Professional Experience

Engineering Manager & Sr. Full Stack Engineer / 2022 – Present

Glassnode · digital asset market intelligence · Remote (Berlin, Copenhagen, Barcelona, Prague)

As an engineering manager, I've consecutively led three engineering teams (mobile, a greenfield portfolio product, then Studio), up to 12 engineers at peak and two teams at once for a period. That meant coaching, setting engineering strategy, and holding the bar on engineering practices, while staying hands on across frontend, backend, and BI (anywhere from 20% to 80% of my time, depending on the needs of the team). I worked on introducing an empowered engineering culture on a new full-stack team, with trunk-based development and small, continuously shipped changes. Later, we spread the model more broadly, and I kept optimizing teams to ship faster and more reliably.

My teams at Glassnode owned the Studio, data visualization, information architecture, billing, public APIs access, permissions, payments, and content pages. Few highlights out of many. A server-side-rendering migration that more than halved the homepage load time and enabled new products (e.g. Market Compass) to be released in a single day. A homepage rebuild that got ~6x more visitors into the product (from 5% to 31% of arrivals). An in-house AI agent platform that lets non-technical people safely ship to production with zero side effects (limited access & robust harness). More projects: global search, payments migrations, performance and UX improvements, internal AI tooling and external AI chat, direct customer eng. support, etc.

Currently, I'm designing Studio's information-architecture overhaul end-to-end, from concept and user-feedback sessions through to the final solution.

Sr. Full Stack Engineer to Engineering Manager / 2017 – 2022

Bitwala / Nuri · fintech, digital banking & investing · Berlin & Remote (Montreal)

Bitwala offered a German bank account with the possibility of investing in crypto and using your crypto with ease. I built the native apps (Android & iOS) and web client from scratch shortly after joining, which set the foundation for the entire product. From there, I grew alongside the company as it scaled to over 200,000 customers.

My responsibilities over time included releasing the native apps to the app stores, overseeing production releases across all components, and maintaining banking-related AWS services. Later, I managed the neobank team working on the banking side of the product.

Tech lead of company-wide projects, e.g. Bitwala to Nuri rebranding (managed 6 people across 3 teams), learning section within the app, standing orders, scheduled investments, etc.
