Three projects from ongoing freelance work: what the problem was, what I built, and what changed. Delivered as part of long-term engagements with international clients.

Sports & Betting
RoleiOS Developer
Duration2021 — 2026

Atlas World Sports

A sports app that kills FOMO by combining live league scores, personalized news, and legal sportsbook betting lines in one place.

Swift UIKit VIP Architecture
Problem

Sports fans needed one place to track live scores, personalized news, and their sportsbook bets without missing a moment.

Approach

Owned the entire app lifecycle — concept, design, testing, App Store release, and support — building a VIP + Coordinator architecture with Clean Code and 90%+ test coverage, setting up the CI/CD pipeline, shipping push notifications and API-based live score updates, and regularly advising the PM and backend team on what to build and how.

Outcome

A production app that shipped live scores, personalized news, and betting-line tracking to the App Store; later rebuilt by a new team as the product evolved.

02
Backend & POS Integrations
RoleSwift Developer
Duration2023 — 2026
URLwisk.ai ↗

Wisk

The leading restaurant management platform — analytics, recipe costing, and bar inventory software for running a bar or restaurant with ease.

Swift Vapor PHP Kotlin
Problem

Wisk's analytics, recipe costing, and inventory tools are only as accurate as the POS data feeding them, and operators run on dozens of different systems.

Approach

Built and maintained backend integration services in Swift, Vapor, PHP, and Kotlin, connecting over 30 POS systems — including Lightspeed, Square, Toast, and Clover — over API, email, and file-based feeds, while reviewing code to keep the integrations consistent and maintainable.

Outcome

30+ POS systems integrated and kept in sync, feeding accurate, real-time data into Wisk's platform for bar and restaurant operators.

03
Marketplace

DurationOct 2021 — Jul 2022
URLzenjob.com ↗

Zenjob

A digital staffing marketplace where talents book flexible, hourly jobs and companies fill temporary shifts across logistics, e-commerce, retail, and service.

Swift UIKit
Problem

Companies needed flexible, on-demand staff, while workers wanted control over when, where, and for whom they worked.

Approach

Owned the entire app lifecycle — concept, design, testing, deployment, release to stores, and support — implementing UI in close collaboration with designers.

Outcome

Shipped a production iOS app helping power a platform booking 40,000+ workers a month across logistics, e-commerce, retail, and service roles.
