# Dzmitry Zubakin

> Product Engineer. Munich, Germany.

I build web and mobile products at Tools for Humanity, from the interface to the systems behind it.

I also build LLM applications and agentic systems, with Claude Code and Codex as part of my development workflow.

## Experience

### Tools for Humanity
Senior Software Engineer | Oct 2023 — now

I build user-facing features for the Operator and Enterprise apps, including device management, onboarding and account workflows.

Key-page LCP: approximately 5.5s → 2.1s.

- Device management: I build the flows operators use to order and set up devices. I work with the Orb Software team on the app side of features such as Network Center.
- Enterprise workflows: Onboarding, account linking and user-management interfaces that reflect each person’s role. I also work on Zoom integration, audit logs and the notification delivery system.
- Orb on Demand: A feature for booking a verification visit. I built the frontend and serverless backend on AWS, including booking and calls between users and operators without sharing personal phone numbers.
- Application architecture: I work with backend-for-frontend (BFF) APIs shaped around the client’s needs, and server-driven UI (SDUI), where the backend defines how screens are composed.
- In production: Real-user monitoring helped me find and fix loading bottlenecks. I added Datadog logging for Next.js services and PostHog analytics, and investigate incidents as part of the on-call rotation.
- Since October 2023: I started on these products through Ottofeller in October 2023 and joined Tools for Humanity directly in October 2024.
