Email: saad99u@gmail.com Hi, I am Saad! Senior product engineer, 5+ years at early-stage product startups (Series A B2B marketplace and fintech, ~80 engineers). Joined as a junior and earned 4 promotions in 2.5 years. Cut AWS costs 84% ($6.4K to $1K/mo). Shipped a production agentic AI procurement system that autonomously discovers suppliers and negotiates at zero headcount. Scaled REST APIs from 3.5K to 21K concurrent users with 89% latency improvement. Architected a cross-border multi-currency system with FX-rate-aware transactions. Led a 4-engineer team delivering 6 revenue-critical features. Built a shared Node.js SDK adopted across 7+ services cutting setup time by 70%. Also built fintech integrations. Looking for a founding/senior engineer role where ownership, velocity, and keeping burn low actually matter. Linkedin/Github is hyperlinked in the resume. Thanks!
