Ivan Grigoriev

Senior Full-stack Developer at ONO Studio. We design and build custom web & mobile products end-to-end: UI/UX, front-end, back-end, integrations, testing, deployment, and documentation. I assemble the right team for each project (React/Node/PostgreSQL, HTML5/CSS3/JS, plus WordPress/Shopify/Wix/Framer when it’s pragmatic), coordinate delivery, and keep quality high with code reviews, CI/CD, and release checklists. We pay attention to design details (clean typography, responsive layouts, accessibility), performance (Core Web Vitals), and maintainability (modular architecture, clear APIs).

We’ve shipped 30+ projects ranging from landing pages and corporate sites to SPA/MVPs and internal tools. Major references:

• Forex EdTech platform (LatAm) — a large, complex multi-module web platform with student/teacher portals, live streaming, advanced learning modules, and admin tooling on a custom React/Node/PostgreSQL stack.

• Logistics OCR (CIS market) — our own product for automated waybill/invoice processing (Python/Tesseract + integrations) prepared for rollout.

• Light-industry (CIS) — web ecosystem for the textile/garment vertical (catalogs, vendor onboarding, event/landing flows).

I’m comfortable leading builds, clarifying scope, structuring milestones, and delivering production-ready software that looks polished and scales with the business.
