Full-Stack Engineer
From idea to fully working product.
I design, build, deploy and maintain production web and mobile systems for businesses.
For 14+ years I've been building production IT systems for businesses — mostly CMS and ERP platforms across web, mobile, backend and DevOps.
I operate as the systems architect: translating business requirements into technical solutions, owning structure and strategy, and looking after the full lifecycle from planning to deployment and monitoring. Some projects are under NDA — I can walk through the problems, architecture and outcomes.
On-Demand Parcel Delivery
ZippAn Uber-style peer-to-peer parcel delivery app for Lithuania. Senders post packages with map-picked pickup/drop-off and pay upfront; drivers browse jobs on a live map, negotiate prices and deliver with real-time GPS tracking. Bilingual (EN / LT), EUR-based.

MemowriteA personalized memoir product that turns guided life-story questions into professionally printed hardcover books. AI refines the writing and restores old photos, with print-on-demand fulfillment and an 8-language admin back office.

EV Charger Sharing
ChargeShareAn app connecting EV drivers with people who share their chargers. Drivers find chargers on a clustered map, mutually match Tinder-style, book real availability slots and pay via Stripe Connect.

Government Resources Management
An internal system for government agencies to track contractor costs and delivered services across sectors, with strict role-based access, monthly filterable reporting and audited account provisioning.
Restaurant Operations Suite
A full-stack restaurant operations suite spanning tables, orders, inventory and staff, plus a customer mobile app for menus and live order tracking. WebSockets keep everyone in sync; Stripe handles checkout.
