Founding AI Engineer · Head of Engineering · Founder at Friendly

I design and ship production AI systems, data-heavy platforms, and product-grade automation for B2B companies.

I am most useful when a team needs to turn manual operations into software, move an AI prototype into production, or modernize a critical platform without growing engineering headcount proportionally.

Based in Brasília, Brazil — working remotely with international teams.

Building something around AI, automation, or platform engineering?
I take on a small number of consulting, advisory, and product-engineering engagements. Tell me what you are building or connect on LinkedIn.

• Helped scale a B2B company from approximately 5 customers at join to 53 cumulative customers served, while operating as its sole engineer and technical lead.
• Reduced a core operational workflow by 21×, from approximately 11.7 hours to 33 minutes.
• Built an AI data workflow that has processed 293.6K rows across 96 completed runs, produced 150.6K usable leads, and saved 55.1 hours of manual cleanup.
• Architected a 12-agent AI data-quality system scanning 2.8M+ records, reducing tracked issues by 96% and improving the internal database-health score from 78% to 95%+.
• Led cloud and infrastructure modernization that reduced operating costs by 40%.
• Built systems that enabled 5× operational growth and supported 900+ customer meetings in 2025.

I work with early-stage B2B companies and data-heavy operational teams that need senior technical ownership without immediately building a full engineering organization.

For teams with an AI prototype or manual workflow that needs to become reliable production software.

Typical work includes:

• Agent architecture and workflow decomposition
• Structured outputs, evals, observability, and prompt versioning
• Deterministic safeguards and human-in-the-loop review
• Reliability, retry, and failure-recovery design
• Data pipelines, enrichment, classification, and entity resolution

For companies running critical operations through spreadsheets, scripts, and disconnected tools.

I help turn those workflows into:

• Internal platforms and customer-facing product capabilities
• Automated and observable data pipelines
• Provider integrations, migrations, webhooks, queues, and backfills
• Reviewable workflows that preserve operator control

For founders who need someone to own both technical strategy and execution.

I can help with:

• Architecture and technical roadmap
• Product and infrastructure decisions
• Cloud cost and reliability improvements
• Engineering standards, security, and delivery
• Hands-on implementation of the highest-risk systems

Leading BuyerSight's transformation from spreadsheet-heavy outbound operations into an AI-powered B2B SaaS platform.

I own product and technical execution across architecture, Rails, Python, Go, Next.js, PostgreSQL, Google Cloud, DevOps, security, QA, and production AI systems.

Recent work includes:

• Production AI-agent workflows using OpenAI, RAG, evals, structured outputs, human approval, and LangSmith observability
• A production list-hygiene workflow that has processed 293.6K rows across 96 completed runs, producing 150.6K usable leads and 94 detailed reports
• Hybrid company-resolution automation for a backlog of approximately 62K unlinked contacts
• A multi-provider Unified Inbox with server-side categorization and reply workflows
• An end-to-end Smartlead-to-Email Bison provider migration

Building privacy-first, local-first products for personal knowledge, time, and mobile productivity.

Current products include:

• Notely — a local-first knowledge workspace with encrypted SQLite libraries, on-device semantic search, OCR, transcription, graph navigation, tasks, files, and Canvas
• Timely — a private macOS calendar combining events, Apple Reminders, local meeting notes, and keyboard-first workflows
• Barely — a privacy-first Android launcher built with Kotlin and Jetpack Compose

Across Friendly, I own product strategy, design, application engineering, security, release infrastructure, and cross-platform distribution.

A sanitized breakdown of how I combine deterministic checks, retrieval, specialized agents, structured outputs, observability, confidence-based routing, and human review in production workflows.

How I helped transform spreadsheet-heavy operations into a multi-service product platform that supported growth from approximately 5 customers at join to 53 cumulative customers served.

A minimal, wallpaper-first Android launcher built with Kotlin and Jetpack Compose.

Focus: Android platform APIs, local fuzzy search, widgets, work and private profiles, foldables, tablets, DeX, accessibility, localization, release signing, CI, and performance benchmarking.

A cross-platform Go CLI for tagging, navigating, and operating across distributed project directories.

Focus: Go, SQLite, CLI design, local-first developer tooling, parallel operations, import/export, shell integration, automated testing, and releases.

Built a wildfire prevention and reporting product using crowdsourcing and NASA data concepts.

AI systems: OpenAI, Agents SDK, structured outputs, RAG, evals, LangSmith, human-in-the-loop workflows

Backend: Ruby, Rails, Python, Go, TypeScript, FastAPI, PostgreSQL, Redis

Product: Next.js, React, Electron, Kotlin, Jetpack Compose

Infrastructure: Google Cloud, Cloud Run, Cloud SQL, Terraform, Docker, Cloudflare Workers, Cloudflare R2

• You have a valuable manual workflow that needs to become software
• Your AI prototype works in demos but is not reliable in production
• Your platform is slowing down product or operational growth
• You need senior technical ownership before hiring a full engineering team
• You need someone who can own strategy and still ship the implementation

I focus on production systems and measurable operational outcomes, not one-off AI demos.
