Profile

Current engineering scope.

My work often crosses several parts of a system: permissions, configurable data, state transitions, integrations, performance, deployment and recovery.

At CDM I design and build Cerps, a configurable operations platform with dynamic data structures, field-level history, ABAC, triggers, chats, reports, realtime updates and 1C integration. Earlier work includes security monitoring interfaces and an applied software lab.

I write user-facing React code and follow production issues through the API, database, queue, proxy and server when needed.

What I do

Frontend, backend and infrastructure.

Business systems

Configurable entities, audit trails, access rules, workflow fields, triggers, reports and operational dashboards.

Backend and data

Node.js and NestJS services, typed APIs, PostgreSQL, Redis, query DSLs, integrations and defensive validation.

Product interfaces

React applications, realtime event views, routing, state management, caching, localization and resilient error handling.

Production ownership

Linux servers, containers, reverse proxies, SSL, monitoring, backups, restore checks and incident investigation.

An independent product I run.

CheckFastWeb diagnostics

Independent product - 2026 - present

CheckFast is a live set of web diagnostics I built for developers and site owners. It combines an all-in-one site check with focused tools for SSL, DNS, email deliverability, redirects, SEO, response headers and more.

I built the Next.js and React application, checker packages, public API paths and the production deployment. The engineering focus is safe outbound networking, graceful degradation and consistent results between the UI and API.

Product: 40+ focused web and infrastructure checks
Architecture: Next.js monorepo with shared checker packages
Network safety: Redirect and DNS rebinding defenses for outbound requests
Operations: Docker deployment, health endpoints and metrics
