so a failed import restarts where it stopped instead of from the first row.
• Added downloadable row-level error reports so customers could fix rejected rows themselves instead of raising a support ticket.
• Created release checklists and shared integration fixtures that four product squads adopted for their own services.
• Took part in on-call, design reviews and staged releases for the data services.

Tools: Node.js, TypeScript, PostgreSQL, AWS Lambda, GitHub Actions

Palletbase · Sydney, NSW

Graduate program with rotations through customer integrations and internal tools.

• Built a CSV validation library in TypeScript that customer support used to diagnose failed uploads before escalating to engineering.
• Wrote the first end-to-end tests for supplier onboarding, covering the six file layouts customers sent most often.
• Documented the retry behaviour of the supplier sync job after shadowing the on-call engineer for a week.

Tallyfern · Melbourne, VIC

Five-person squad that owns customer onboarding for a small-business accounting product.

• Shipped eight React and TypeScript onboarding changes, including a redesigned business-details step that support had flagged as the top source of setup tickets.
• Built a Node.js check for ABNs and duplicate business names at sign-up; duplicate records fell 21%.

Capstone project, team of four · React, Express, PostgreSQL, Prisma, Playwright

Events, registrations and waitlists for student clubs; used by three clubs in semester 2.

• Designed the REST API and PostgreSQL schema for events, registrations, waitlists and permissions.
• Wrote the waitlist logic inside database transactions so two students could not claim one freed place.
• Added Playwright tests for sign-up, cancellation and waitlists, run in GitHub Actions on every pull request.

Tiderow · Sydney, NSW

Billing platform team of seven engineers; owns the invoicing, entitlements and webhook services.

• Reworked the invoice API query plan and caching layer, reducing p95 latency from 820 ms to 460 ms across about 1.6 million requests a month.
• Moved webhook delivery to a queue-based worker with retries and a dead-letter queue; failed deliveries needing manual replay dropped from about 40 a week to three.
• Introduced consumer-driven contract tests between billing and the entitlements service, which caught 11 breaking changes before release in the first two quarters.
• Wrote the design document and rollout plan for moving 38,000 accounts to usage-based invoices, including two cycles of shadow billing that compared old and new invoices line by line.
• Added structured logging and trace context to the invoice and webhook services, cutting the median time to find a failing request during incidents from about 25 minutes to six.
• Mentored two engineers through their first on-call rotations, pairing on incident reviews and runbook updates.

Corella Commerce · Sydney, NSW

Order management team at an e-commerce platform used by about 2,000 independent retailers.

• Cut the nightly order export from 3 hours 10 minutes to 48 minutes by batching queries and adding two composite indexes.
• Took part in the checkout and orders on-call rotation and led three post-incident reviews.

Tools: JavaScript, Node.js, PostgreSQL, OpenAPI, GitHub Actions

Emberlane Health · Brisbane, QLD

Appointment booking and patient messaging platform; staff engineer across five product squads and the platform team, about 40 engineers in total.

• Set the API platform roadmap after an audit found 23 separately maintained integrations; moving them onto shared modules cut duplicated integration work by 34%.
