Full stack engineers who cover both sides of the stack.

Your applications need developers who can move across the entire stack. Optis delivers full stack Java and JavaScript developers who know both sides and work as a team, not a collection of solo contractors.

Does this sound familiar?

1. You need developers who don't stop at the frontend or the backend.
Finding that combination consistently is harder than it should be.


2. Your current team is stretched across too many things.
‍
Good developers pulled in too many directions end up doing nothing well.

3. You're building something new and need the technical side figured out early.
‍
Architecture decisions made at the start have a long shelf life.

4. Your existing application has become hard to work with.
‍
Technical debt, unclear structure, outdated frameworks. Our developers will tell you honestly what needs to change and help you get there.

Why opt for Optis?

  • Our developers are comfortable on both sides of the stack. You can tell by how they talk about your architecture, not just the code they write.
  • No one figures things out on their own. Every Optis consultant has colleagues to check things with and learn from.
  • We've built platforms for large enterprises and fast-moving startups. The challenges are different.
  • We invest in our developers, so your team benefits from people who are always picking up new skills.
  • If a different approach would serve you better, we'll say so.

Two ways we can help

Full stack developers who integrate directly into your team. They work with your stack, adapt to your processes, and bring both frontend and backend skills to whatever your team is building.
‍
Every Optis consultant has the whole team behind them, so complex problems don't stay complex for long.
