Salesforce Developer · Belo Horizonte, BR

I build Salesforce systems that talk to other systems — securely.

Apex, LWC, integrations, and the architecture decisions that hold them together.

About

I've worked with Salesforce for five years. Apex, LWC, Flows, REST integrations, plus the permission models and OWD configuration that make any of it safe to deploy. Right now I'm at Loovi, redesigning permission architecture and writing the Apex REST endpoints that handle our SAP traffic. In 2024 I took eight months off Salesforce to join EY's IT audit team. SOX compliance, controls testing, basically reviewing software from the other side of the table. Useful experience. I came back to development knowing more than I left with.

I also build things outside work. BitterSuite is a globe-based radio aggregator written in Next.js and Supabase, somewhere between Radio Garden and old Mac OS aesthetics. There's a few Notion widgets running on Vercel, and a Discord bot that pulls answers from a Markdown file using the Claude API. These are personal projects, not products. They run, and they solve problems I actually have.

Experience

Oct 2025 — Now

Loovi · Salesforce Developer

  • Redesigned the case object's permission architecture: moved from profile sprawl to a least-privilege model with private OWD, a thin base profile, and modular permission sets. Configured ownership-based sharing rules to grant the read/write access that private orgs make tricky.
  • Built custom Apex REST endpoints (@HttpPost) to ingest data from an external portal. Handles complex JSON deserialization and creates cases plus satellite records in one transaction, keeping relational integrity and atomicity.
  • Designed Record-Triggered Flows for SLA management, integrated with Apex actions for the heavier business logic. Built LWCs embedded in Screen Flows (progress indicators) to guide multi-step user flows.

LWC in a third-party collections portal hit governor limits on load and had a JavaScript syntax error. Fixed with async fetching and a one-line code correction.

LWC Experience Cloud Governor Limits

Collections Portal: Data Audit (in progress)

Audit triggered by a field bug. Found SOQL queries inside loops and a sharing model that hid most of the data agents needed. Fixed both.

Personal Projects

Featured Project

BitterSuite

A global radio explorer built around a 3D WebGL globe. Click anywhere on Earth, tune into a local station, and hear what's playing. The navigation takes cues from Radio Garden; the visual language comes from Poolsuite — retro computer aesthetics, monospaced type, draggable modal windows.

  • 3D globe navigation with Fly-To camera animations based on text input or GPS coordinates
  • Geospatial clustering within a 55km radius to keep WebGL rendering manageable in dense markets
  • Audio engine hardened against CORS errors and Chrome's AbortError on rapid stream switching
  • Random intercept: jumps to a working station anywhere in the world
