About

Engineering products that stay understandable as they grow.

I build and deploy web applications across the interface, backend, and data layer. My work is grounded in problem solving, clear structure, and the practical details that make software easier to use and maintain.

Alongside development, I teach programming through the @ethiopandatech and @tntethiopia YouTube channels. Teaching has strengthened how I explain decisions, collaborate, and break difficult problems into manageable steps.

Build products that feel good to use, scale reliably, and remain enjoyable to maintain.

BE

Backend-aware full stack

I connect interface decisions to APIs, data models, authentication, and the systems that keep a product dependable.

PX

Performance-minded

I treat loading speed, responsive interaction, and maintainable delivery as part of the product experience.

CO

Collaborative delivery

I work through requirements, communicate progress, and turn feedback into focused implementation steps.

TE

Teaching reinforces craft

Teaching programming helps me explain technical ideas clearly and strengthen the fundamentals behind my work.

Selected work

Products explained through the problems and decisions behind them.

How I work

Clear decisions, visible progress, and a release that can keep growing.

A lightweight process keeps the work collaborative without turning delivery into ceremony.

  1. Phase 01

    Discover and define

    Clarify the audience, business goal, constraints, content, and the smallest useful version of the product before choosing implementation details.

    Output
    Scope, priorities, and technical direction

  2. Phase 02

    Build and communicate

    Develop in reviewable slices, keep the system understandable, and share progress early enough for feedback to improve the result.

    Output
    Working increments and visible progress

  3. Phase 03

    Validate and launch

    Test the important journeys, accessibility, responsiveness, and production behavior, then ship with a clear path for iteration.

    Output
    Verified release and maintainable handoff
