Samuel Gadiel

Mobile Tech Lead & Senior Flutter Engineer based in Brazil, building AI-augmented engineering workflows.

I build cross-platform mobile apps and the infrastructure to ship them at scale. My most defining work: a white-label B2B platform with 100+ apps published on Google Play and the App Store, automated end-to-end with a CI/CD pipeline I built from scratch — Fastlane + Jenkins running on a self-configured macOS virtualized inside Docker.

More recently, I architected a multi-agent Spec-Driven Development (SDD) methodology on top of Claude Code — Product Owner, Tech Lead, Senior Developer and QA agent personas, custom MCP servers, and traceable specs — now adopted team-wide across the mobile squad.

What I work with

  • Mobile: Flutter · Dart · Clean Architecture · BLoC · DDD · TDD
  • AI Engineering: Claude Code · Multi-agent orchestration (SDD) · Model Context Protocol (MCP) server development · LLM gateways · Agent memory
  • DevOps: Fastlane · Jenkins · GitHub Actions · Docker · Bash
  • Cloud: Terraform · AWS (App Config · EC2 · S3 · Route 53 · ECS · CloudWatch)
  • Observability: Grafana · Loki · Prometheus · Tempo
  • Frontend: React · TypeScript · Tailwind CSS · shadcn/ui

AI & automation

  • Multi-agent SDD pipeline (Claude Code): 4 specialized agent personas enforcing strict role separation from Jira refinement to QA sign-off, with 76+ traceable production specs and zero unreviewed AI commits.
  • Custom Model Context Protocol (MCP) servers (Node.js), including an OpenAPI/Swagger wrapper with a custom OAuth-style auth provider and automatic token refresh, alongside Jira, Figma and Dart MCP integrations.
  • Hermes Agent — self-hosted, always-on personal AI assistant (persistent cross-session memory, self-improving skills) running 24/7 on Oracle Cloud, with a Tailscale reverse-proxy tunnel to a home Raspberry Pi for residential-IP web access and a Telegram bot front-end.
  • OmniRoute — multi-provider LLM gateway/proxy with pooling and failover.

Highlighted projects

  • mason_cat — Mason brick for Clean Architecture scaffolding in Flutter. Reduces module setup from hours to seconds. Published on MasonHub.
  • nand2tetris — Full implementation of a computer from NAND gates up to an assembly language.
  • sort_animation — Sorting algorithm visualizer in Flutter.
