Hundreds of TypeScript projects delivered.
Our clients rely on us for TypeScript platforms that meet strict technical and business standards.
A healthcare provider aimed to connect millions of US veterans with their healthcare providers through a unified communications system. Our team of 35 senior engineers developed new automated channels, including an Interactive Voice Response (IVR) system and a WebChat tool. They also addressed over 1,000 issues to achieve WCAG accessibility certification and migrated the core database to a more secure PostgreSQL structure. This resulted in an 86% increase in patient interactions, reaching 4.9 million in a single year.
To improve the performance and reliability of its clinical trial platform, our client needed to reduce technical debt and modernize its architecture. Our engineers migrated their application to a serverless microservices architecture using AWS Lambda and updated the stack from JavaScript to TypeScript. They also developed critical new mobile app features, including detailed study tracking and a patient bulk upload tool. These enhancements increased software reliability and helped the platform enroll over 40,000 participants monthly.
A Fortune 500 insurance company needed to replace a high-maintenance legacy reporting tool and improve the reliability of its data systems. Our senior QA and Data Engineers were engaged to fix critical bugs, maintain complex ETL pipelines, and implement a modern Power BI reporting solution. The team delivered a successful Proof of Concept (PoC) for the migration and performed comprehensive QA to reduce defects, leading to more reliable data insights and reduced maintenance overhead.
The Typescript ecosystem we use:
We select stable, enterprise-proven tools that keep large codebases fast, observable, and easy to maintain. The stack favors explicit contracts, repeatable builds, and CI policies that prevent drift.
Languages and Core Frameworks
We standardize on long-term supported stacks and align with your version windows to reduce churn. This focus on stability ensures our software solutions are secure and maintainable.
Build, Bundling, and Transpilation
Builds must be fast, deterministic, and diffable in CI. We achieve this by keeping configurations minimal and caching aggressively, which directly improves developer productivity.
Monorepo and Package Strategy
Custom software development requires clear boundaries and safe publishing. Our approach uses tooling to codify ownership and automate versioning so multiple teams can work in parallel.
API Design, Contracts, and Validation
Contract-first delivery reduces integration risk. We generate types, validate at runtime, and enforce checks in CI, ensuring all parts of the system communicate reliably and predictably.
Data, Caching, and Messaging
Our tool choices for the data layer focus on type-safe, performant libraries for backend development. The selected caching and messaging systems are industry standards for high-throughput workloads.
Testing and Quality Gates
We front-load validation to ensure high code quality. The testing tools we use are modern, fast, and integrate fully into automated CI/CD pipelines.
Observability and Runtime Safety
Our stack for observability is chosen to ensure incidents are diagnosable in minutes. We standardize on OpenTelemetry for vendor-agnostic data collection and analysis.
Security and Dependency Health
We secure the software supply chain. The tools we use provide automated dependency scanning, policy enforcement, and artifact signing.
CI/CD and Environment Management
Our selected CI/CD and infrastructure tools are designed to make releases predictable and repeatable. We favor declarative, code-based tools that enforce all quality gates automatically.
We standardize on long-term supported stacks and align with your version windows to reduce churn. This focus on stability ensures our software solutions are secure and maintainable.

What tech leaders ask about TypeScript app development before pulling us in:
How senior are your TypeScript developers, and will we work directly with them?
Yes, you work directly with our engineers. When you hire TypeScript developers through us, you’re getting specialized professionals who average 10+ years of proven experience. Every team member is vetted through a rigorous evaluation process with hands-on technical tests and interviews focused on advanced TypeScript skills.
How quickly can we get started?
A typical kickoff happens in 2 to 4 weeks. Thanks to their years of experience (and often experience in your industry), our engineers ramp up fast and start contributing TypeScript code quickly.
Our teams plug into your existing TypeScript development workflows and collaboration tools for seamless collaboration, which also accelerates delivery.
Can your teams handle large monorepos without slowing releases?
Of course. Our TypeScript development services are specifically designed for large-scale enterprise solutions. We use monorepos with tools like Nx or Turborepo to manage complexity, which enables parallel workstreams and improves developer productivity. By enforcing strict CI checks and clear project boundaries, we consistently improve code quality and keep releases predictable.
Can you migrate a large JavaScript codebase to TypeScript without a freeze?
Absolutely. Our development team specializes in migrating JavaScript projects to TypeScript without halting your product roadmap. We plan incremental strictness and module-by-module adoption. Our dedicated teams add runtime guards and publish shared types. Delivery continues while defect rates drop and integration speeds up.
What does 'enterprise-grade' mean for your backend development?
Enterprise-grade means the software solution is reliable, observable, and secure. As a top software development company, we deliver custom TypeScript services that start with strong API contracts, instrument every service with OpenTelemetry, and apply performance best practices. These tailored solutions give you backends that are scalable, maintainable, and aligned with long-term business needs.
How do you approach performance in TypeScript applications?
Our development process starts with profiling hot paths, setting p95/p99 SLOs, and implementing full observability with OpenTelemetry. TypeScript enhances code quality by giving us typed contracts and predictable state, which makes it safer to optimize performance-critical areas without introducing regressions.
Combined with proven practices from other programming languages, this approach keeps your applications fast, scalable, and reliable in production.
What types of TypeScript projects have you worked on?
We’ve done just about everything in TypeScript web development. Our portfolio covers a diverse range of projects: front-end development with React and Angular, full-stack web applications with Node.js, single-page applications, and progressive web apps where offline performance was critical.
We’ve also built scalable web applications supporting millions of users, delivered custom applications for unique business needs, and modernized legacy platforms.
With extensive knowledge of the TypeScript ecosystem, we’ve created innovative solutions across industries. Whatever you’re building, chances are we’ve already done something similar and know how to deliver it reliably.
What does collaboration look like if we bring your engineers in?
We embed directly into your workflows, using the same tools and processes your teams already rely on. Our developers participate in your standups, sprint reviews, and planning sessions, so communication stays seamless.
We always surface progress and risks openly, and adapt to your architecture and security standards from day one. The result is a partnership that feels like one team working toward shared goals.
Can you support clients in regulated industries like finance or healthcare?
Yes, we have deep experience building solutions for regulated environments. Our development process is designed to meet the strict governance and audit requirements of standards like SOC 2 and HIPAA. We provide audit-ready software solutions by generating compliance artifacts like SBOMs, maintaining immutable change logs, and enforcing strict access controls.
