Summary
Denis Lunev is a founder and seasoned software engineer with a decade of experience building high-load web systems and end-to-end payment platforms. He founded DepositFix, a B2B payments and billing automation company that integrates payments, invoicing, and A/R workflows into CRMs and QuickBooks to help mid-size businesses scale and collect faster. His background spans backend and frontend work at scale (Java, SOLR, Hive, MySQL/Postgres, JavaScript) and earlier startups/tools he built—including a time-zone comparison tool that was later acquired—showing both product instincts and hands-on execution. Denis has deep experience designing integrations and custom payment workflows, plus ISO partnerships to win card-not-present merchants, which reflects a strong mix of technical, product, and commercial skills. Based in Dallas, he brings entrepreneurial grit and a practical approach to solving billing complexity and cash-flow friction for growing businesses. Notably, he combines low-level system engineering experience with founder-level responsibility for go-to-market and partner relationships.
