Samuel Miranda Martínez | Senior Software Engineer

Software Engineer with 10+ years in React, TypeScript, and React Native. I maintain my own infrastructure with Docker and Go agents that automate everything from backups to a science content pipeline producing ~4 videos/day without manual intervention.

• 🔭 Currently building B2B and B2C platforms at Apply Digital
• 🧪 Cocreator of Ciencia a Mordiscos — automated science content pipeline for YouTube & TikTok, with WhatsApp audio newsletters and generative music as sibling systems
• 🖥️ Running my own infrastructure with Docker, Traefik, CrowdSec and ~40 Go binaries that operate content, backups, monitoring, auditing, and security
• 🤖 Built an LLM gateway and multi-agent editorial pipeline in Go — priority queue, reviewers with real veto, human-in-the-loop via Linear, and evals checked against real audience
• 🚀 Contentful Certified Professional (2024) · Claude Code in Action, Building with the Claude API & MCP (Anthropic, 2026)

SaaS for TikTok and Pinterest automation. REST API with secure OAuth, n8n/Zapier/Make integration, and monitoring dashboard. Serverless on Cloudflare.

Cloudflare Functions D1 Database TikTok API Pinterest API OAuth 2.0 Astro

Autonomous editorial pipeline turning scientific papers into ~4 daily videos for YouTube and TikTok. Four parallel LLM reviewers, two with real veto (they fetch sources and verify citations verbatim); human approval from Linear; LLM scores evaluated against real audience and dropped from the gates when they did not correlate.

Seed-based 3-hour sessions with direct DSP (no MIDI or soundfonts), act-based narrative arc, and per-genre generative visuals. Quality measured with CLAP, FAD, and fatigue proxies plus logged blind listening; gates run in CI. Episodes published on YouTube.

Python numpy/scipy PyTorch CLAP Demucs FFmpeg YouTube API

Open-source Android app that blocks spam calls with zero internet connection. Two blocking modes, urgency bypass, schedules, whitelist, Jetpack Glance widget, exportable history, and privacy dashboard. Zero data sent to the cloud.

Server running five automated editorial systems on a ~70k LOC Go monorepo with ~40 binaries and ~35 systemd timers. ~20 containers behind Traefik (HTTP/3, CrowdSec, HSTS), CI/CD on a self-hosted runner with SAST, CVE scan, and E2E smoke tests, ~40 monitoring checks with severity-routed alerts, weekly-verified Borg backups, and continuous auditing of code, dependencies, and Cloudflare config against a baseline.

~40 Go binaries that replaced ~40 bash/Node.js scripts to operate the server: health checks, dependency updates, code and Cloudflare auditing. Circuit breakers, per-file mutex, retry policies, and severity-routed alerts (Gotify push / Linear issue).

Go SQLite systemd Docker Gotify Linear API Cloudflare API Claude API

Go proxy with an Anthropic SDK-compatible /v1/messages endpoint: 4-level priority queue, per-service API keys, SSE streaming, rate limiting, and token/cost accounting per service and model. A Runner abstraction lets agents switch between Claude CLI and the Go SDK (prompt caching, Batch API) without changing the call site.

Go SQLite SSE Anthropic API Anthropic SDK Docker

Picks up Linear issues labeled dev-agent and runs them through 6 phases (Planner → Builder → Auditor → Fixer → Re-auditor → Tester) driven by Linear labels. Opens GitHub draft PRs with human gates at plan and integration; the Auditor waits for CI and classifies findings by severity.
