About

Professional summary

I am a Senior Frontend Engineer with 8+ years of experience building production web applications with React and TypeScript across SaaS, B2B, and B2C products.

I work comfortably from wireframes and mockups through implementation and release, partnering closely with product designers and iterating quickly on feedback. I also enjoy refactoring legacy code incrementally while continuing to ship new features.

My core strengths are modern JavaScript, React, Next.js, browser APIs, styled-components, and performance-focused frontend engineering. I pay close attention to Core Web Vitals, bundle size, responsive mobile-first layouts, and overall user experience.

I also have practical backend and infrastructure exposure through Node.js, REST and GraphQL APIs, Docker, CI/CD, GitHub Actions, and Linux. In addition, I build and ship AI-integrated tooling and have experience with local LLM workflows and OpenAI-compatible APIs.

I have worked on payments, pharmacy benefits, analytics, and design-system-heavy products, and I am comfortable collaborating across product, design, backend, and QA. I value code quality, testing, maintainability, and clear communication.

Outside of client work, I am an open-source author with widely used React and Next.js libraries. I am based in Tbilisi, work remotely, and have a legal entity in place for contracting.

Career history

Senior Frontend Engineer Channels (ChannelTech)

I was the sole frontend engineer on a small product team, owning the entire web frontend in React, Next.js, and TypeScript from design handoff to production.

I worked closely with the product designer from wireframes and mockups onward, prototyped interactions, and iterated based on feedback before release. I also maintained shared components and visual guidelines to keep the product consistent as it grew.

I refactored legacy modules incrementally while shipping new features, improving readability, test coverage, and maintainability. I also built an SEO landing page with structured data and Core Web Vitals telemetry, and added integration and unit tests to previously untested modules.

Frontend Engineer SiliconMint

I built reusable frontend solutions that improved performance and consistency across the product, including a React hook for caching CDN image URLs and a URL-based UI state hook rolled out across 12+ pages.

I also enabled gzip compression on backend API calls, roughly doubling throughput with a single configuration change. In addition, I shipped a new product from scratch for SmithRx, built a custom select component test-first, and stabilized flaky Cypress tests in CI/CD.

I owned a legacy refactor, led cross-functional execution, mentored peers through code review and pairing, and helped clean up Webpack, ESLint, and CI/CD configuration.

Frontend Engineer Omise Co., Ltd.

I architected and maintained a production merchant dashboard for a payments platform using React, GraphQL, and styled-components.

I also prototyped a JavaScript SDK bridging a native mobile wrapper to JS mini-apps and built an internal analytics dashboard with D3.js for telemetry visualization.

I partnered with backend engineers to define API contracts upfront, reduced rework, drove a major UI architecture refactor, and reviewed code across the team.

Frontend Web Developer Ongrad

I maintained two React, Redux, and SSR sites, shipped new features, and fixed responsive markup across screen sizes.

JavaScript Developer Aevrika.ru

I built features in Vue.js and created data visualizations with D3.js and Highcharts. I also fixed bugs and performance issues in existing products.

System Administrator / IT Support Earlier roles

I handled Cisco/VLAN networking, backups, scripting, and IT operations in earlier infrastructure and support roles.
