Technical leadership.Hands‑on delivery.

I lead engineering organizations and stay close to the work—shaping architecture, writing code and building solutions that help teams simplify complexity and ship reliably.

Leadership grounded in engineering.

20+ years in software, 15 of them in leadership. My path moved from hands-on engineering into Engineering Manager, Head of Engineering, VP Engineering and Director roles across SaaS, blockchain, iGaming and eCommerce.

I focus on building strong engineering teams, improving delivery, simplifying complex systems and making pragmatic technical decisions that hold up against the business reality behind them.

Leadership is the main job, but I also build. I stay hands-on through architecture, code reviews, prototypes and production code when that helps the team understand constraints, test an idea or move a solution forward. Lately, AI-assisted development has made that part of the work even more effective.

Selected impact

Engineering organization30engineers

Led organizations of up to 30 engineers across multiple teams, including Engineering Managers and senior technical leaders.

Platform modernizationWeekly → daily

Led carve-out from a monolith to microservices, cutting release cycles from weekly to daily while improving reliability.

Payments+30%success rate

Led the reimplementation of a mission-critical payment routing system, increasing success rate by 30% in a high-throughput regulated environment.

Engineering effectiveness−30%cloud cost

Improved delivery lead time by 20%+ and led cloud optimization initiatives reducing infrastructure cost by ~30%.

How I work

01

Context over control

Give teams clarity on the problem and the room to own the solution.

02

Pragmatism over process

Use the lightest process that still creates clarity, quality and predictable delivery.

03

Technical depth without bottlenecks

Use architecture, code reviews and hands-on exploration to improve decisions, while engineers retain ownership.

04

Build systems and people

Organizations scale when both the platform and the people operating it can evolve.

05

Continuous improvement

Treat effectiveness, technical debt and org design as ongoing product problems.

Current focus

Updated

On-chain product tools

Wallets, DEX data, automation and infrastructure that make complex crypto workflows easier to understand and use.

Focused product experiments

Small mobile and micro-SaaS products that solve one problem well, ship quickly and have a clear path to sustainable operation.

AI-assisted engineering

Using AI as leverage in how software gets designed, reviewed and shipped. A practical part of the builder workflow, not a side experiment.

Engineering systems

Delivery effectiveness, developer productivity, platform architecture and the leadership practices that help each improve over time.

If you're scaling a team, improving delivery or simplifying a complex technical system, I'd be glad to compare notes.
