Bring your ideas
to life
Quantum Bytes is a one-person Canadian software studio. I design, build, and launch iOS and mobile apps, and partner with teams on custom web and backend work — from first prototype to App Store release.
Real products, publicly on the record.
No anonymised case studies — these are my own products, public and linkable, built the same way I build for clients.
Drift Focus
A focus timer that tracks intention and follow-through, not just minutes. Write what you'll do, run a session, then answer honestly.

A live situational picture of the Amazon basin: near-real-time deforestation alerts across nine countries, active fires, mining, and protected areas.

A one-person studio — the engineer you talk to is the one who designs, builds, and ships your product. No handoffs.
iOS & mobile apps
Native Swift / SwiftUI apps for iPhone and iPad — designed, built, and shipped to the App Store. I handle TestFlight, App Store review, and post-launch updates.
Custom software
Web apps, internal tools, APIs, and integrations. Modern stacks (TypeScript, Node, Postgres) and pragmatic delivery — small batches, real users, fast feedback.
Product & technical advisory
Architecture reviews, scoping, technical due diligence, and fractional CTO support for founders and product teams who need a senior perspective.
One senior engineer, no layers.
Quantum Bytes is Ronen Kalo — a senior software engineer who has been shipping iOS and web products for over a decade. Working with me means a direct line to the person writing the code, without the account managers and handoffs of a traditional agency. I take on a small number of projects at a time and ship them well.
I work with founders, growing teams, and established companies who care about craft. Most engagements run 4–12 weeks, with options for ongoing support after launch. My own apps — Drift Focus and Canopy Watch — are the public proof of how I build.
