WhatI do

I'm most energized by projects where I can dig into complex problems, work with smart people, and ship software that genuinely improves someone's day.

How I
work

Discover

First, I get familiar with the problem, the people, and the constraints around it.

Architect

I turn requirements into a clear system design, data model, and set of priorities.

Build

Then I build, review, and refine until the code is solid, fast, and readable.

Ship

Finally, I deploy to production, watch stability, and keep improving after release.

FAQ

  1. Question

    Yes. 5+ Flutter apps shipped so far, including delivery apps with real-time Socket.io notifications, and React Native work today.

  3. Question

    User

    What does working with AWS look like?

    Lambda and SQS for synchronous and asynchronous processes, S3 and Rekognition for media and face comparison, and Kinesis for streams, all built to scale and stay cost-efficient.

  4. Question

    User

    Can Semere lead a team?

    Yes. Tech Lead at Byond, lead of a five-developer team on the IMIS project for the Institute of Foreign Affairs, and co-founder and CTO of Bebe Organization.
