AI Engineer / Full-Stack Developer

I build modern software that blends intelligence, speed, and seamless user experience.

About

I'm a frontend engineer who cares about accessible, pixel-perfect experiences on the web. Day to day I lean on TypeScript and JavaScript across React and Next.js, with Node.js when the UI needs a solid API surface; I'm also fluent in Python for tooling and services, comfortable with C++, SQL, and Bash when work sits closer to systems or data, and I reach for PostgreSQL, MongoDB, Redis, Docker, Tailwind CSS, Vue, Express, and GitHub Actions when the problem calls for them.

Right now I'm a founding engineer at Alactive, leading development of a multi-agent system with models tuned for specific tasks. I integrate the product with WhatsApp, Outlook and Gmail, web clients, and multiple property-management systems using public APIs and targeted reverse engineering where integrations aren't documented. I cut end-to-end response time by about twenty-six percent with a router that selects models based on query complexity, and I build internal tools to monitor and operate the platform.

Earlier roles rounded me out across the stack: I shipped Vue and Express features at GO PLATFORM after researching competitors and reverse-engineering closed-source tools to map architecture; at Datafinity I scaled Supabase-backed Postgres with indexing and caching while locking down TLS, hardened APIs, and access control; at Brighter Generation I led a team of four on a chronic-care monitoring product deployed across hospitals, pairing React, Node, Express, and MongoDB with IoT hardware collaborators.

I'm pursuing a BS in Software Engineering at Addis Ababa Science and Technology University (ongoing since September 2023), with coursework spanning object-oriented programming, data structures and algorithms, web and mobile development, requirements and systems design, operating systems, agile delivery, introductory ML, and security. On the side I keep shipping projects like browser extensions and an applicant-tracking workspace—always chasing interfaces that feel great and backends that stay dependable.

Projects

  • Tabs

    A cross-browser side-panel extension for saving and organizing the pages you want to keep without leaving them open. It lets you capture the current tab or an entire session, group and search saved links, and return to them later from a clean, lightweight workspace. Available in the Chrome Web Store and Firefox Add-ons.
