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

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. A project manager keeps things on schedule, and you still talk directly to the engineers writing your code.
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.

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.
