# Symonov

> Two engineers, one team (Serhii & Dmytro Symonov). WordPress plugins and Laravel
> backends, Vue + TypeScript frontend, Telegram bots and Mini Apps. Shipping production
> code together since 2017. Work with us together or individually.

Symonov is not an agency or a studio — it is two brothers working as one team, with work
split by ownership. Serhii Symonov is a backend / full-stack engineer (PHP, Laravel,
WordPress plugins published on wp.org), running fintech web platforms (crowdfunding /
investment) since 2022. Dmytro Symonov is a senior frontend / full-stack engineer (Vue,
Nuxt, TypeScript, Node.js / Fastify), in fintech and e-commerce since 2019 and leading
frontend since 2022, with open-source packages on npm. Together we build full-stack
platforms, Telegram bots and Mini Apps.

Collaboration: hire us together for a whole project, or either of us individually —
per project, part-time, or long-term.
