Backend work that ships — and keeps running.

I build and improve API integrations, third party integrations, data workflows, and backend systems. Clear scope, clean implementation, and verification you can trust.

Work directly with Julian Baker — principal software engineer. Practical deliverables, straightforward communication.

How engagements typically work

Clear milestones first, then build. You can stop or continue based on results.

Start
short brief + call
Scope
defined deliverables
Build
implementation + tests
  • I’ll propose a small, concrete first milestone so you can evaluate quality quickly.
  • If something is already broken, we can triage first — but the goal is a stable system, not perpetual firefighting.
  • I can work project-based or on a small ongoing retainer for maintenance and improvements.
Defined scope
You’ll get a written plan: what’s included, what’s not, and what “done” means.
Verification
Changes are validated with tests, logging, and simple acceptance checks so you can trust the result.
Maintainability
I leave systems easier to operate: clearer code, docs, and predictable deployment/runtime behavior.

A real engineer working with you

I’m Julian Baker — a PhD-trained engineer building backend systems and Python automation for real businesses. I focus on clear scope, solid implementation, and the operational details that prevent surprises later. If you need a reliable backend partner for a small project or an ongoing system, you work with me directly.

What PyCoreOps does

API development
Design and build REST APIs, authentication, role-based access, and clean request/response contracts.
API integrations
Connect third-party services (payments, CRM, email/SMS, Shopify, Google APIs). Webhooks, retries, idempotency, rate limits.
Backend development
Build backend features: business logic, databases, background jobs, admin tooling, internal dashboards.
Data pipelines & ETL
Imports/exports, CSV/Excel automation, validation, transformations, scheduled jobs, monitoring and alerts.
Automation & internal tools
Python automation for recurring operational tasks: reporting, reconciliation, data cleanup, workflow glue.
Maintenance & reliability
Fix root causes, reduce recurring failures, add logging/metrics, and make deployments more predictable.

Simple process, professional output

1
Send a short brief
Text a few lines: what you want built, current stack, and the deadline (if any).
2
Clarify scope
We align on deliverables, constraints, and a first milestone you can approve quickly.
3
Build + review
I implement, add tests/verification, and show you the result with a clear handoff.
4
Operate confidently
Optional: I can stay involved for maintenance, improvements, and reliability updates.
What to text me (copy/paste)
1) what you want built / improved
2) your stack (Python/Node, DB, hosting)
3) any constraints (deadline, budget range, access)

Not hype. Just solid engineering.

  • No inflated promises — clear scope and deliverables.
  • Practical communication: what I’m doing, why, and how we’ll verify.
  • Built for real operation: logs, monitoring hooks, and predictable behavior.

Especially useful for teams that need backend momentum without hiring

  • You need an API or integration done correctly (and documented).
  • You want automation that saves time every week (not a fragile script).
  • You inherited backend code and need it stabilized and made maintainable.
  • You want a single accountable engineer instead of a marketplace.

Have a backend project? Let’s scope a first milestone.

Text a short brief and your stack. I’ll reply with questions (if needed) and a proposed first deliverable.

If I miss you, I’ll text back when available.PyCoreOps • backend engineering & Python systems • Tampa Bay + remote (US)
