Last updated: 2026-08-29. Canonical: . ## Summary Senior Frontend Engineer with 8+ years shipping production React and TypeScript across SaaS, B2B, and B2C, including three years on a payments platform. Picks work up at the wireframe and mockup stage, prototypes the interactions with product designers, and stays on it through implementation and release. Refactors legacy code incrementally while delivering new work. Strongest on the parts of a frontend that decide whether it is still workable a year later: component libraries, state management, and test suites that catch real regressions. Performance-focused — tracks Core Web Vitals, reduces bundle size and network requests, builds responsive mobile-first layouts. Comfortable past the browser, with services running to prove it: a Cloudflare Worker + D1 analytics backend (schema, idempotent ingest, token-gated read API, nightly retention cron), an OpenAI-compatible HTTP queue for local LLMs, a record-and-replay proxy for Playwright covering SSR, browser and WebSocket traffic, and a poisoning-resistant consensus cache that runs on either Workers/D1 or Node/SQLite from one set of handlers. Also ships AI-integrated tooling: an agentic scrape-and-extract pipeline and an on-device LLM content classifier. Earlier background as a system administrator (Cisco/VLAN networking, servers, backups, scripting), which is where the CI/CD and infrastructure comfort comes from. ## Availability and engagement - **Status:** Available now. - **Sought:** Full-time remote role, 40 hrs/week. Employment, EOR, or B2B contract — whichever is simplest on your side. - **Location:** Tbilisi, Georgia (GMT+4). Full CET overlap; comfortable with EU hours and partial US overlap. - **Work authorization:** Georgian residency permit granting the right to work as a contractor for non-Georgian companies. Registered Georgian legal entity and business bank account already in place, so B2B contracts and invoicing need no employer-of-record setup. - **Engagement models:** Full-time employment (incl. via EOR), B2B contract through the entity, or fixed-scope project. Each one written out — who you contract with, what the paperwork is, how invoicing works — at . - **Languages:** English C1 (full professional), Russian native. ## Key pages - **How to hire me:** — engagement models, work authorization, timezone, and the answers to the questions recruiters ask first. - **About:** — the career arc from system administrator to senior frontend engineer. - **Projects:** — case studies for the libraries and the commercial work. - **Résumé:** - **Blog:** ## Contact - **Email:** [asmyshlyaev177@gmail.com](mailto:asmyshlyaev177@gmail.com) - **Telegram:** @asmyshlyaev177 - **Phone:** +995 599 995 121 - **GitHub:** [asmyshlyaev177](https://github.com/asmyshlyaev177) - **LinkedIn:** [asmyshlyaev177](https://linkedin.com/in/asmyshlyaev177) - **Website:** [asmyshlyaev177.dev](https://asmyshlyaev177.dev) - **Résumé (PDF):** ## Verifiable claims Every headline number below can be checked from a public source without asking me for anything. Where a figure comes from an API, the API endpoint is listed rather than the human page — those return JSON, need no key, and are what the number here was read from, so a mismatch is a real one and not a rendering difference. | Claim | Where to verify | | --- | --- | | ~111k weekly npm installs, react-horizontal-scrolling-menu | · | | 788 GitHub stars | · | | 20k+ dependent repositories, react-horizontal-scrolling-menu | | | Our World in Data renders its key-insights slider with it (`^8.2.0`) | | | Precious Plastic / ONE ARMY builds `VerticalList` on it (`^8.2.0`) | | | erxes uses it for the point-of-sale category menu (`^4.0.4`) | | | Reapit uses it for the app-builder viewport tab bar (`^3.2.5`) | | | AWS's Performance Dashboard solution uses it for dashboard tabs (archived 2024, pins `^2.1.1`) | | | 418 stars, ~7.2k weekly installs, state-in-url | · | | 116 stars, test-proxy-recorder | · | | Recommendations from a CTO, a CPO, and a senior PM | | **On the dependents count.** That page is GitHub's own dependency graph — it reads the lockfiles of public repositories, and the total at the top of it is where "20k+" comes from — labelled approximate by GitHub itself. Two things to know before you read it. It cannot be sorted, so the first screen is whatever it lists first, mostly small projects; the dependents worth looking at are the five rows above, each linked to the `import` in the component that uses it, pinned to a commit so the line stays right. And third-party indexes report far less — ecosyste.ms around two thousand repositories, Google's deps.dev fewer still — because they crawl a subset of GitHub, and deps.dev counts dependent *packages* rather than repositories. They are measuring different populations, not correcting GitHub. Take GitHub's number, approximate as it says it is. ## Professional experience ### Senior Frontend Engineer — Channels (ChannelTech), Tbilisi | 10/2024–05/2026 B2B hiring platform. - Sole frontend engineer on a 3-person product team (one backend, one mobile), owning the entire web front end in React, Next.js, and TypeScript from design handoff to production on continuous deployment. - Worked with the product designer from wireframes and mockups onward, prototyped new interactions, iterated on feedback before release. - Maintained the shared component set and visual guidelines so styling stayed consistent as the app grew. - Refactored legacy modules incrementally while shipping new features. - Built an SEO landing page with structured data and Core Web Vitals telemetry: Lighthouse 95 performance / 96 accessibility / 100 best practices / 100 SEO. - Added integration and unit tests (Playwright, Jest) to previously untested modules. ### Frontend Engineer — SiliconMint, Tbilisi | 05/2022–10/2024 - Built a reusable React hook for caching CDN image URLs, reducing network requests and improving page load times product-wide. - Enabled gzip compression on backend API calls, roughly doubling throughput with a single configuration change. - Shipped "Find My Meds" from scratch for SmithRx (pharmacy benefits platform): search with filters, results list, Google Maps integration, fully tested. - Built a custom select component test-first with Cypress component testing, reused as a design-system primitive. - Developed a reusable URL-based UI state hook, rolled out across 12+ pages. - Tracked down and fixed flaky Cypress tests in CI/CD, stabilizing the pipeline. - Owned a legacy refactor: scoped the plan in Jira, led cross-functional execution. - Mentored peers through code review and pairing; cleaned up Webpack, ESLint, and CI/CD configuration. ### Frontend Engineer — Omise Co., Ltd., Bangkok | 06/2019–03/2022 Payments platform (Southeast Asian payment gateway). - Architected and maintained the production merchant dashboard in React, GraphQL, and styled-components — the surface merchants use to watch their own money move, so the correctness bar sat higher than typical CRUD UI. - Prototyped a JavaScript SDK bridging a native mobile wrapper to JS mini-apps. - Built an internal analytics dashboard with D3.js for telemetry visualization. - Partnered with backend engineers to define API contracts upfront, reducing rework. - Drove a major UI architecture refactor and reviewed code across the team. ### Frontend Web Developer — Ongrad | 06/2018–11/2018 - Maintained two React, Redux, and SSR sites; shipped features and fixed responsive markup across screen sizes. - Wrote the first version of react-horizontal-scrolling-menu in this role — a design needed a horizontal scrolling menu no library covered. Now 788 GitHub stars and ~111k weekly npm downloads. ### JavaScript Developer — Aevrika | 01/2017–01/2018 - Built features in Vue.js and data visualizations with D3.js and Highcharts. ### System Administrator / IT Support | 09/2010–01/2016 - Cisco/VLAN networking, backups, scripting, IT operations. ## Open-source work ### react-horizontal-scrolling-menu 788 stars · ~111k weekly npm installs · 20,000+ dependent repositories. Shipped by [Our World in Data](https://github.com/owid/owid-grapher), [Precious Plastic](https://github.com/ONEARMY/community-platform), [erxes](https://github.com/erxes/erxes), [Reapit](https://github.com/reapit/foundations), and AWS's [Performance Dashboard](https://github.com/aws-solutions/performance-dashboard-on-aws) solution. A horizontal scroll primitive for React. Inherited the library, rewrote the core in TypeScript, added tests and Storybook, and kept the public API stable through React 17, 18, and 19 — years of maintenance without forcing a breaking change on downstream users. - GitHub: - npm: - Site: - Demo (Storybook, live-editable): ### state-in-url 418 stars · ~7.2k weekly npm installs · zero dependencies. Keeps nested, typed React state in the URL, so filters, multi-step forms, and expanded panels survive a reload and can be shared as a link. Sole author: designed the hooks API, wrote the TypeScript core, built the docs site, handles every issue and release. Stable across Next.js, Remix, and React Router, and through multiple React majors. - GitHub: - Demo: ### test-proxy-recorder 116 stars. VCR-style record-and-replay testing for Playwright. Captures real API traffic once across Next.js SSR, browser, and WebSocket transports, then replays it deterministically in CI with no backend running. Solves the problem that makes integration suites flaky: tests that depend on live services. - GitHub: - Site: ### llm-queue Single-worker priority queue for local LLMs (Ollama), exposed as an OpenAI-compatible HTTP service so cron jobs, browser extensions, and OpenAI clients all share one serialized queue against a single model. Published on npm with a CLI. - GitHub: ## Systems built and operated ### heatmap-analytics — Cloudflare Workers + D1 Self-hosted behaviour analytics: click and hover heatmaps, scroll depth, rage-click detection and ghost-cursor session replay, with no cookies and no third-party scripts. Sole author of the schema, the ingest path and the read API. Beacons batch through one `sendBeacon` and are idempotent on a `(pageview, sequence)` unique constraint, so a retried flush cannot double-count; reads are token-gated; a nightly cron purges past the retention window. The 1.7KB tracker anchors every event to a CSS selector rather than to page coordinates, so heatmaps survive responsive breakpoints and content edits. - GitHub: ### Shared location cache — Workers + D1, or Node + SQLite A crowdsourced cache in front of a rate-limited third-party API, keeping every client under the limit. One set of request handlers runs on either backend through a small database interface, so the same code deploys to Cloudflare, to systemd on a VPS, or to Docker. Poisoning-resistant by consensus: one latest vote per client per key, with confidence measured as the number of distinct clients backing the winning value. - GitHub: ## Commercial project case studies ### Omise — payments merchant dashboard Three years architecting and maintaining the merchant-facing dashboard for Omise's payments platform. React, GraphQL, styled-components, plus an internal D3.js analytics dashboard and a JavaScript SDK bridging a native mobile wrapper to JS mini-apps. Ran in production throughout, including across a major architecture refactor. Agreeing API contracts with backend before implementation cut rework between the two sides. ### channels.careers — B2B hiring platform Sole frontend engineer. Next.js and TypeScript UI built to match design closely, a shared-state refactor, mobile adaptation, and the Playwright suite the team gates releases on.
