What is Avaaso?

Avaaso is Ireland's all-in-one rental platform connecting tenants and landlords through smart, data-driven technology.

Built entirely in-house by Xponentshift Limited, Avaaso replaces the chaos of emails and phone calls with verified profiles, commute-based search, joint applications, and an automated viewing calendar.

The Old Way

Hundreds of emails, no verification, manual scheduling, zero transparency.

The Avaaso Way

One verified profile, one click to apply, automated calendar, real-time updates.

Built By

Engineering Breakdown

How XponentShift
Built Avaaso

Designed, developed and maintained entirely in-house — no outsourcing, no third-party agencies.

Product Strategy

Identified the gap in the Irish rental market and designed the full product roadmap from MVP to scale.

Full-Stack Development

Built the entire Next.js frontend and Supabase backend from scratch. All code written and owned by Xponentshift.

Database Architecture

Designed the PostgreSQL schema, RLS policies, and anonymisation views specific to the rental domain.

Security Engineering

Implemented GDPR-compliant data handling, JWT auth flows, row-level security and encrypted storage.

API Integration

Integrated Google Maps API for commute-based search and real-time neighbourhood data.

DevOps & Deployment

Set up Vercel CI/CD pipelines, environment management and production monitoring for zero-downtime releases.

Engineering Challenges

Biggest Technical
Challenges

01

Joint Application Data Sync

Combining multiple tenants' profiles into a single consolidated application in real time, ensuring data consistency across all applicants simultaneously.

02

Real-Time Calendar Conflicts

Preventing double-bookings across multiple landlords and properties required complex slot-locking logic and real-time availability updates using Supabase subscriptions.

03

Commute-Based Search Accuracy

Calculating accurate commute times for hundreds of listings using Google Maps API without exceeding rate limits or degrading page load performance.

04

Anonymisation at Query Level

Serving anonymised tenant data to landlords during filtering while revealing full profiles only on application — required custom PostgreSQL views and RLS policies.
