Product Engineer · Consultant · Coach
Let's build something lasting.
I help product teams and dev studios cover full-stack gaps — backend, frontend, or mobile — turning technical plans into systems that hold up under real traffic, without the lead time of a new hire.

How I can help
Two ways to work together — one for shipping, one for levelling up the people who ship.
Full-stack capacity on demand
Senior backend, frontend, or React Native capacity that slots into your team for a project, a sprint, or the gap between hires — no recruiting lead time, no ramp-up drag.
- Java/Spring Boot, React/Next.js, or React Native — whichever the project needs
- Plugs into your existing codebase, tools, and workflow
- Scoped and billed for the engagement, not a long-term retainer
Team mentoring & code reviews
Pair programming, async reviews, and coaching that raises the floor of what your team ships — without slowing the roadmap down.
- Clean Code, TDD, and system design coaching
- Async PR reviews with written rationale
- Architecture sounding board for engineering leads
How I work
The same three things show up in every engagement, whether it's a two-week sprint or a six-month rebuild.
Structure without red tape
Lean process, visible progress, and decisions written down where the team can find them. No ceremony for its own sake.
Strong ownership
I work independently and integrate into remote teams without hand-holding. You get a contributor, not a ticket-taker.
Clear communication
Technical depth that survives translation to stakeholders. If I can't explain the trade-off, it isn't the right trade-off yet.
Products I've built
Three apps I designed, built, and took to market on my own — end to end, from first line of code to App Store listing.
23Brain
Your AI-powered second brain
Turns saved articles, videos, and notes into structured summaries, quizzes, and semantic search — so what you read actually sticks. Freemium subscription app with a free tier and two paid plans.
The work: Designed and built the mobile app, backend, and subscription billing solo, then ran the launch marketing on TikTok and Instagram and set up the App Store and Play Store listings.
Smaipa
An AI assistant that lives in WhatsApp
Replaces five separate productivity apps — reminders, contacts, scheduling, email, task lists — with one WhatsApp chat. Nothing new to install or learn, just a message.
The work: Built the product solo from idea to launch, including the WhatsApp integration and AI assistant logic, and ran the marketing and positioning myself.
Chips Story
The poker chip counting API
Send a photo of stacked poker chips, get back the count, per-stack breakdown, and total value as structured JSON — built for casinos, tournament organisers, and streamers, with a companion app for players.
The work: Built the computer-vision API, developer docs and portal, and the companion mobile app, including the metering and usage dashboard.
Let's work together
Whether you need an extra pair of experienced hands or a technical sounding board, the first conversation is free and there's no pitch attached.
