Summary
👤
Senior🎓
Top SchoolAaron Cassar is a founding engineer and full-stack developer based in New York with eight years of experience building web, AI, and systems-focused products for startups. He has repeatedly joined early-stage teams—both as founder and founding engineer—helping YC-backed companies like Ekho and Vendora deliver scalable payments, catalog, and frontend design systems. His work blends backend reliability (data pipelines, entity resolution, catalog infrastructure) with production-ready UX, turning messy data into normalized models that support growth. Aaron also has entrepreneurial instincts, founding Wanderer's Guide and helping shape multiple products end-to-end, which gives him a product-minded engineering perspective. Colleagues would note he prefers solving ambiguous problems—designing canonical systems where none existed—rather than incremental feature work.
