Mohammed Masry — Product AI Engineer

Software & Product AI Engineer with 5+ years designing, shipping, and operating scalable event-driven systems and AI-powered products. Led a programmatic advertising platform of 40+ microservices to a sustained 99.9% delivery success rate through fault-tolerant design and end-to-end observability. Equally comfortable in backend, full-stack, and mobile, and at translating messy, real-world requirements into reliable systems deployed directly alongside users.

Product AI Engineer, Heru Loop (Jun 2026 – Present)

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.

Software Engineer, InTouch.com (Jul 2023 – Jun 2026)

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.

Software Engineer, Rentop.co (Feb 2022 – May 2023)

Dubai, United Arab Emirates (On-site)
