Surik P.

$400K+ earned on Upwork across 56 projects building browser extensions, React/Node.js apps, and automation tools. 100% Job Success. Top Rated 3+ years. 11,000+ hours logged. WHAT I BUILD: Browser extensions are my main thing - Chrome MV3, Firefox, Edge, Safari, Opera. Everything from quick MVPs to complex production extensions with content scripts, background workers, OAuth, and Web Store publishing. Most clients come back for v2 and v3. Web scraping and automation at scale. Puppeteer, Playwright, Selenium. I built a production car-bidding system used daily by multiple auction companies in Georgia (Copart, IAAI, Manheim, ACV) - real-time bid tracking where a 200ms delay can cost a vehicle worth thousands. Running in production for several years. Full-stack apps with React, Next.js, Node.js, TypeScript. SaaS dashboards, internal tools, customer-facing products. I own both frontend and backend without needing to hand off. AI integrations - OpenAI, Claude, DeepSeek, Llama. RAG pipelines, embedded assistants, streaming chat interfaces. Recent work includes DocuFast.ai (workflow capture SaaS - Chrome extension, web app, Electron desktop, and Node.js backend all built by me), CuratelyAI (AI recruiting platform - Chrome extension for LinkedIn profile capture with anti-detection content scripts), and Copyfish (800K+ active users on the Chrome Web Store - one of the most recognized free OCR extensions). HOW I WORK: Day one I read your brief properly, ask the questions that matter, send back a real scope and timeline. No vague estimates. Weekly async updates throughout, with Loom videos for anything visual. If something will run longer or cost more, you hear it from me first. The code I ship is clean and documented. The next dev to open the repo won't have to fight it. WHO I WORK BEST WITH: Funded startups, product teams, and agencies that need a senior engineer who can own a project end-to-end. I'm not the cheapest, but I'm the one who finishes. Send me your brief. I respond within a couple of hours and tell you honestly whether I'm the right fit before we start.
