Fastest delivery, prioritized above everything else, for launches, fundraises, and hard deadlines.

Journey Rewards — Stepping In Mid-Flight

Joined as Head of Mobile to take over a cross-platform rewards app from the previous external team. Led 7 contractors across Android and iOS, built internal management from scratch, and gradually handed autonomy back to the engineers while delivering features on both platforms.

Challenge:
Replace an outgoing external mobile team mid-flight on a live KMM-based Android + iOS app, build internal mobile management from scratch, and keep shipping with zero loss of momentum.
Approach:
Audited the codebase before changing anything, kept the strong KMM architecture, retained two engineers from the prior team for continuity, and gradually moved engineers from routing-through-me to direct ownership.
Outcome:
Four-month engagement delivered features on both platforms, established an internal mobile management layer, and left a team that no longer depended on me to function.

Frequently Asked Questions

Who do you typically work with?

Four kinds of client, each with a dedicated page: VC funds (technical due diligence and portfolio engineering support), established companies adopting AI coding agents or auditing their architecture, teams of 100+ that need senior engineering capacity without a full-time hire, and distributed teams setting up async-first tooling. I work remotely, Europe-first, with scheduled syncs across timezones.

What services do you offer?

Fractional CTO and technical due diligence for funds, IT consulting (AI adoption and architecture audits) for established companies, embedded AI-leveraged engineering for larger teams, and async-environment setup for distributed teams. Underneath sit productized offers, retainers, Code Review, Scalable MVP Sprint, Lovable Rescue, each with its own page, scope, and intake form.

How do engagements start?

Most engagements start with a free 15-minute discovery call to confirm fit. If we move forward, you book the relevant intake form and a paid scoping call follows, ending with a written plan, a price, and a start date.

Do you write code or only set strategy?

Both. I review PRs, write production code, and pair with your developers. Pure strategy without execution is rarely useful in early-stage companies. The Advisor plan leans strategic; the Builder plan leans delivery; one-off services like Code Review and Scalable MVP Sprint are delivery-first.

How are you different from an agency or a generalist consultant?

You get one senior engineer with 12+ years of experience and 150M+ users impacted at Telegram and Recall, working directly on your codebase: no account managers, no hand-offs, no junior staff billed at senior rates. One accountable person who writes the code, reviews the PRs, and stays on the hook for the outcome.

How fast can you start?

Discovery calls are usually scheduled within a few business days of you reaching out. Once an engagement is agreed, retainer work starts the following week and fixed-price sprints (Scalable MVP, Lovable Rescue) start on the next available sprint slot. Active sprint capacity is listed on each service page.
