Dmitry Alexenko

Dmitry Alexenko is a Russian-American engineering leader and angel investor based in San Francisco (also Lisbon and Seattle). He serves as Head of Enterprise Engineering at Cloudflare (since September 2024), having joined from Stripe where he spent over four years leading billing infrastructure teams. He is active on X as @dalexeenko.^[1]

Career

Alexenko began his software career at Google as an engineering intern, then moved to Microsoft where he worked on Outlook and Windows features as a software engineer. He subsequently joined Airbnb as Engineering Manager of Managers for the Trust and Safety (anti-fraud) team, later becoming Engineering Manager in the risk organisation.

He then spent 4+ years at Stripe, serving as Head of Engineering for both Billing Infrastructure and Invoicing — roles in which he led significant advances in Stripe's billing systems and product growth. After Stripe he was Senior Director of Engineering at Checkr.

In September 2024 he joined Cloudflare as Head of Enterprise Engineering. In parallel he holds a role as Co-founder & CTO of Hazelcast Cloud. He describes himself as a "Cabernet Sauvignon angel investor."^[1] He holds a Master's degree in Computer Science from South Ural State University.^[2]

Stripeflare Project

During 2025, Alexenko was building an HTTP-level agent-friendly monetisation layer he referred to as "Stripeflare" — a project combining Cloudflare's infrastructure with Stripe-style payments for easy monetisation of Workers-based applications. He described three pillars: (1) easy monetised apps on Cloudflare, (2) HTTP-level monetisation layer for web publishers, (3) social payments. The project was pre-investor stage at the time, targeting early adopter traction first.^[3]

Separately, he was involved in Cloudflare's billing team work involving a 30+ engineer group focused on usage billing, with a sub-team led by a former Stripe engineer (Zunayed) building realtime per-worker billing infrastructure using ClickHouse/BigQuery.^[3]

Billable Usage Dashboard (April 2026)

On April 22, 2026, Alexenko shipped Cloudflare's new Billable Usage Dashboard — a cost breakdown tool enabling users to identify exactly which services are generating charges. He posted on X: "Why was I charged this amount? One of the most common billing support tickets we got. We shipped a new Billable Usage Dashboard..." Jan retweeted the announcement.^[4]

This directly addressed a pain point Jan had publicly surfaced on April 14, 2026, when he agreed with @levelsio that "there's no way to find which worker causes cost. having 100s of workers this becomes a mystery." The shipping of the dashboard — just eight days after Jan's complaint — closed a notable feedback loop between Jan's public Cloudflare commentary and the team's response.^[4]

Connection to Jan

Dmitry reached out to Jan directly on X following Jan's high-visibility Twitter activity in early 2025, making him one of the first notable inbound contacts from that period. Jan met him in Amsterdam in early September 2025 over coffee to discuss the Stripeflare project and a potential Cloudflare engineering role. Jan also asked Sunil Pai to introduce him to Dmitry as part of his Cloudflare network strategy.^[5][6]
