Alfabolige — Property Management Platform
Property management platform for organizations managing rental properties, tenants, and operational workflows for
socially supported housing.

• Built the complete Next.js frontend from scratch — page architecture, routing, SSR configuration, and
component structure — taking the platform from zero to production as the sole frontend engineer
• Implemented server-side rendering (SSR) across property listing and tenant management pages — optimized
initial page load and ensured full search engine indexability without client-side rendering delays
• Designed and built permission-gated UI for admin and staff roles using RBAC — each role received a tailored
interface with restricted views, replacing a manual access process with a governed, role-aware frontend
• Built responsive document management UI with file upload flows integrated with AWS S3 — enabled staff to
attach and retrieve tenant contracts and property documentation directly from the interface
• Integrated notification APIs into the frontend workflow — automated in-app and email alerts for tenant
communication, replacing spreadsheet-based manual processes and reducing response time
• Implemented JWT authentication flow on the frontend — built token refresh logic, protected route guards, and
session management across all pages ensuring zero unauthorized access
Tech stack: Next.js, React, TypeScript, Tailwind CSS, REST API, JWT

Pick Your Pour
QR-Based Restaurant Ordering Platform. F&B platform for multi-location restaurant chains. Full order lifecycle: scan
→ browse → order → pay → receipt

menu → cart → Vipps payment → receipt — achieving zero staff intervention at point of service
• Developed dynamic menu UI supporting multi-level categories, item variants, allergen tags, and per-location
overrides — enabled chains with 10+ venues to manage menus independently with real-time updates
• Built multi-role UI (customer / staff / admin) with permission-gated views and JWT session handling —
ensured zero unauthorized access to back-office management screens across all deployed locations
• Integrated Vipps payment UI into the order flow — handled payment intent states, loading indicators,
confirmation screens, and error recovery ensuring a seamless end-to-end checkout experience
• Developed staff-facing order management dashboard with real-time order updates — gave kitchen and
front-of-house teams live visibility into incoming orders without page refresh

developed apps — 3 web (React) and 2 mobile (React Native) — reducing cross-team integration friction and
onboarding time
• Built shared UI component library used across all 5 apps — enforced visual and behavioral consistency,
eliminated duplicate implementations, and accelerated feature development across the ecosystem
• Integrated Google Maps API and Mapbox into the React frontend for vacancy management — built interactive
map views enabling operations teams to visualize and assign vacancies geographically in real time
• Integrated OneSignal push notifications into both web and mobile frontends — replaced manual notification
workflows with real-time in-app alerts, improving staff response time across the platform
• Built automated PDF generation and rendering pipeline on the frontend — paired with SendGrid delivery,
reduced notification lag from hours to seconds
• Connected frontend to Typesense full-text search — replaced slow filtered list UIs with sub-100ms search
results across large operational datasets, significantly improving usability
Tech stack: React, Next.js, React Native, TypeScript, REST API, Google Maps API, Mapbox, OneSignal

editing across distributed teams, eliminating manual page refreshes entirely
• Owned frontend state architecture for real-time sync between Firebase events and REST API responses —
eliminated race conditions and stale UI state in concurrent multi-user sessions
• Built workspace hierarchy UI (parent/child workspaces) with granular RBAC-driven views — supported
complex org structures where teams required isolated but interconnected environments
• Developed skill-based developer assignment UI — allowed project managers to configure expertise tags and
automated task routing, reducing manual assignment overhead significantly
• Built interactive task estimation interface that surfaced AI-generated estimates based on task parameters and
historical data — reduced planning session duration and gave stakeholders more predictable timelines
• Designed and implemented SendGrid-triggered notification UI for workspace invitations, task assignments,
and deadline alerts — ensured zero missed handoffs across async distributed teams
Tech stack: React, TypeScript, Firebase, Ant Design, REST API
 Senseteq Admin App — Internal Project & Client Management System
Internal platform for managing company projects, client pipeline, team allocation, commercial offers, and brand
materials.
