Alex Lunin

Since 2010 I've been building other companies' products end-to-end. This past year, I built my own, solo — that's Atlano.

Since 2010 I've been building web, mobile and infrastructure for companies like Vereign (Switzerland), Mozio (USA) and Mobilabsolutions (Germany). Most recently, shipping my own products solo — product, code and infra, end to end.

Proof of work Shipped: v2.8.1 · closed beta

Atlano

A habit, goal, balance-wheel and journaling app I build and ship solo — end-to-end.

Solo: product, design and all three codebases — mobile, web and API — plus database, billing and ops.

Problem

Habit apps count streaks but ignore whether your life is actually in balance — and most fall over the moment you go offline.

Approach

Offline-first and multi-surface: a React Native app with a local SQLite mirror, a web app, and a Hono / Postgres API sharing one typed core.

Outcome

Shipped to v2.8.1 with 2FA and multi-currency billing live — a life-balance wheel, day planner and journal on top of a real offline sync engine.

The hard parts

▸ State-based delta sync with a per-user monotonic revision watermark — replaced an unbounded append-only changelog.
▸ Soft-delete tombstone propagation and whole-row version-OCC conflict resolution.
▸ A monorepo spanning 3 apps + 1 shared package, typed end-to-end from database to UI.

This is what solo, end-to-end delivery looks like. If you need the same, let's talk.

Experience

Apr 2025 — present · ~1 year · Remote

Independent — Founder & Product Engineer

Roughly forty builds solo since April 2025 — three I'd defend in detail.

Product, code, infra, ops and billing — using AI-assisted workflows to compress build time while owning every architecture and review decision myself. Production: Atlano (habit, goal & life-balance app — see above), Millionaire Habits (AI-driven analysis of 250 billionaires).

Oct 2018 — Apr 2025 · ~6.5 years · Remote

Vereign AG — Switzerland

Owned mobile end-to-end on a Zero-Trust authentic-communication platform.

React Native + Expo apps shipped to the App Store and Google Play. Built the Personal Data Wallet UI on Credo-TS, the Outlook plugin (Microsoft AppSource) and a Chrome extension. Contributed to a Swiss healthcare Zero-Trust project (IPFS, self-signed cert identity) on the frontend/integration side. Upstreamed fixes to Credo-TS.

Mar 2017 — May 2018 · ~1 year · Remote

Mobilabsolutions — Germany

Kept a complex production app at 80%+ test coverage.

Frontend on a complex web app against a Python micro-service backend.

Mar 2016 — Mar 2017 · ~1 year · Remote

Mozio — USA

Worked on a live AngularJS → React migration in production.

Migrated page-by-page in production, with both stacks running side by side. Built new components and post-migration features.

Dec 2010 — Dec 2015 · 5 years · Ulyanovsk, Russia

SimbirSoft

Junior to senior in 3 years, across 30+ projects.

Very different stacks (JS, AngularJS, C#, Java, PHP, Ruby on Rails, desktop). Frequently rotated onto troubled projects to stabilize delivery.

Selected projects

Sidewire — second Mac as a display ↗

Solo: design, native app, Rust client, landing, release tooling

Turns a spare Mac into a real extra display over Thunderbolt or Wi-Fi — a virtual display captured and streamed with hardware HEVC, keyboard and mouse forwarded across machines. Source is open, including the honest list of what is left before release.

About

Senior full-stack engineer, in software since 2010 — I started at SimbirSoft straight after a non-IT degree, and have spent most of the last decade working remotely with clients across the US, Germany, Switzerland and beyond.

The deepest of those years — six and a half — went into Vereign's Zero-Trust platform in Switzerland; the details are in Experience and Projects below.

After Vereign, I took a year to build for myself instead of a client — Atlano is the result, and the same AI-assisted workflow that shipped it (see "How I work" below) is what I bring to a team.

How I work

▹

End-to-end ownership

I can take a product from idea to production solo — frontend, backend, mobile, infra and release.
▹

Comfortable in unknown stacks

At SimbirSoft I was the engineer rotated onto troubled projects — ramp on a new stack within weeks and stabilize delivery.
▹

Judgment first, AI second

AI compresses the typing, not the judgment — every architectural call and every line that ships is mine to defend, the same review discipline regardless of who or what drafted it. It's the same discipline behind Atlano's sync engine above.
▹

Direct communication

No agency, no middlemen — you talk to the engineer who writes the code.

What I can build for you

Services I take on for startups, SMBs and international remote teams.

MVP for startups

Fast, focused builds to get an early-stage product in front of real users.

Mobile apps

React Native + Expo, shipped to the App Store and Google Play.

Web apps

React, Next.js, Astro — from marketing sites to full product frontends.

Backend & infra

Node.js, Go, C#, PostgreSQL, Docker/Kubernetes, CI/CD.

Telegram bots & web apps

Bots, mini-apps and business integrations on the Telegram platform.

Technical consulting

Architecture reviews, stack decisions, and getting an unfamiliar codebase back under control.

Ongoing support

Maintenance and continued development after launch.

Let's talk

Open to long-term remote roles and contracts. I respond within 24 hours.

6.5 years building Zero-Trust systems at Vereign (Switzerland). Contributor to Credo-TS under the OpenWallet Foundation.
