Industry Experience

Retail, Software & Internet, Professional Services
    Pilnasbusas — Shopify store for food and home goods
    A Shopify store for food and home goods — catalog, payments, and day-to-day management without a developer. Brief: A brand selling oil, coffee, and home goods needed a store the team could stock themselves, with reliable checkout and a Lithuanian domain. What I built: A Shopify store: structured catalog, payments, and tailored visuals so the range looks orderly and is easy to buy from. Result: A live store at pilnasbusas.lt — a fixed-scope project ready for day-to-day orders. Case study: https://www.twine.net/signin…
    DAEI birža — B2B renewable energy trading platform (Next.js)
    A B2B trading platform for renewable energy accounting units — from briefing to a live client domain. Brief: The market needed a transparent place to trade and auction DAEI units. A B2B energy audience expects clarity, trust, and speed — not a decorative marketing page. What I built: A Next.js + TypeScript platform with a calm, readable UI, a clear trading flow, and Baltpool-partner messaging. The focus was structure, performance, and helping operators and buyers find the point fast. Result: A live platform on the client domain daeibirza.lt — ready for real trading, not just a demo. Case study: https://www.twine.net/signin…
    Apolobook — Next.js e-book store with Stripe
    A lean Next.js e-book storefront with Stripe — files delivered instantly after payment. Brief: Premium PDF books needed a store without a heavy WooCommerce stack: secure payment, instant download, and a clean brand impression. What I built: A Next.js storefront, Stripe checkout, and file delivery after a successful payment. The design stays calm and readable so the product feels worth the price. Result: A live store at apolobook.com — payments and downloads in production. Case study: https://www.twine.net/signin…
