International type foundry e-commerce (brownfox.org). After RU cards stopped working on international checkout, I built two independent payment paths with automatic provider selection by language/region. | Scope: Next.js App Router, TypeScript, Sanity CMS, Zustand cart. Integrated Stripe, YooKassa, FastSpring, and Lemon Squeezy behind one PaymentProvider interface. FastSpring products created on first purchase (24h cache). Sentry for checkout errors; nginx proxy for reliable access from Russia. | Results: 37 payment/checkout fixes since Jul 2025 (multi-item orders, VAT lines, webhooks). Launched with owners: legal pages, refunds, provider checklists. | Stack: Next.js, TypeScript, Sanity, Sentry, payment webhooks.

Client site for a photographer who needed series to read as one story, not a grid of thumbnails. Site must open reliably for visitors including from Russia. | Built two viewing modes (filmstrip and grid), custom lightbox with swipe (no heavy gallery library), and an image pipeline (sharp → WebP, max width 1920). Deploy and CDN path so the site stays fast and reachable from RU. | Live: banena.ru. I owned delivery from layout handoff to production. | Stack: Next.js 14, TypeScript, Tailwind, custom JS, deploy scripts.

UK contemporary art gallery project. Full communication in English: vague brief → clarified scope → Figma layout → concept pitch → build and SEO to launch. | Responsive Next.js front end, CSS-driven motion (no extra animation library for one screen), SVG art that stays sharp at any scale. Coordinated handoff and performance tuning. | Demo: illiagoncharov.github.io/greenwich/ | Shows: international remote work, product-minded delivery, English C1 with clients. | Stack: Next.js, React, TypeScript, Tailwind, Figma.
