Paris · Fullstack JavaScript / TypeScript Developer
Open to opportunities — full-time or freelance
I'm Alkhast Vatsaev, a fullstack developer working with React, Next.js and TypeScript. Before code: atelier production (software tools) at Atelier de l'Objet — including work for Cartier and Van Cleef & Arpels. The obsession with detail stayed. My portfolio is built around shipped projects, not inflated titles.
Profile / Fullstack developer in Paris
I build end-to-end web applications with React, Next.js, TypeScript, Node.js and Firebase. My work covers responsive interfaces, backend logic, authentication, databases, payments, third-party APIs, automated tests and deployment.
The projects below demonstrate operational dashboards, logistics workflows, local delivery and interactive 3D product experiences. Each flagship repository includes English documentation, a live demo and automated quality checks. I am available for fullstack, JavaScript, TypeScript, React or Next.js roles in Paris, hybrid or remote.
01 / Selected work
Field-service CRM — heynota.app
Nota is the product I ship for field teams: live job map, mobile technician hub and billing — marketed at heynota.app, app at app.heynota.app.
Full-stack CRM for on-site interventions: dispatch on a map, client files, technician PWA with offline sync, invoicing and role-aware admin. Built with Next.js, TypeScript, Firebase, Mapbox and Stripe.
Field-service CRM & ops PWA
A full operations CRM for locksmith / field teams — dispatch, map, technicians, clients, billing and mobile (admin + terrain). Deep technical sister to Nota.
Next.js App Router product with Firebase Auth/Firestore, Mapbox, offline PWA paths, Stripe subscriptions, multilanguage UI (FR/NL/EN/RU), Jest + Playwright coverage and GitHub Actions CI.
Field operations platform
A full-stack operations workspace for locksmith teams, spanning customer, intervention and technician workflows.
The repository includes role-specific dashboards, mapping, pricing, PDF exports, payments, communications integrations and automated tests.
Interactive 3D configurator
An open-source ring configurator with procedural 3D rendering — built with atelier product craft from Place Vendôme production work.
Users can choose materials, stones, sizes and engraving, then save or share a configuration and export the result as an image.
Logistics workflow
A logistics interface for turning incoming requests into structured, trackable quote workflows.
It connects request intake, enrichment, review, quote pages, tracking links and PDF generation in one responsive Next.js application.
Neighbourhood delivery app
A two-sided grocery delivery experience for creating shopping lists and accepting nearby delivery jobs.
The application covers authentication, maps, job chat, checkout, delivery tracking, proof of delivery and support flows.
02 / Proven stack
I work across frontend, backend services and integrations, choosing tools based on the product rather than collecting labels.
03 / Contact
I'm available to discuss fullstack JavaScript and TypeScript roles, product teams and practical web projects — Paris, hybrid or remote.
