About Fidelis Soft

Built by
builders.

We're an IT consulting company made of senior engineers who got tired of the hourly-billing, resume-sorting, out-of-context staffing model. So we built something closer to what our clients actually want: teams that feel like their teams, embedded, flat-fee, and AI-fluent from day one.
How we work
01 · Principle

Senior or don't send.

Every engineer we place has at least 6 years of production experience. We don't pad teams with juniors to hit margin targets.

02 · Principle

Flat fee, no surprises.

A monthly rate per team member. No timesheets, no scope-creep invoices, no employment taxes on your books.

03 · Principle

AI is a tool, not a pitch.

We use LLMs in our daily work — for review, planning, docs — and we teach your team to do the same. The output is faster humans, not synthetic ones.

04 · Principle

Write it down.

Decisions in docs. Architecture in diagrams. Handoffs in checklists. If it only lives in Slack, it doesn't exist.

05 · Principle

Calm production.

We ship on Fridays because our pipelines, alerts and rollback paths let us. Boring infra is a feature.

06 · Principle

Leave your team better.

The goal of every engagement is that your team can run it without us. We're measurably not trying to become indispensable.
