Tomass Lacis · Independent Systems & Platform Architect

Complex systems.
Clear solutions.

I help companies put AI to work in their engineering, and architect, modernize and scale the backend platforms, distributed systems and cloud infrastructure underneath it.

Problems I solve

Make better technical decisions.
Build systems that last.

AI is a demo, not a workflow

Your team experiments with AI, but it never reaches the repos, tickets and operations where the work actually happens.

The platform is fighting you

Deploys are slow and scary, environments drift, and every change needs a hero.

Costs grow faster than usage

Cloud bills and operational overhead climb while nobody can say which part of the architecture is to blame.

Scale is starting to hurt

Telemetry, devices or data volumes outgrew the MVP design, and reliability is slipping.

Big decisions, no architect

You need senior judgment on a design, vendor or migration, without hiring a full-time architect.

Hardware meets cloud

Device identity, provisioning and fleet management need to be production-grade, not a shared API key.

How I work

Assess → Design → Build → Measure

  1. 01

    Assess

    Understand the system, the team and the constraints. Find the expensive problems first.

  2. 02

    Design

    Make the key decisions explicit, with trade-offs, costs and a realistic roadmap.

  3. 03

    Build or guide

    Implement the hard parts hands-on, or steer your team through them.

  4. 04

    Measure

    Agree on what better looks like, then prove it with numbers.

Engagements are either a scoped project with clear deliverables, or fractional advisory a few days a month. A good first step is a fixed-scope Architecture & Platform Health Check.

Have a difficult technical problem?

Tell me what you're building, what's not working, or which decisions you're trying to make. I usually reply within two working days.
