Remote — Wyoming, United States

• Shipped AI-native products end to end — including Vikki Wikki, an AI travel product taken from concept validation through UX architecture and technical execution.
• Built an AI-integrated 3D fashion canvas enabling users to create, visualise, and modify garments (shapes, colours, materials, patterns) interactively, with foundations for virtual fitting and fabric simulation.
• Integrated LLMs and third-party AI services into product workflows, improving AI accuracy, reliability, performance, and cost efficiency.
• Owned architecture, APIs, and data workflows; built prototypes and MVPs to validate ideas quickly and directly with users.
• Drove a retail-media advertising system with data-driven targeting, pacing, budgeting, and forecasting — connecting campaign delivery with sales, weather, location, and performance data.

Remote — Dublin, Ireland

• Sustained a 99.9% ad-delivery success rate across 40+ event-driven microservices via end-to-end observability (OpenTelemetry, Prometheus, Loki) with sub-minute incident detection and event-order consistency.
• Shipped 6 fault-isolated ad-delivery services in 3 weeks for Phase 1, orchestrated over RabbitMQ and Kafka within the programmatic advertising platform.
• Integrated third-party SSPs for programmatic delivery — handling real-time bid responses and ad-exchange communication at high throughput.
• Engineered a shard-based real-time event system using Kafka partitioning and a Redis connection registry, streaming ad and recommendation events to clients via SSE.
• Designed a multi-database strategy (PostgreSQL, MongoDB, TimescaleDB, BigQuery with materialized views) matched to each workload, and led the production migration from BullMQ to RabbitMQ.
• Eliminated budget overruns with Redis-backed real-time spend tracking, pacing, and frequency-capping, plus forecasting and health-monitoring tooling.
• Built audio ad-serving pipelines (FFmpeg, HLS, TTS) and hardened the mobile SDK — code obfuscation (R8/ProGuard), secure request signing against tampering and replay, and size optimization across release builds.

Dubai, United Arab Emirates (On-site)

• Launched a car-rental platform (web + mobile) from zero to production, owning authentication, booking flows, and database architecture end to end (MySQL).

Remote

• Delivered full-stack web and mobile solutions for clients across backend and frontend.
• Heart Attack (fast-food brand, Egypt) — built the online ordering platform: REST APIs, authentication, and menu/ordering with a responsive frontend.
