About LEON TECH
A small team of senior engineers, treating your product like our own.
We work with founders and product leaders who care about the long arc — not the demo. Our work is grounded in clean architecture, sensible abstractions, and a respect for the systems that real users depend on.

Services
What we build, end to end.
A focused set of capabilities — applied with care to the problem in front of us.
SaaS Product Development
End-to-end engineering for multi-tenant platforms, from data model to billing.
Custom Web Applications
Type-safe, performant web apps with thoughtful UX and clean engineering.
AI-Powered Software
RAG, agents, and ML workflows integrated into real product surfaces.
MVP Development
Ship a credible v1 in weeks — without the technical debt that costs you v2.
Cloud Architecture
Pragmatic infrastructure on AWS, GCP and Azure — provisioned with code.
API Development & Integrations
REST, GraphQL and event-driven APIs designed to be extended, not rewritten.
UI/UX Product Design
Interfaces that feel inevitable — informed by behavior, not just aesthetics.
Scaling & Optimization
Profile, refactor, and harden — for the load your product will actually face.
Maintenance & Support
Continuous engineering: observability, on-call response, and quarterly upgrades.
Process
How we move from idea to scale.
A predictable cadence — designed to keep risk low and momentum high.
01
Discovery & Strategy
We map the problem space, success metrics, and constraints — before a single line of code.
02
Product Architecture
Data models, system boundaries, integrations and infrastructure designed for a 24-month horizon.
03
UI/UX Design
Flows and interfaces validated against real workflows, not just design tokens.
04
Agile Development
Two-week iterations, demoable each Friday, with continuous deployment from day one.
05
QA & Testing
Type-safety, integration tests, load tests and security checks built into the pipeline.
06
Deployment & Scaling
Observability, autoscaling and runbooks — so growth never becomes a fire drill.
Featured platform
Northbeam — a multi-tenant operations platform for B2B services.
We led architecture and delivery for an internal-tool turned commercial SaaS: role-based access, automated workflows, billing, and a real-time analytics layer — running on a CI/CD pipeline that ships dozens of times per week.
- Multi-tenant data isolation with row-level security
- Workflow engine handling 9M+ events / day
- Role and permission model spanning 12 entity types
- Self-serve billing with metered usage and invoicing
