Owned cross-cutting frontend initiatives on a Next.js marketplace, taking platform-wide changes — localization, analytics instrumentation, and performance — from scope to production across a shared, fast-moving codebase. Acted as the team's reference point for i18n and Amplitude questions.

• Applied performance optimizations to a production codebase with measurable impact — Lighthouse score on main page improved from 32 to 68
• Localized the platform into 5 languages, with an AI translation pipeline for new i18n keys
• Integrated Amplitude (events, session recording), maintained reliability after team changes caused regressions and acted as go-to for instrumentation questions
• Migrated the platform from Next.js 14 to 16, unblocking adoption of newer framework capabilities

Acted as technical lead for an early-stage booking startup, translating founder requirements into specifications, architecture, and a delivery plan for a four-person team (two junior developers and a QA), then drove the day-to-day implementation and architecture calls.

• Architected a full-stack booking platform from requirements, including database design, system architecture, and security implementation
• Built backend services with NestJS and TypeScript; set up PostgreSQL (RDS) as the primary data store with full schema ownership
• Led technical decision-making and coordinated with the development team on implementation
• Designed and deployed AWS infrastructure with CI/CD pipelines (Fargate, RDS, load balancing)

Delivered features and rescued legacy code across 12 client projects at an outsourcing agency, switching between Vue, React, Express, Nest, and Laravel stacks depending on each engagement. Work ranged from greenfield features to untangling and migrating inherited codebases under delivery pressure.

• Refactored a 6,000-user social platform from Vue Options API to Composition API, improved Lighthouse score from 60 to 90
• Implemented AI-powered real estate research using OpenRouter as a unified provider gateway, replacing direct per-provider API calls
• Restored a production React codebase from source maps and migrated it from Webpack to Vite, achieving a 4x build speed improvement
• Designed a dashboard aggregation view unifying four entity types via UNION over 3–4 joins each, exposed as a read-only model for native filtering and pagination
• Modernized a legacy PHP codebase to Laravel

Raycast extension for monitoring service status pages, active incidents, component health, and 90-day uptime without leaving the launcher.

• Published in the Raycast Store
• Normalizes 13 status-page providers behind a shared adapter interface
• Handles public APIs, embedded application state, HTML, and RSS fallbacks

Published Model Context Protocol server exposing Monobank accounts, statements, and public exchange rates as typed AI tools.

• Built with the official MCP SDK and published as @alerix/monobank-mcp
• Validates statement windows and normalizes monetary and timestamp data
• Supports token-free access to public exchange rates

npm library porting Android's Material 3 loading indicator to the web with multi-framework bindings.

• Published on npm as @alerix/m3-loading-indicator
• Bindings for Svelte 5, React, Vue 3, and vanilla JS
• Interactive docs site with framework-specific examples

Resolved WXT issue #1567 in PR #2136 by replacing 1-second URL polling with event-driven Navigation API handling, eliminating up to 1 second of SPA route-detection latency while preserving cross-browser compatibility.

Added start, restart, stop, and status commands for dnsmasq; merged upstream as PR #450.
