Building from Stockholm — @mask1no

I turn ideas into web apps
that ship.

I design and build focused products end-to-end: sharp interfaces, practical AI, reliable backends, and launch-ready deployment.

Now — July 2026
potwise.xyz

A private card-decision workspace for poker equity, pot odds, blackjack checks, and study notes.

copycodes.xyz

A searchable promo-code intelligence site with verification labels, offer context, and claim paths.

Selected work

02 / 07

Two live products that show the range: one private decision workspace, one public SEO-focused offer engine.

Potwise

A decision workspace for players who want pot odds, equity thinking, blackjack checks, and notes in one calm interface.

Problem
Card tools are usually split between calculators, note apps, and messy lookup tables.
Outcome
Potwise combines the study loop into one focused product with a cleaner decision surface.
Private-first flowFast hand contextStudy notes

Built around fast inputs, private study flow, and clear action guidance instead of noisy gambling dashboards.

Vault

05 / 07 · put aside

Projects I started, learned from, then put to the side. The line through the names is intentional: these are vault items, not active launches.

Keymaker

2025

Solana bundling toolkit built around Jito flows for packaging launch transactions, coordinating wallet execution, and reducing failed or exposed moves during high-pressure entries.

put aside while the market and tooling changed.

Silk Swap

2024

Anonymous crypto swapping experience with a dark Silk Road-inspired interface, focused on privacy-first routing, clean swap intent, and a memorable product theme.

shelved before turning the concept into a public product.

Running Raccoon

2025

Wallet intelligence dashboard for watching selected wallets, following transaction patterns, and getting alerts when bundlers, coordinated wallets, or likely rug-pull actors move.

paused while higher-priority builds took over.

How I work

06 / 07
01

Web applications

Production-grade web apps with modern stacks, polished UI, reliable flows, and enough structure to keep shipping after launch.

02

AI integration

Practical AI implementations across chat, content, voice, automation, and model workflows without forcing AI where it does not help.

03

Rapid prototyping

Fast prototypes that test the real product idea early, using AI-assisted development to move quickly without losing clarity.

04

Design systems

Interface systems with reusable components, consistent states, and enough design discipline to make the product feel intentional.

Process
01

Discovery

Understand the problem, define the outcome, and decide what is worth building first.

02

Design

Shape the interface, flows, and product feel before the build starts moving fast.

03

Build

Turn the plan into working software with tight feedback loops and visible progress.

04

Feedback

Review the product in use, catch rough edges, and adjust before they become expensive.

05

Iterate

Refine the details, improve the flow, and keep the product aligned with real usage.

06

Deploy and Ship

Launch with the right hosting, checks, and handoff so the build can keep running.
