What I'm looking for

I am seeking backend roles focused on API design, integrations, automation, and CI/CD in collaborative teams that value testing, mentorship, and measurable improvements.

I am a backend software engineer with six years of experience building and scaling web applications across sales, insurance, finance, healthcare, and e-commerce industries. I specialize in Python frameworks like Django and FastAPI, and I focus on designing robust REST APIs and automation to improve team throughput.

At Logical IT I led development of scalable APIs and serverless services, authored Python playbooks to enforce coding standards, and reduced PR review time by 80% while automating integrations to cut manual effort by about 75%.

Previously at InvoiceSherpa I implemented third-party integrations (QuickBooks Online, Stripe, PayPal), improved backend stability with automated tests, and worked with GCP services to enhance scalability and data handling. I have a track record of improving test coverage and preventing regressions.

I mentor junior engineers, host technical talks, and design CI/CD pipelines using GitHub Actions. I seek opportunities where I can drive API design, automation, and reliable deployment practices to deliver measurable operational improvements.
