Sergiu Toderascu

Software engineer
learning by breaking things.

I build developer tooling and AI-powered engineering workflows for teams shipping across mobile, web, and backend. Currently leading Busymate DevTools — an AI-first platform that captures, inspects, mocks, and replays HTTPS traffic from every device into one live dashboard — and Busymate AI — a white-label AI assistant and live-agent inbox for business websites and messaging channels.

About

I'm a software engineer focused on developer tooling and AI engineering — building the systems that make complex software legible and controllable. The through-line of my work is closing the loop between what a system is doing and what you can observe and change about it: traffic inspection, runtime tooling, and agent-ready integrations.

I lead development of Busymate DevTools, an AI-first platform for capturing, inspecting, mocking, and replaying HTTPS traffic across iPhones, Android, browsers, and device farms — unified in one realtime dashboard, with an AI teammate (BusyBro), a large MCP tool surface, REST/WebSocket APIs, and enterprise-grade security.

I also lead Busymate AI, a white-label AI customer-messaging platform — an assistant plus a live-agent inbox — that any business embeds on its own website and messaging channels under its own name.

Earlier work spans mobile tooling (Capacitor native plugins and SwiftUI components) and web-runtime tooling (debuno — bringing Deno-style module resolution to Bun and Node). I organize this work through the BusyBrothers team and have been publishing open-source software on GitHub since 2011.

Work

Busymate DevTools

busymate.dev ↗

AI-first HTTPS traffic capture, inspection, mocking, and replay for development teams debugging across every device — unified in one realtime dashboard.

iOS · Android · browsers · device farms 303-tool MCP server BusyBro AI teammate RBAC · audit · vault
  • Capture everywhere — on-device VPN for iOS, MITM proxy for Android & browsers, zero-install CLI for Chrome, and device farms at scale.
  • Inspect & manipulate — realtime dashboard with filtering, breakpoints, hand-editing, and scripted mocking via a sandboxed JS engine.
  • AI teammate (BusyBro) — persistent memory, integrated directly into debugging workflows.
  • Agent-ready — a 303-tool MCP server for Claude, Cursor, and other agents; REST & WebSocket APIs for programmatic access.
  • Enterprise security — database-enforced RBAC, audit trails, and an encrypted vault.

Busymate AI

busymate.ai ↗

An AI assistant that learns from your website, answers questions, helps customers choose, and hands the hot ones to your team — under your own name, on your own web address, day and night.

Web chat · email · Telegram · SMS AI assistant + live-agent inbox White-label by default
  • Learns your business — trained on your own website content, so answers stay accurate and on-brand.
  • Live-agent inbox — hands a conversation to a human teammate the moment it needs one.
  • Every channel — web chat widget, email, Telegram, SMS, and more, from one shared brain.
  • White-label — runs under the business's own name and domain, not Busymate's.
