Summary
👤
Senior🎓
Top SchoolJames Kessler is a technology executive and operator with 25 years of startup experience and a 13-year track record of hands-on engineering and leadership. As COO of Coveralls.io he combines product and engineering stewardship to deliver test-coverage-as-a-service while previously scaling technical organizations as CTO and Director of Technology across retail and consumer brands. He has founded and led multiple ventures—building inventory and fit-search systems, running offshore engineering teams, and serving as a fractional CTO for fast-growing merchants—so he bridges strategy, product discovery, and execution. Known for turning ambiguous product needs into delivery roadmaps, he routinely aligns engineering squads to business outcomes for companies ranging from early-stage startups to Fortune 500 clients. Based in Los Angeles, he pairs practical full-stack experience (Ruby on Rails, Java, web stacks) with a founder’s appetite for product-market fit. A less obvious strength is his long history of operating both technical delivery and commercial-facing roles, giving him fluency in engineering, sales enablement, and partnerships.
