Hi, my name is

Bahdasar Ovsepian

I build things for the web.

I'm a front-end developer at AWERTI, where I build livestreaming and esports analytics products — Esports Charts, Streams Charts and a handful of others — used by teams, studios and sponsors to make sense of millions of hours of watch time.

My day-to-day is Laravel with Livewire on one side and Nuxt with Vue and TypeScript on the other, turning ClickHouse-scale datasets into interfaces that stay fast, accessible and pleasant to use.

About Me

Hello, my name is Bahdasar Ovsepian and I build data-heavy things for the web. My passion for programming started in high school, where I taught myself to code in my spare time — and I have been shipping ever since.

For the past few years I have led the front-end of a portfolio of esports and livestreaming analytics products, turning ClickHouse-scale datasets into dashboards, charts and reports that people actually enjoy using. In practice that means Laravel with Livewire, Blade and Tailwind on one side, Nuxt 4 and Vue 3 with TypeScript on the other, and a fair amount of Docker, testing and performance work in between.

The subject followed me off the clock. I took a master's in esports at the National University of Ukraine on Physical Education and Sport, wrote my thesis on how streaming platforms shape the popularity of esports, and co-authored two conference papers on the same question. It is an odd pairing on paper and a useful one in practice — most of the arguments worth having at work are about what a viewership number actually means.

I enjoy the parts of the job that sit between disciplines: migrating a legacy app to a new stack without taking it offline, agreeing on an API contract with the back-end, chasing down a Core Web Vitals regression, or building internal tooling so the whole team ships faster. Outside of work I build small things end to end — browser extensions, Telegram bots, retail kiosks and a few open-source CLI tools.

If you would like to know more about my work, or you have a project you think would benefit from my expertise, take a look at my GitHub profile or reach out on LinkedIn.

Here are a few technologies I’ve been working with recently:

Where I’ve Worked

Front-end Developer @ AWERTI

Oct 2022 – Present

  • Lead the front-end across a portfolio of livestreaming and esports analytics products — Esports Charts, Streams Charts, ChessWatch, DoHuya, TikTok Stats, Visit Esports and Stream Awards.
  • Build and maintain Laravel + Livewire applications: Blade components, Tailwind, Alpine.js and a shared design system reused across all products.
  • Render analytics over ClickHouse and MySQL — dashboards, comparison views, interactive charts and CSV/PDF report exports for millions of rows.
  • Migrate legacy Laravel + Livewire products to Nuxt 4 (Vue 3, TypeScript) on Cloudflare Workers, planning the work stage by stage and keeping the live sites shipping throughout.
  • Ship browser extensions on Vue 3 + TypeScript + Vite, published to the Chrome Web Store and Firefox Add-ons.
  • Cover features with Pest/PHPUnit, Vitest and Playwright (including visual regression baselines), and keep the pipelines green in CI.
  • Work locally against a Dockerized Laravel stack (nginx, PHP, Redis, queue workers, ClickHouse), maintaining the shared compose setup.
  • Own front-end quality gates: HTML/WCAG validation, Lighthouse and Core Web Vitals budgets, and QA on a real iOS WebKit engine via the iOS Simulator.
  • Gate paid chart groups by subscription plan on both client and server, and wire up Sentry error reporting and GTM click tracking across the dashboards.
  • Translate Figma designs into pixel-accurate, responsive and accessible markup, and agree on the API/props contract with back-end developers.
  • Build internal tooling that speeds the whole team up — a shared Claude Code plugin marketplace, a CLI for iOS Simulator QA, and a Slack bot for content-readiness notifications.

    Spoloh

    A self-hosted appliance that announces air raid alerts and scheduled events over an existing PA system or speaker. Runs on a Raspberry Pi or Orange Pi with no cloud, account or vendor: it cascades between several alert providers (including ukrainealarm.com), raises its own Wi-Fi access point when it loses the network, and updates itself from verified releases. Schedules with repeat windows, webhooks and configuration backups are managed from a built-in web dashboard.

    Oksana ERP Importer

    A self-hosted web app that turns incoming supplier invoices into drafts in a legacy MSSQL ERP. Around 60 supplier-specific parsers, bound to firms by their EDRPOU code, read PDF, XLSX, TXT and waybill layouts — down to barcodes drawn as images. Invoices arrive by upload or straight from the mailbox; a goods lookup, payment sheets and screens that surface silent failures sit around the import. Nuxt 4 with its own Postgres for users, sessions, shops and an audit log; the ERP is read through a least-privilege login and written to only via whitelisted stored procedures. One deployment serves several stores, each shop server redeploying itself nightly.

    • Nuxt 4

    A read-only security audit tool for Dahua IP cameras. It finds rogue accounts left behind on compromised devices by botnets, reports firmware versions and flags risky settings — without changing anything on the cameras. Zero runtime dependencies (Python standard library only), with one-file binaries built for Windows, macOS and Linux.
