I build React Based browser Extensions with JavaScript/TypeScript. I build Node.js backend for apps, preferably with strapi.io. I follow best coding practices to write code and compile extensions. I have experience working on projects related to Google APIs, Firebase, AWS/MWS APIs, VPS, MongoDB, Express, GraphQL, 0Auth, Selenium, Regex, XPath etc. My interest also extends to developing embedded applications for STM32 MCUs. Having completed scores of successful projects, I am confident about my ability to provide efficient solutions that fit your needs. Let's discuss!

I've shipped 100+ Chrome, Firefox and Thunderbird extensions — and unlike most extension developers, I build the backend behind them too: the APIs, the databases, the scraping, the automation. That second half is where extension projects actually get stuck. A popup is easy. Getting data out of a page, into a queue, through an API, into a CRM and back onto the screen — reliably, at volume — needs a real backend engineer. That's my day job. WHAT I BUILD • Extensions — Chrome, Firefox, Edge, Thunderbird. Manifest V3, content scripts, service workers, OAuth, Chrome Web Store submission and rejection fixes. Including trading and crypto tooling: hotkey and OHLC extensions for Bybit, Bitget and TradingView. • The backend behind them — REST APIs, databases, queues, auth, deployment. Node.js, TypeScript, Go, Python. • Automation & bots — web scraping, data pipelines, Telegram and Discord bots, scheduled jobs, Zapier and n8n workflows with custom code steps. • AI integration — LLM APIs, RAG, and AI features wired into extensions and internal tools. BACKGROUND I'm a Senior Software Engineer building recommendation and analytics infrastructure for a global streaming platform with 20M+ users — Go services handling up to 2M events per minute on ClickHouse, scaled through FIFA World Cup 2026 traffic. I'm also an open-source contributor with merged pull requests in Gin and Echo, the two most widely used Go web frameworks, and in DefinitelyTyped. Working with maintainers on code that thousands of teams depend on is why I care about API design and backward compatibility. Before that: e-commerce scraping pipelines across millions of records, a video streaming and progress-analytics backend, and real-time WebSocket systems. HOW I WORK You describe the problem. I send back a scope, a fixed price and a timeline before any work starts. Milestones, so you're never paying ahead of delivery. Plain-English updates. And I don't disappear — if something breaks after handover, I fix it. STACK TypeScript · JavaScript · Node.js · Go · Python · React · Next.js · Chrome Extension APIs · Manifest V3 · Playwright · Puppeteer · REST · WebSockets · PostgreSQL · MySQL · MongoDB · Redis · RabbitMQ · ClickHouse · Elasticsearch · FFmpeg · Docker · AWS · GCP · n8n · Zapier Tell me what you're trying to build and I'll tell you what it takes — scope, price, timeline. If I'm not the right person for it, I'll say so.

I build web automation systems, scraping and data pipelines, browser extensions, and full-stack SaaS applications that replace repetitive manual work with reliable software. My projects typically combine Next.js/React, Node.js, browser automation, APIs, databases, and cloud infrastructure to take a workflow from data collection through processing, dashboards, and deployment. 𝐖𝐇𝐀𝐓 𝐈 𝐂𝐀𝐍 𝐇𝐄𝐋𝐏 𝐘𝐎𝐔 𝐁𝐔𝐈𝐋𝐃 • Web Automation & Browser Extensions Browser workflows, Chrome extensions, authenticated automation, background jobs, API integrations, retries, queues, and workflow automation. • Web Scraping & Data Pipelines Structured data extraction, complex navigation, pagination, data cleaning, normalization, scheduled collection, APIs, CSV/JSON/database output, and production scraping pipelines. • Full-Stack SaaS & Internal Tools Next.js applications, dashboards, backend APIs, PostgreSQL databases, authentication, role-based access, search/filtering, queues, and deployment. • AI & API Integration OpenAI/Gemini integrations, structured data processing, document generation, enrichment workflows, and AI-assisted automation where it provides practical value. 𝐒𝐄𝐋𝐄𝐂𝐓𝐄𝐃 𝐖𝐎𝐑𝐊 • Built a local-first LinkedIn job automation and resume-generation system using a browser extension, TypeScript/Bun, SQLite queues, OpenAI, and DOCX generation. • Built full-stack scraping and data applications that collect, normalize, store, and expose structured information through APIs and user interfaces. • Worked on production web and mobile applications involving reusable UI, API integration, database workflows, performance improvements, and deployment. 𝐓𝐄𝐂𝐇 𝐒𝐓𝐀𝐂𝐊 Next.js, React, TypeScript, JavaScript, Node.js, PostgreSQL, Supabase, Redis, SQLite, Puppeteer, Playwright, Cloudflare, Docker, REST APIs, GraphQL, and browser extensions. I focus on understanding the business problem first, then choosing the simplest architecture that can work reliably in production. That includes handling failures, retries, data validation, deployment, and maintainability instead of stopping at a proof-of-concept script. If you have a repetitive workflow, difficult data source, browser process, internal tool, or SaaS feature that needs to be built or automated, send me the requirements or a short screen recording. I can help you define the technical approach and build it.
