Lynn Amacher
I build reliable backend systems, APIs, and data pipelines — with a focus on performance, maintainability, and the kind of clarity that makes the next engineer's job easier.
— ABOUT
I'm Lynn Amacher, a software engineer based in Illinois. I specialize in front end/back end systems — scalable APIs, data pipelines, and the infrastructure that keeps production stable at 3am.
I care deeply about readability, testability, and the long game. The code I write today should be easy to delete in two years when requirements change — and it usually is.
I build software the way I build everything else — with care for the people who have to live with it later. That means clean, well-tested code, sensible architecture, and documentation that doesn't leave the next developer guessing. I hold AWS and Azure cloud certifications, along with certifications through freeCodeCamp, and bring a design background that shapes how I think about usability and structure. Whether it's a backend service, a database schema, or a full deployment pipeline, I build for reliability first — systems that work quietly, scale cleanly, and don't need constant babysitting.

— WHAT I DO
I take on contract and freelance work across backend, systems, and data engineering. Tight scopes, clear deliverables, and communication that doesn't require a translator.
Python-driven services and business logic — reliable, well-tested, and built to scale.
Schema design, queries, and data modeling — structured, efficient, and easy to maintain.
REST endpoints and third-party connections — systems that talk to each other cleanly.
Deployment, hosting, and infrastructure — production-ready and built to stay up.

— How I Work
We align on goals, audience, constraints, and creative direction before a pixel is moved.
I map the plan — scope, deliverables, timeline, and any technical architecture needed.
Design and build happen in clear rounds with client review checkpoints built in.
Final delivery, handoff documentation, and post-launch support — all included.
