01 / what i do

The full stack of an AI product.

01

RAG and agentic systems

Retrieval pipelines and multi-step agent workflows that hold up in production, built with LangChain, LangGraph, FastAPI, vLLM, and Qdrant.

02

AI-native frontends

Streaming interfaces that make model output feel instant, from SignalR token streams to optimistic UI, in React, Next.js, and TypeScript.

03

NLP for low-resource languages

Custom hate-speech and misinformation detection models for Amharic and other Ethiopian languages, a space where off-the-shelf models fail.

02 / the pipeline

How an AI feature ships.

The same path runs under everything I build, from TravelColombia.ai to the logistics RAG engine at Adilas Tech. Data in, grounded answer out, streamed into an interface that keeps up.

05 / career

Where I have been.

  1. AdilasTech

    Nov 2025 - Present

    Senior Software Engineer, AI and Frontend Lead

    Onsite, Addis Ababa · US company, Virginia HQ

    Took a logistics platform from no AI capability to a live streaming assistant, and set the reference architecture the engineering team now builds against.

    ai · ml

    • Built the company's first production LLM inference stack: a FastAPI and vLLM service handling concurrent token generation, serving several hundred concurrent requests at peak.

    frontend

    • Architected the real-time streaming interface: a React client consuming the inference API over SignalR, with token-by-token rendering, scroll anchoring, request cancellation, and recovery from partial or failed streams.

    both

    • Established the concurrency, backpressure, and error-recovery patterns now standard across every AI feature in the product.
  2. SkyHighCloud

    Nov 2024 - Jul 2025

    Senior Software Engineer

    Remote, Coimbatore, India

    Led delivery across 10+ client products collectively supporting 100,000+ monthly sessions.

    ai · ml

    • Led LLM integration across 10+ client products, delivering structured extraction, summarization, and conversational agents on shared internal patterns that cut AI integration time on new projects from weeks to days.

    frontend

    • Led frontend development for 10+ client products in Next.js and React, spanning data-heavy dashboards, multi-tenant platforms, and AI-driven tools.

    both

    • Owned deployment on AWS with Docker and GitHub Actions CI/CD, automating Jest and Cypress runs, type checks, linting, and preview deployments across a distributed team.
  3. Adotsense

    May 2021 - Nov 2024

    Machine Learning Engineer and R&D Lead

    Remote, Addis Ababa

    Led R&D for hate-speech and misinformation detection in languages with no usable pretrained baselines.

    ai · ml

    • Led R&D for hate-speech and misinformation detection in Amharic, Afaan Oromo, and Tigrinya, owning the full lifecycle from dataset construction through production deployment.

    frontend

    • Built and owned the complete React frontend for the internal ML analysis platform, giving researchers interactive visualization of model outputs over large, noisy datasets with D3.js and Recharts.

    both

    • Used engagement analytics and A/B testing to direct training data selection and public-facing component decisions, contributing to a 170% increase in traffic over six months.
  4. Maed Technologies

    Dec 2019 - May 2021

    Software Developer

    Remote, Debre Birhan

    Shipped two products for a university campus, both grounded in direct user research.

    frontend

    • Launched a cross-platform Flutter app for campus navigation and real-time announcements, reaching 2,000+ active users in its first year.

    both

    • Conducted requirements research with 250 university students and translated the findings into the prioritized specification and information architecture for both products.
