Frontend Engineer · React & Next.js

I build production web apps for a white-label logistics platform used by multiple courier companies. Over the past years I rebuilt its customer portal and back-office admin from legacy React into Next.js — from order creation and payments to invoicing, reconciliation and per-carrier theming.

Experience

Feb 2024 — Present

Frontend Developer · Koder

Frontend lead on Accura, a polyglot logistics monorepo (Next.js, React, PHP/Symfony, Go, Android). Each app is built and deployed once per courier company with its own config, branding and features.

  • Started the Next.js customer portal from scratch and migrated it, feature by feature, off the legacy CRA app.
  • Rebuilt the back-office admin in Next.js App Router, replacing parts of a React 17 app and a C# desktop client.
  • Kept the legacy React 17 / Redux / PrimeReact apps running in production during the migration.
  • Kept every app on the latest Next.js and React — most recently Next 16.4 / React 19.3 with Zod v4.

Customer Portal

Self-service portal where businesses and individuals create, pay for and track shipments. I built it from the first commit and migrated users over from the legacy app.

  • —Order creation for parcels, letters, court documents, express delivery and parcel lockers
  • —Bulk order import, group actions, label & sticker printing, QR codes
  • —Card payments, invoices, COD and payer eligibility rules per carrier
  • —Parcel locker map with live slot booking
  • —Auth flows with httpOnly cookies, server-only API layer, security headers
  • —Installable PWA, mobile-first navigation, dark mode, per-tenant theming
  • —Smooth handoff between the old and new portals during rollout

Manager — Back-office Admin

Internal app for courier staff: orders, logistics, warehouse reception, finance, clients, billing and reporting. It's gradually replacing a legacy React app and a desktop client.

  • —Order create/edit with scrollspy sections and live client search
  • —Price list & tariff authoring with a formula builder
  • —Invoice e-signing with a PKI token via NexU
  • —COD payouts, courier reconciliation, cashdesk & warehouse reports
  • —Barcode / QR PDF export, weight-scale and smart POS terminal integration
  • —SSO handoff between the legacy and new admin apps
Next.js · No auth

Public Shipment Tracking

Public tracking page for recipients. I moved it to the same architecture as the portal and admin and redesigned the status history UI.

  • —Status timeline with location, description and courier comments
  • —Server-only endpoints and tenant-specific branding
React 17 · Redux · PrimeReact

Legacy Apps

Maintained and extended the CRA-based customer and admin apps that are still in production while their replacements roll out.

  • —Table filters, data tables, CSV export, direct label printing
  • —Incomplete-order workflows, holidays, sorting machine config
