--- title: "About — Symonov, a two-engineer dev team" description: "Two engineers, one team. Serhii — backend / full-stack, WordPress plugins. Dmytro — senior frontend / full-stack. Work with us together or individually." url: https://symonov.com/about/ --- # Two engineers. One team. Symonov is two brothers working as one team, shipping production code together since 2017. Work is split by ownership — Serhii owns the backend and WordPress, Dmytro owns the frontend — so each part has one engineer accountable for it. No project managers between you and the people writing the code. Work with us together on a project, or with either of us individually — part-time or long-term. ## serhii symonov — backend / full-stack engineer ![Serhii Symonov — backend / full-stack engineer](https://symonov.com/_astro/serhii-low-poly.CyDM_iHb_Z2nRR3.webp) Backend / full-stack engineer with a long focus on **WordPress plugin development** and **Laravel platforms**.

CI is part of the codebase, not someone else's job. - no telemetry, no admin nag screens, no upsells in plugins we maintain. - direct communication. you talk to the people writing the code. ## contacts — how to reach us - email: [hello@symonov.com](mailto:hello@symonov.com) (team · preferred) - serhii symonov: [serhii@symonov.com](mailto:serhii@symonov.com) - dmytro symonov: [dmytro@symonov.com](mailto:dmytro@symonov.com) - telegram: [@symonov\_bot](https://t.me/symonov_bot) - github: [symonovserhii](https://github.com/symonovserhii) (serhii symonov) - github: [Kassaila](https://github.com/Kassaila) (dmytro symonov) - wp.org: [profiles.wordpress.org/simmotorlp](https://profiles.wordpress.org/simmotorlp/) (serhii symonov) - npm: [npmjs.com/~kassaila](https://www.npmjs.com/~kassaila) (dmytro symonov) → [full contact page](https://symonov.com/contact/)
