Henok Robale

Founder, Go Robale

Architecting scalable, data-driven enterprise web applications and secure AI integrations.

I specialize in bridging the gap between raw backend architecture and executive decision-making. By leveraging modern frameworks and component-driven UI, I transform complex data pipelines, agentic workflows, and network-security logic into premium, high-fidelity user experiences.

Engineering Highlights

  • Engineered and deployed secure internal financial processing and tax-management systems directly into the architecture, eliminating reliance on third-party SaaS dependencies.
  • Upgraded the underlying network infrastructure to seamlessly support multiple ministry service systems under one roof.
  • Executed end-to-end as sole technical founder — architecting the database, API routing, and final frontend UI.

Flagship Build

FellowFlow — Conference Management

Event Logistics Platform

A custom-built registration, logistics, and data-management platform engineered to handle complex user flows and large-scale event data.

Engineering Highlights

  • Designed interactive, high-fidelity dashboards to visualize bulk registrant data and simplify complex administrative workflows.
  • Built scalable logic pipelines to handle heavy backend data hand-offs cleanly, without bottlenecking client-side performance.
  • Architected role-based access and secure data handling to keep large registrant datasets isolated and auditable.

GoRobale Stream-Hub

Multi-Platform Live Streaming Engine

A multi-destination live-streaming engine that broadcasts a single OBS feed to YouTube, Twitch, Facebook, and custom RTMP targets simultaneously, with unified chat aggregation and scheduled stream management.

Next.jsnode-media-serverFFmpeg / RTMPSupabaseFly.ioYouTube Data API

Engineering Highlights

  • Built a real-time Studio Control Room — dual-pane video preview (FLV proxy), stream-health diagnostics, and cross-platform chat aggregation in one dashboard.
  • Engineered an FFmpeg-based RTMP relay that fans out to multiple platforms with 5-second health polling, YouTube broadcast-lifecycle monitoring, and automatic intro-to-live fallback.
  • Deployed a persistent, memory-tuned RTMP service on Fly.io with TCP health checks and database-driven state recovery for reliable, resumable broadcasts.
04

Scripture Unlock

AI-Powered iOS App

A native iOS app (~18.5K LOC) that wakes users with scriptural alarms powered by Gemini-generated trivia — gamified with streaks and achievements, backed by cloud auth and sync.

SwiftUISwiftDataSupabaseGoogle GeminiFastAPI (TTS)Railway

Engineering Highlights

  • Designed a modal-proof alarm experience that can only be dismissed by completing the trivia quiz, with foreground-aware audio recovery.
  • Built an async question-prefetch pipeline that caches trivia offline and triggers background Gemini generation before the cache runs dry — validated against a Bible API before storage.
  • Isolated cloud sync with Keychain-backed auth, silent token refresh, and SwiftData-to-cloud merge on sign-in.
05

Bro Presenter

Bilingual Presentation Suite

A dual-platform Amharic & English lyrics and scripture presentation tool — a native macOS app plus a modern web version — for churches and worship leaders to compose and project content live.

SwiftUINext.jsSupabase Edge FunctionsOpenAI + GeminiTanStack QueryZustand

Engineering Highlights

  • Built a multi-layer live compositor (background, image, text, lower-thirds) with resolution-independent scaling, OBS integration, and a KeymanWeb Amharic phonetic keyboard.
  • Engineered a 5-path lyrics-import pipeline (Word, CSV, JSON, Gemini AI extraction, live artist browser) over a catalogue of 3,500+ songs with atomic cloud saves and versioned backups.
  • Secured all third-party AI keys behind Supabase Edge Functions — zero embedded secrets — with RLS policies and an atomic-persistence session store.
06

Ethiopian Bible API

Multi-Language REST API

A REST API serving the Bible in five languages (Amharic, Oromo, Tigrigna, English KJV & NIV) alongside quiz generation, a structured mezmur catalogue, and study guides — built to scale.

PythonFastAPISQLAlchemy (async)PostgreSQLScrapyDockerRailway

Engineering Highlights

  • Designed a first-class multi-language OpenAPI schema with reference parsing ("John 3:16"), full-text search, and LTR/RTL metadata mapping.
  • Built a 3-tier mezmur catalogue (Artist → Album → Track) with normalized deduplication across two web crawlers and typed verse/chorus JSON lyrics.
  • Engineered async DB operations with ordered routing, IF-NOT-EXISTS safe migrations for multi-worker deploys, and SSL-conditional connection pooling — containerized with Docker.
07

Zimrah Band Website

Worship Ministry Platform

A production website for the Zimrah worship band with full content management, real-time music data, membership authentication, and admin dashboards.

Engineering Highlights

  • Built a pentatonic music-normalization system that transposes every song to a universal playing standard with semitone precision while preserving original key metadata.
  • Unified real-time Song, Album, Event, and Member data through global context providers with typed accessors — keeping 8+ pages in sync without prop-drilling.
  • Layered production security: Supabase RLS, role-based auth (admin/editor/member/viewer), CRUD activity logging, and hardened security headers.
The Go Robale Advantage

Boutique Customization meets Enterprise Polish

Many enterprise platforms suffer from a massive disconnect between backend engineering and frontend presentation. A powerful backend engine loses its value if the resulting data cannot be easily digested by end-users and stakeholders.

I focus on Boutique Customization and Enterprise Polish. Whether it is mapping complex vulnerability matrices, routing massive API payloads, or securing MCP servers, I build the interactive architecture that makes your underlying technology undeniable.
