What we build
Senior engineers build AI, cloud, security, and software systems from architecture through production.
Application Development
We build web and mobile products with the front ends and APIs your users need.
Full-stack Mobile Real-time
Cloud Architecture
We design AWS, Azure, and GCP infrastructure with IaC, deployment paths, and cost controls.
IaC Kubernetes Serverless
Platform Modernization
We move legacy systems onto APIs and services your team can change without a rewrite.
Replatforming API strategy Microservices
Security & Compliance
We review architecture, close compliance gaps, and prepare GDPR, HIPAA, and zero-trust programs.
Audits Zero trust Pen testing
Technical Leadership
We provide fractional CTO support, staff senior engineers, and evaluate technical bets.
Fractional CTO Augmentation Due diligence
Track record
Engineers on our team have shipped systems inside teams at Samsung, Microsoft, Verizon, T-Mobile, Toyota, Amazon, Walmart, and Fujifilm.
Where teams bring us in
Clients bring us in when they need to move AI or platform work from prototype to production, or when they need senior engineers to own an existing system.
Production AI
LLM features with evals and guardrails
We build LLM product features, retrieval, evals, guardrails, and observability around production workflows.
LLM features Retrieval Evals Observability
Platform rebuilds
Legacy systems your team can change
We move brittle paths into APIs, services, data pipelines, and cloud infrastructure while the business keeps running.
APIs Services Data pipelines Cloud infrastructure
Technical rescue
A path through stalled delivery
We join teams facing missed dates, fragile architecture, or unclear ownership, then turn the work into a plan engineers can ship.
Architecture review Delivery plan Team support Release path
Senior delivery
Senior engineers who own the work
We review architecture, plan releases, write production code, and stay close to operations.
Technical strategy Buildout Code review Operations
How we work
A small senior team, accountable from first scope to production.
-
Scope
We pressure-test the idea against today's model limits, then map the constraints and definition of done. We start coding once the team agrees on scope.
-
Architect
We design the system for where AI gets hard in production: evals, fallbacks, cost, latency. We solve those before they're load-bearing.
-
Build
Senior engineers build in your stack, alongside your team, and ship to production in short iterations you can see week over week.
-
Operate
We harden it, write the evals and docs your team will use, and hand over real ownership. After that, we stay on call.
Why partner with Lusona LLC?
Engineers and architects founded Lusona LLC after building production systems for Fortune 500 companies and high-growth startups. We bring that experience to architecture reviews, buildouts, handoffs, and production support.
We stay close to the code. Senior engineers design the system, write the critical paths, review the work, and leave your team with docs, evals, runbooks, and ownership it can keep.
01
Production discipline
We write the tests, evals, docs, and runbooks production systems need.
02
Right tool, not the trend
We choose models, frameworks, and cloud services for the constraint in front of us.
03
Senior ownership
Senior engineers design, build, review, and ship with your team.
04
Clear handoff
Your team leaves with code, context, and operating paths it can own.
Global reach
We support teams across North America, Europe, and Asia-Pacific with distributed delivery and support.
