TypeScript development
TypeScript turns sprawling JavaScript codebases into navigable, refactorable systems. We write it end-to-end, from database schema to UI props, so whole classes of bugs never reach production.
In short
TypeScript, at a glance
- Null errors, wrong shapes and bad calls die in CI instead of production.
- Rename, restructure and upgrade with the compiler verifying every usage.
- Types are documentation that can't go stale, so onboarding gets dramatically faster.
- Autocomplete, inline docs and safe automated edits in every editor.
Why TypeScript
TypeScript in production.
TypeScript adds a static type system on top of JavaScript: the compiler reads your code's intent and flags contradictions before anything runs. At team scale, that's the difference between confident refactors and fearful ones.
We use strict-mode TypeScript across frontend and backend, with types generated from the database and API schemas. One source of truth flows through the entire stack.
Bugs caught at compile time
Null errors, wrong shapes and bad calls die in CI instead of production.
Fearless refactoring
Rename, restructure and upgrade with the compiler verifying every usage.
Self-documenting code
Types are documentation that can't go stale, so onboarding gets dramatically faster.
Superb tooling
Autocomplete, inline docs and safe automated edits in every editor.
Scales with the team
Contracts between modules and teams are enforced, not hoped for.
Industry standard
The default for serious JavaScript, and most-loved and most-used in surveys for years.
How we engineer
with TypeScript.
How we work
Senior engineers, accountable to outcomes. Every change typed, reviewed and tested.
01Greenfield TypeScript builds
Full-stack products in strict TypeScript with shared types across every layer.

View case studyA six-step cycle, repeated until it's right.
Transparent, predictable and collaborative. You always know what's shipping next and why.
Discovery
We map the business, users and constraints, then pressure-test the problem before a line of code.
Planning
Architecture, scope, and a sprint roadmap with clear milestones, budgets and success metrics.
Design
Research-led UX and high-fidelity interfaces, validated with prototypes before build.
Development
Senior-led engineering in two-week sprints with demoable increments and continuous review.
Testing & QA
Automated and manual testing, security review and performance hardening before release.
Launch & Care
Confident deployment, monitoring and SLA-backed support that keeps things humming.
TypeScript questions, answered.
Still unsure if TypeScript is right for your project? A senior engineer will tell you straight on a free call.
For anything beyond a prototype, yes. The compile-time safety pays for itself in fewer production bugs, faster onboarding and refactors that would be terrifying in plain JavaScript.
Yes, incrementally. TypeScript coexists with JavaScript file-by-file, so we type the riskiest modules first and ratchet strictness up over time without stopping feature work.
It front-loads a little thinking and removes a lot of debugging. Teams consistently report faster delivery once shared types eliminate integration guesswork.
One schema, usually the database, generates types that flow through the API layer into UI components. Change a column and every affected line of frontend code lights up before deploy.
Yes. Without strict null checks and no-implicit-any, TypeScript is mostly decoration. We configure strictness appropriate to the codebase and ratchet it upward safely.
