About me

Senior Full-Stack Web & Mobile Developer focused on building scalable, high-performance web and mobile applications. Strong expertise in React, React Native, Next.js, Node.js and application architecture.

Experienced in technical leadership, cross-platform development and delivering production-ready solutions for startups and international clients in remote and hybrid environments.

What I can build for you

React Native app development

Cross-platform iOS & Android apps from a single codebase — push notifications, deep links, offline-first, native modules and a smooth App Store & Google Play release.

Web apps & websites

Fast, SEO-friendly products with React and Next.js (SSR / SSG / ISR) or Vue / Nuxt — tuned for Core Web Vitals, accessibility and conversion.

Backend & APIs

REST and GraphQL APIs with Node.js, NestJS or Laravel — JWT auth, role-based access, WebSockets, file uploads and well-designed PostgreSQL, MongoDB or Firebase data.

CMS, admin panels & dashboards

Internal tools your team actually enjoys: data-heavy tables, filters, inline editing, roles and analytics — plus CMS that change your app without a release.

Technical leadership

Architecture decisions, task breakdown and estimation, code review and mentoring. I've led a team of 5 developers and delivered on deadline.

Performance & rescue

Slow app, messy codebase, stuck release? I profile, refactor and optimize — like the 20% performance boost I delivered through database query optimization.

Featured projects

• Voxa — AI voice notes app for iOS, Android & Web

  Speak, and AI turns your voice into a clean note — title, summary, task list, reminders with exact times and tags. One React Native codebase for iOS, Android and the web, with a live demo you can try right here.

• Slotly — Booking & CRM for beauty salons, with an AI assistant

  Online booking, an AI booking assistant, a staff mobile app and a CRM for beauty salons — all on one real-time data layer. Book on the client site and watch the appointment land in the stylist's app instantly.

• Loudey — Social audio network for iOS & Android

  A voice-first social network: users record short voice "casts", reply in threads, follow trending topics and message privately — shipped to the App Store and Google Play with React Native.

• Altermeliora — Web platform, CMS, admin panel & mobile app

  A full product ecosystem built end-to-end: the user-facing web platform, a CMS for content and app configuration, an analytics admin panel and a cross-platform mobile app — plus a 20% performance gain from database optimization.

Full resume

Why teams hire me

One developer for web + mobile

React and React Native under one roof means shared logic, consistent UX and less code to maintain.

Product mindset

I think about the end user and the business goal first, then pick the technology.

From idea to store release

Architecture, development, CI/CD and publishing to the App Store and Google Play.

Clear communication

Remote-first since 2018. Armenian, Russian and English. Predictable estimates, no surprises.

Questions clients ask

Are you available for freelance or contract work?

Yes. I take on freelance and contract projects — from building an MVP to joining an existing team. Send me a short description via the contact form, Telegram or email and I'll get back to you quickly.

Can you build an app for both iOS and Android?

Yes — that's my specialty. With React Native I build one codebase that runs natively on iOS and Android, and I can also share logic with a React or Next.js web version.

Which technologies do you work with?

React, React Native, Next.js, TypeScript and Node.js are my core stack. I also work with Vue / Nuxt, NestJS, Laravel, GraphQL, PostgreSQL, MongoDB, Firebase, Docker, AWS and CI/CD.

Where are you based and what time zone do you work in?

I'm based in Yerevan, Armenia (GMT+4) and work remotely with teams and clients around the world, with comfortable overlap for calls across time zones.

Can you take over or improve an existing project?

Absolutely. I regularly audit, refactor and optimize existing codebases — improving performance, stability and architecture without stopping feature work.
