Alex Lunin

16 years building other companies' products end-to-end. This past year, I built my own, solo — that's Atlano.

16+ years 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.

About

Senior full-stack engineer with 16+ years of commercial experience — 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.
