About

I’m a software engineer in Sofia with 10+ years of experience. Most of my work is web applications in TypeScript, React and Node.js, though I’ve worked on every layer of the stack, including databases and infrastructure.

I like teams that ship fast and care whether the code is useful to the people using it. Good architecture and clean code matter to me. So does working well with other people: being clear, and making pragmatic decisions that keep the team moving.

I use Neovim btw.

Experience

TypeScript Go PHP React NestJS Nx Material UI Node.js Auth0 Ory OAuth 2.0 OIDC SSO AWS Docker REST PostgreSQLMCPVitePlaywrightWebSockets

Led Dashboard MCP, a centralized Model Context Protocol server that lets cPanel and Plesk customers deploy and manage their sites from Claude and other LLM clients over OAuth 2.1 with PKCE, instead of over SSH.
Designed the authorization and auditing model behind it around OAuth scopes and short-lived, least-privilege credentials.
Owned the migration of Plesk 360 accounts to the unified WebPros Account, including account linking and MFA re-enrollment.
Added federated identity to the platform: Google, Facebook, cPanelID and Microsoft Entra OIDC, including session invalidation when the user logs out on the provider side.
Migrated the product from a plain Express app to an Nx monorepo on NestJS, and kept modernizing it afterwards: Webpack to Vite, Cypress to Playwright, MUI v7 on a shared theme published as a private npm package.
Shipped features across several brands from a single codebase (WebPros Dashboard, Platform 360, WP Guardian, Partners), including server inventory, website management, adaptive layouts and live updates over WebSockets.
Built WP Guardian’s security features: virtual patching for WordPress sites, automated update policies, scheduled security checks, and branded sign-up and login flows.
Developed cross-language extensions in PHP and Go, including Go agents for secure communication with customer servers.
Instrumented the platform for product analytics (Mixpanel, Amplitude, HubSpot, Google Analytics) and implemented the GDPR and consent requirements around sign-up and marketing flows.
Onboarded external teams, mentored engineers, and wrote the architecture documents the rest of the organization works from.

Go PHP TypeScript React Node.js Docker REST Microservices Nightwatch PostgreSQL LinuxRBACCypressJest

Led the architecture of Solus IO, WebPros virtual machine management platform, from early alpha through to its production releases.
Rebuilt VM provisioning on an asynchronous task and queue system with retries, health checks and compute-resource balancing strategies, replacing a synchronous flow that did not scale.
Designed the multi-tenant model: projects and project members, RBAC roles and permissions, per-user limit groups, and zones grouping compute resources.
Delivered VM capabilities end to end, including snapshots, resize with disk preservation, rescue mode, NFS, reverse DNS, cloud-init presets, traffic isolation, bandwidth limits and SSH key management.
Built the Applications subsystem on Twig templates with JSON Schema-driven dynamic forms, so new one-click deployments could ship without code changes.
Integrated billing and licensing: a WHMCS provisioning module and API endpoints, a generic integration for other billing systems, and a move from XML licenses to JWT tokens.
Split the frontend into isolated admin and client areas, rebuilt it on React with a shared component library, and added white-label branding for colors, logo and product name.
Wrote core services in Go and delivered backend and frontend in PHP 7 and 8, TypeScript and React.
Set up the quality tooling: Cypress and Jest suites, Nightwatch automation, SonarQube, lint pre-commit hooks, staging deploy pipelines, and the PHP 7.4 to 8 upgrade.
Acted as Technical Lead, owning architecture decisions, task decomposition and coordination across backend, frontend and QA.
