Olga Topchaya

Founder, CEO
Lapis AI Consults

I help SMBs innovate with AI. I transitioned into the AI domain after a decade-long, vibrant journey in diverse marketing roles. My career has been centered on working with startups and SMBs so I am intimately attuned to the unique needs of these companies, which is what inspired me to launch Lapis.

I balance the exhilarating world of AI innovation with the equally rewarding role of being a new(ish) first-time parent. While both realms are vastly different, they share a common thread: the need for adaptability, quick learning, and contextual understanding. Lapis is not just a consultancy; it's a philosophy that embodies adaptability and forward-thinking, characteristics I've found essential in both parenthood and AI innovation.

I currently work at Vitrifi, where I share their vision of creating innovative solutions that empower people and businesses.

At Vitrifi, I am part of the team that builds modern APIs and microservices using Go and GraphQL, following the best practices of design, testing, and documentation. I also use React to create responsive and interactive web interfaces that enhance the user experience and engagement. I enjoy working with a talented and diverse team, where I can learn from others, share my ideas, and deliver high-quality products.
