TypeORM, and built Next.js frontend — sole engineer responsible for taking the platform from zero to
production
• Designed normalized relational data models for properties, tenants, lease agreements, and operational
workflows — structured entities to eliminate N+1 queries and support complex cross-entity reporting without
performance degradation as dataset grew
• Implemented multi-layered RBAC system with granular permission levels for admin and staff roles — replaced
a manual, spreadsheet-based access-control process and eliminated unauthorized data exposure across
sensitive tenant records

relational database — ensured scalable, reliable infrastructure capable of handling property documentation,
tenant contracts, and operational attachments from day one
• Integrated third-party notification APIs to automate tenant communication and staff alert workflows previously
managed manually via spreadsheets — directly reduced operational overhead on the client side and
eliminated missed notifications
• Engineered server-side rendering with Next.js to optimize initial page load performance and SEO across
property listing pages — ensured platform was accessible and indexable without client-side rendering delays
• Implemented JWT-based authentication with secure session management — designed token refresh flow and
route-level protection across all frontend pages, ensuring zero unauthorized access to sensitive property and
tenant data
Tech stack: Next.js, NestJS, TypeORM, Node.js, PostgreSQL, AWS (S3, RDS), REST API, Tailwind CSS, 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

• Built the complete QR-driven ordering flow end-to-end — customer scans → browses dynamic menu →
places order → pays → receives receipt — achieving zero staff intervention at point of service and reducing
average order processing time by ~40% compared to manual table service
• Integrated Vipps payment gateway into the order processing workflow, handling payment intents,
confirmations, failure recovery, and receipt generation across single locations and multi-venue chains —
ensured 100% of transactions processed without manual reconciliation
• Developed Excel-to-database import pipeline that parsed and transformed existing menu data into structured
DB entities — cut restaurant onboarding time from days to under 2 hours, enabling rapid rollout across new
venues without engineering involvement
• Implemented multi-role authorization system (customer / staff / admin) with permission-gated UI and JWT
session management — ensured zero unauthorized access to back-office management across all deployed
locations
• Built dynamic menu system supporting multi-level categories, item variants, allergen tags, and per-location
overrides — enabled chains with 10+ venues to manage menus independently, reducing menu update time
from hours to minutes
• Architected GCP-hosted backend with Cloud Functions for serverless order processing — designed to handle
peak-hour traffic spikes without manual scaling, keeping infrastructure costs proportional to actual usage
Tech stack: React, Express.js, Vipps, GCP, Ant Design, SendGrid
Letme — Multi-Platform Operations Management System
Letme is a multi-application platform (3 web + 2 mobile apps) designed to help companies manage internal

mobile (React Native) — in a shared ecosystem, enforcing patterns that reduced cross-team integration
friction
• Contributed to NestJS backend services with TypeORM data layer powering core operational workflows
across the entire platform
• Replaced slow database LIKE queries with Typesense full-text search — achieved sub-100ms filtering across

structures where teams required isolated but interconnected environments, reducing access-related support
requests to zero
• Built real-time collaboration layer using Firebase (live task updates, presence indicators, concurrent editing)
— eliminated manual page refreshes and enabled true simultaneous multi-user editing across distributed
teams
• Owned frontend state architecture ensuring consistent sync between real-time Firebase events and REST API
responses — eliminated race conditions and stale state in concurrent multi-user sessions
• Implemented skill-based developer assignment engine that matched incoming tasks to team members based
on declared expertise — reduced manual assignment overhead for project managers by automating routine
allocation decisions
• Architected automated task estimation module that analyzed task parameters and historical data to generate
time estimates — reduced planning session duration and gave stakeholders more predictable delivery
timelines
• Integrated SendGrid transactional email pipeline for workspace invitations, task assignment notifications, and
deadline alerts — replaced manual communication workflows and ensured zero missed handoffs across
async teams
• Contributed to REST API design supporting workspace, task, and user management — built endpoints that
decoupled frontend state from backend operations and enabled future mobile client expansion without API
changes

design handoffs entirely and gave the sales team autonomy to produce client-ready materials without any
engineering involvement
