I help growing businesses fix workflows that have become hard to run.
I'm Hanif Carroll, a technical consultant and product engineer with more than eight years of experience building web, mobile, automation, and AI systems.
I'm based in Buenos Aires, work US hours, and contract with US clients through my LLC, HC Studio.
One person from the first conversation through handoff.
I work directly with founders and operators from the first conversations through product decisions, implementation, and handoff.
That continuity matters when the workflow spans people, software, data, business rules, and decisions that can't be handed between separate teams without losing context.
What you can expect from me.
I listen for the context behind the request
The first conversation is about how the business runs, who depends on the system, and what would make a meaningful difference.
I make the tradeoffs visible
I explain the options, costs, and risks in plain language so you can make a decision without guessing what the technical details mean.
I keep decisions close to the build
The person who learns the business problem stays involved through product decisions, implementation, review, and revision.
I leave a clear path forward
You leave with the system, documentation, decisions, and next steps needed to operate it or keep improving it.
Experience across consulting and product teams.
My background covers large delivery environments, product-led teams, direct client engagements, and systems I have designed and built for my own operations.
