06h 45m · −16° 43′ — Capabilities

A studio that takes products all the way to launch.

Most of the work is mobile and full-stack app development — designed, engineered, and shipped by one accountable builder, with no handoffs lost between people who never spoke to you.

01

iOS & mobile apps

Native and React Native apps built for the App Store — made to pass review, perform well, and feel native on the device.

02

Full-stack product builds

The whole stack under one roof: app, API, database, auth, and payments — wired together and deployed so the product actually runs.

03

Security-minded engineering

A background in security and compliance applied to real products — sensible data handling, integrity, and evidence built in from the start.

04

Idea to App Store

Provisioning, signing, store submission, and release infrastructure handled — the unglamorous parts that get a build into customers' hands.

Ship's log — Work

Products built and shipped.

Two entries that show the range — a consumer learning app live on the store, and a security tool engineered for integrity and compliance.

Live on the App Store

Cognivate

A study app built around grounded, source-labeled AI answers and spaced repetition — so what you learn is traceable and actually sticks. Designed, built, and launched end to end.

Sentinel Shield

A native iOS security tool that monitors traffic through a Network Extension and records activity to a tamper-evident, hash-chained ledger — turning device security into verifiable compliance evidence.

The approach

One hand on the wheel

Every project is scoped, designed, built, and shipped by the same person. Nothing gets lost in translation — the developer who reads your brief is the one who writes the code and submits the build.

The course — How engagements work

A clear heading, with your sign-off at every waypoint.

WP·01

Brief

You tell me what you need, A to Z. Scope, timeline, and cost are agreed in writing before any work begins.

WP·02

Draft

Work is delivered as drafts you can see and review — never a black box you wait on until the end.

WP·03

Iterate

You edit, comment, and send feedback. We refine together, round after round, until it's right.

WP·04

Launch

Nothing ships without your approval. Then it goes live, with the release details handled.

Charter & disclaimer

Sirius Financial Solutions provides custom software and app development services, conducted professionally and transparently. Every engagement is governed by a written agreement that defines scope, timeline, deliverables, and cost before work begins.

Project work is shared with the client as drafts throughout the engagement. Clients are encouraged to edit, review, and provide feedback across as many revision rounds as needed, so the final product meets their expectations. No deliverable is final until the client signs off.

The form below is a request for services only. Submitting it does not create a contract or guarantee availability; it begins a conversation about whether the project is a good fit.
