Oleksandr Vakulinskyi
@oleksandrvakulinskyi
I build subscription-driven SaaS products and full-stack web applications.
UkraineWhat I'm looking for
I've delivered SaaS products for international clients at Interlink since 2021, building subscription systems, role-based access, analytics, and integrations across React, Node.js, PostgreSQL, Stripe, and AWS.
For a no-code mobile and web app builder, I upgraded Stripe-based feature gating, implemented locale-based discounts, and helped migrate millions of database records. I also built a standalone service that converts Google Sheets into protected REST API endpoints through Google OAuth.
On an Active Directory and Office 365 management SaaS, I built subscription and pricing functionality, redesigned registration into a multi-step flow, and added Azure AD reporting, onboarding, and permission gates.
I've also improved Stripe pricing for a content marketplace, stabilized a WordPress corporate website, and automated Apigee proxy and API test generation with Cursor AI skills.
