Hanif Carroll
Forward Deployed Engineer
I work directly with clients to understand their workflows, define a practical scope, and build the software that supports their work.
My experience spans operations tools, integrations, production AI applications, and improving existing products.
Available for fully remote roles and contracts with AI implementation agencies.

Built a searchable parts catalog, then translated a returning client’s sales, payment, and dismantling workflows into a specification and role-based prototype.

Worked directly with the founder on AI seller workflows and the account permissions, billing, credits, and recoverable processing behind them.
Palabruno — From product scope to launch and handoff
Collaborated on scope and learner/teacher workflows, then delivered web and mobile applications, subscriptions, payments, and release documentation.
Mucho Hangouts — Stabilizing a live product while delivery continued
Addressed messaging, authentication, and application-state failures in an existing product while providing technical direction and mentoring its developers.

Mucho Hangouts
Fractional CTO · 2025
- Stabilized messaging, notifications, and sign-in in a live product by centralizing authentication and server state and fixing socket connection lifecycles, while feature delivery continued.

Independent products & demos
- Switchboard — Agentic system demo: Built a Python/FastAPI and LangGraph agent that investigates customer-change requests and proposes policy-checked changes for human approval; deployed on AWS using Step Functions, SQS, and DynamoDB.
- Casamo — Independent product: Built an AI product that helps digital nomads find and compare furnished accommodation on Airbnb and Booking.com, evaluating listings against their requirements using photos, amenities, and guest reviews, and highlighting trade-offs and questions to confirm before booking.

About
Hey, I’m Hanif. I’m a forward deployed engineer based in Buenos Aires. I got into programming after Mr. Robot inspired me to learn how to code. I now have 9+ years of experience and work directly with clients on software, integrations, and AI applications.
After working at 8base, Capgemini, and LeagueApps, I now run HC Studio, where I work with founders and product teams to turn ambiguous ideas into useful, reliable software.
My recent client work includes operational discovery and a prototype for Desarmadero La Torre. I also helped Genrupt support its first 200 paying customers and took Palabruno from an early prototype to launch across iOS, Android, and web.
For the past three years, I’ve used coding agents to build software and complete workflows across websites and apps. My experience includes Cursor, Claude Code, Codex, and Pi. I’ve written about using agent-generated diagrams to review Casamo’s workflow.
I’m interested in how businesses organize work and where software can help. I’m currently reading Fundamentals of Business Process Management, Thinking in Systems, and Designing Your Organization to deepen my understanding of processes, systems, and organizational design.
Outside of work, I like to lift weights, experiment with AI, and have merienda in cozy coffee shops.
