HRABAR YANA
Full-Stack Engineer

Full-stack engineer with 5 years of hands-on experience — from a trainee start in 2021 to owning products end-to-end. I work across the full stack: backend (NestJS, PostgreSQL, Redis, BullMQ), web (React/Next.js) and cross-platform mobile (React Native, Expo), through CI/CD, payments/SMS integrations and store releases. I led mobile development, ran code reviews and mentored junior developers, and I communicate directly with clients. Ready to step into a broader engineering leadership role, and I use AI tools in production daily.
WORK EXPERIENCE
Coderfy — Full-Stack Developer
Sep 2025 – Jun 2026 · Remote
• Owned a production app end-to-end — architecture, NestJS / Supabase (PostgreSQL, RLS) backend and Expo / React Native client with TanStack Query — with no hand-offs.
• Built backend services with Redis for caching and background job queues; integrated payments and SMS (OTP / notifications) end-to-end.
• Set up and ran the delivery pipeline: CI/CD on GitHub Actions, EAS Build/Submit, releases to TestFlight & Google Play, plus Firebase FCM and Sentry.
• Delivered a booking module for a tennis club on a Python backend with a Flutter mobile client — built on university foundations in both, shipping outside the main React/Node stack.
OmnityCode — Full-Stack Developer (grew Trainee → Senior)
Sep 2021 – Sep 2025
• Progressed Trainee → Junior → Strong Junior → Middle → Senior, taking on full-stack ownership: backend APIs, web apps and mobile apps in the same projects.
• Wrote backend services and data layers, built web frontends (React/Next.js) and cross-platform mobile apps (Expo/React Native, TypeScript, NativeWind); owned the release pipeline — builds, automated EAS releases, App Store & Google Play.
• Led mobile development on cross-platform projects (architecture, stack, full lifecycle), ran code reviews, and mentored junior developers — guiding them through tasks and standards.
• Earlier projects: TypeScript migration of a fitness-tracking app (Firebase FCM, FlashList) and an e-commerce app (Firebase Auth, Firestore, Redux Toolkit).
STRENGTHS & LEADERSHIP
• Breadth across the company's exact stack — strong in React, React Native and Node; hands-on with Python and Flutter; comfortable overseeing and reviewing teams across all of them.
• People & delivery — I bring in and coordinate developers, mentor juniors, run code reviews, and speak directly with clients, explaining architecture clearly to technical and non-technical audiences.
• Leadership readiness — I coordinate and review other developers, mentor juniors, own architecture and delivery, and work with AI-assisted workflows; ready to step into a formal engineering leadership role.
