Mykyta Tretynko

I’m a Full-Stack Web Developer with 6+ years of hands-on experience designing, building, and scaling web applications for startups and SaaS businesses. My core stack is PHP (Laravel/Yii2) on the backend and React/Vue on the frontend, with TypeScript where it adds safety and clarity. I focus on clean architecture, reliable data models (MySQL), and predictable delivery: from discovery and scoping to deployment and ongoing optimization.

On the backend, I’ve implemented multi-tenant SaaS features, role-based access control, background jobs/queues, and RESTful APIs consumed by web and mobile clients. I’m comfortable with database schema design, query optimization, and stored procedures when they serve performance. I’ve integrated third-party services extensively—Stripe, PayPal, Google APIs, and 30+ external endpoints for data sync, payments, and marketplace distribution. I write testable code, keep dependencies tidy, and use Git and code review to maintain quality.

On the frontend, I build responsive, component-driven interfaces with React or Vue, paying close attention to state management, accessibility, and performance. I aim for UI that stays fast under real traffic and product teams can evolve without friction. I’m pragmatic about tooling and keep the stack as simple as it can be, but no simpler.

I’ve helped launch and grow SaaS products with real traction. One real estate platform I worked on reached about 25,000 monthly users and generated $500K+ in monthly subscription revenue. It included a connected web app, mobile client, CRM, marketing automation modules, end-to-end deal processing, and automated multi-listing to 30+ marketplaces—all tied together through robust APIs and payment integrations. In the education space, I delivered a platform serving 28,000 users and averaging €100K in monthly revenue. There I implemented document-generation workflows (including PDF creation), a rules-based system for routing and approvals, an internal bonus currency, and a set of services to recognize document metrics, with Stripe/PayPal for billing.

Beyond greenfield work, I’ve modernized legacy systems, including migrations from Yii to Laravel with a Vue front end, lifting paper-heavy, form-based processes into fully digital flows. I’m comfortable owning the full lifecycle: architecture, implementation, CI/CD, observability, and post-launch iteration based on product metrics.

I’m based in Ukraine and work remotely with a clear communication style, reliable delivery routines, and a habit of documenting what matters. Whether it’s standing up an MVP quickly or hardening a growing product for scale, I bring a calm, systematic approach and a bias for shipping.
