AI raised the floor for everyone. Knowing the product, the users and the constraints is what raises the ceiling.

From the first interaction
to the system behind it.
I connect thoughtful interfaces with dependable systems. 5+ years building full-stack products across utilities, healthcare, and HR technology.
Senior Product Engineer @ Smart Energy Water
Reusable interfaces. Predictable state. Cross-platform experiences.
¹ Results from my work on American Water at Smart Energy Water.
A Claude connector that writes, schedules, publishes, edits and deletes LinkedIn posts. Tell Claude “post this Monday at 9 am” and close the laptop. It goes live on time.
Draft the post with Claude, then say when it should go out: now, or Monday at 9 am.
Postline in half a minute: write in Claude, Postline holds it, it goes live on time. Every frame and every note was made in code.
AI raised the floor for everyone. Knowing the product, the users and the constraints is what raises the ceiling.
A wrong requirement gets you a beautifully tested wrong product. Deciding what “correct” means is still the engineer’s job.
In Postline, the tools were the easy part. OAuth, token lifetimes, retries that never double-post and LinkedIn’s rules were the real work. That part comes from experience.
