Awesome experience working with Alan and team. They are very experienced, straightforward and hard working.

[01] /services
What we take on. End to end.
One senior team from discovery to production. No handoffs to juniors, no offshore shop you never get to meet.
MVPs & new products
From a validated idea to production, scoped and shipped, not prototyped and abandoned.
SaaS platforms
Multi-tenant products built on a foundation that scales to 10x without a rewrite.
Web & mobile apps
Laravel and React on the web, React Native on mobile, one senior team across both.
AI in your product
Claude and OpenAI, RAG and agents, wired into real workflows, not a demo.
Security baseline and hardening
OWASP reviews, hardening and a production security baseline you can stand behind.
Fractional CTO
Architecture, hiring and the hard calls, embedded with your team for the long run.
Code and architecture review
A standalone review of an existing codebase. We find what will break, what is insecure and what slows the team down, and deliver a prioritised report.
Maintenance
We keep your app updated, monitored and patched after launch, with a few hours each month for fixes.
Accessibility and GDPR
We review and fix accessibility issues and GDPR compliance in existing apps.

You've been burned before. Not this time.
AGENCIES THAT DISAPPEAR AFTER LAUNCH
We stay after launch.
Most engagements become long-term retainers. Launch is the start of the relationship, not the end of the contract.
OFFSHORE TEAMS THAT NEED A TRANSLATOR
You talk to the engineers.
Porto-based, working US East Coast hours. You talk directly to the engineers who write your code. No project managers in between.
JUNIORS LEARNING ON YOUR PRODUCT
Senior engineers only.
You meet the people who will write the code before you sign anything.
Discovery
Scope, stack, milestones. We learn your business before writing code.
Architecture
Data models, APIs, infrastructure. A foundation that scales to 10x.
Build
Working software every week. Real deploys, real feedback.
Launch
QA, monitoring, deployment. We stay until it's solid.
Ownership
You own the code once it's paid.
[04] /founder
Senior people, real ownership, our name on it.
ALAN MAC CORMACK// from the founder
In more than ten years in tech I've watched founders get burned by teams that treated their product like a ticket queue. Obsidis is my answer: senior people, real ownership, and code we're proud to put our name on. If that's the team you've been looking for, I'd like to meet you.
