Hello!

I'm Danish Rehman, a Staff Software Engineer at Attentive, where I design and scale distributed systems and lead the architecture behind our AI-powered messaging platform.

I have 15 years of experience building high-throughput, fault-tolerant systems across AdTech and SaaS, with prior roles at Criteo, Yahoo, and Aspire, including multiple 0→1 platform efforts operating at 100K+ QPS and $100M+ ARR scale.

I enjoy mentoring engineers, driving cross-team technical initiatives, and speaking about distributed systems, most recently at Data Streaming Summit, P99 Conf, and Heapcon Conf.

Outside work, I bake sourdough breads and pizzas 🍞🍕, care for a backyard garden of citrus 🍊, berries 🍓, passionfruit 🥝, and guavas 🥭, and spend weekends biking 🚴‍♂️ and swimming 🏊‍♂️ with my son.
