Bekretsion Seyoum · backend software engineer · Addis Ababa, Ethiopia
Real-time backends, multi-tenant APIs, and voice AI that picks up the phone.
Five things I built, below — open a card to see the build and its walkthrough side by side.
Background
A few things worth mentioning.
0
Double-bookings
A buffer guard and a shared conflict check sit in front of every booking path, so two requests for the same slot can never both win.
6
Platforms, one connector shape
Planday, Fiken, Stripe, Vipps — different APIs, same connector pattern underneath, so the sixth integration took a fraction of the first.
2 tiers
Cloned voice, shipped
Two-tier voice cloning went from idea to a metered, resellable feature — credits tracked per minute, catalog leak-filtered per account.
Finalist
ALX Ethiopia × Kuriftu Hospitality Hackathon, 2026
Hello, an AI voice receptionist for hotels, made the national final: ElevenLabs or Vapi behind one interface, Stripe minute top-ups, and a post-call engine that fires Slack, Outlook and CRM actions.
95+
Languages, Amharic included
Hello answers in 95+ languages through ElevenLabs multilingual models — including Amharic, Afaan Oromo and Tigrinya, which most voice products still skip.
SSGI
Forecasting geomagnetic storms
Internship at Ethiopia’s Space Science and Geospatial Institute: a CNN-LSTM that predicts the Dst index from solar-wind data. The second version beat the persistence baseline at every horizon — after finding that the first only looked like it never learned because of an early-stopping bug.

Voice AIHello AI
AI voice receptionist platform: assistants, phone numbers, calls captured and billed by the minute. National finalist, ALX × Kuriftu 2026.
Real-timeCollab API
Self-hostable WebSocket backend for collaborative editing: Yjs CRDTs, tenant isolation at the database, Redis scale-out.
AutomationLead Qualification
Inbound-lead pipeline on n8n: LLM scoring, atomic dedupe, and routing to HubSpot, Slack and Gmail within seconds.
Document AIDocument Invoice Processing
OCR and LLM extraction for invoices — clean, scanned, skewed, handwritten — validated before anything posts.
Media pipelineChannel Builder
Scripts in, narrated and cut videos out: TTS, Whisper alignment, ffmpeg assembly, and a clip-finder that trims the dead air.
