Kaleab GulilatI design and ship products end to end — from application architecture and backend systems to polished interfaces, real-time experiences, and AI agents.
Recently, I’ve been building a production multi-tenant AI classroom combining live voice, multi-agent orchestration, RAG, assessments, and real-time student interaction. I use Mastra for more structured, observable, and maintainable agent systems.

Production products and technical systems I’ve helped architect, build, and ship across AI, real-time applications, SaaS, commerce, and business software.
Sole Full-Stack Engineer
Architected and built a production, multi-tenant classroom platform in which AI agents conduct live lessons and interact with students in real time.
The platform combines multi-agent orchestration, WebRTC voice interaction, RAG over educational materials, dynamic assessments, classroom engagement tools, personalized student insights, and organization-level authorization.

Lead Frontend Engineer
Led frontend implementation and contributed to the architecture of a PostgreSQL-backed insurance-management application built with Ruby on Rails.
Worked across real-time updates, document generation, external API integrations, role-based authorization, and complex business workflows.
Full-Stack Engineer
Built an automated content pipeline processing 5,000+ articles per day from multiple sources.
Designed Puppeteer scraping and scheduled ingestion supporting as many as 15 concurrent sources, followed by processing, categorization, and AI-assisted summarization and aggregation.

Primary Frontend & Backend Engineer
Built the primary frontend and backend of a Rails prototype where users upload energy-plan documents and receive AI-assisted comparisons and recommendations.
Worked alongside an AI engineer on agent integration and provisioned production infrastructure using Kamal on a Hetzner VPS.
Sole Full-Stack Engineer
Own the architecture and development of a production multi-tenant AI classroom. Use Mastra for agent orchestration, with specialized teacher and supervisor agents, tools, and workflows. Designed the agent architecture, real-time classroom interactions, WebRTC voice communication, RAG workflows, background assessment generation, analytics, and organization-level authorization. Responsible for frontend, backend, data architecture, AI integration, infrastructure decisions, and production delivery.
Full-Stack Engineer
Nov 2024–Present
Work with product teams on production applications across AI, SaaS, commerce, and CMS-driven products. Recent work includes EasyBoatDeals with Next.js, Payload CMS, search, authentication, SSR, and Stripe, and HeyMilo’s AI interview product with Next.js, Tailwind CSS, and VapiAI.
Full-Stack Engineer
Jun 2023–Aug 2024
Delivered web applications and CMS-driven products using Next.js, Payload CMS, Craft CMS, Tailwind CSS, and Ruby on Rails. Led frontend delivery while contributing to backend architecture, real-time systems, API integrations, document generation, AI prototypes, deployment infrastructure, and high-volume content ingestion.
Full-Stack Engineer
Jun 2022–Oct 2022
Built an issue-tracking application using C# and React and contributed across planning, technical solution design, implementation, and testing for client projects.
I work across the entire product stack rather than limiting myself to a single layer.
I’m a full-stack and AI engineer based in Addis Ababa, Ethiopia.
I enjoy working on products where frontend, backend, infrastructure, AI, and product decisions intersect rather than treating them as isolated disciplines.
My experience spans AI products, real-time systems, SaaS platforms, commerce, CMS-driven applications, internal business tools, data pipelines, and early-stage prototypes.
More recently, I’ve become particularly interested in the architecture behind production AI agents: how agents use tools, how deterministic workflows and model reasoning should interact, how context and retrieval are managed, and how complex agent behavior can be observed and evaluated.
I use Mastra as a core part of the architecture for new agentic products and the continued evolution of my existing AI systems.
Outside software, I spend a lot of time playing chess, reading, learning, and training.

I’m open to full-stack and AI engineering opportunities, particularly around agentic AI, SaaS, real-time systems, and technically challenging web products.
If you’re building something where I could help with architecture, implementation, or taking a product from idea to production, get in touch.
