Node.js & NestJS development for WealthTech

Absolutely. Some of our projects start by extending or improving existing products rather than building everything from scratch.

We follow your architecture, coding standards, deployment process and development workflow, integrating as an extension of your engineering team from day one.

Both.

Some clients need one senior Node.js engineer to accelerate delivery, while others rely on us for end-to-end product development, including product strategy, UX/UI, frontend, backend, QA and DevOps.

We adapt to the stage of your company and your internal capabilities.

Yes.

Our team has worked on products including:

• Robo Advisors
• Broker API integrations
• Client Portals
• Advisor Dashboards
• Portfolio Reporting
• Proposal Builders
• Digital Onboarding
• Investment Platforms
• Employee Investment Benefits

Because of that, we already understand many of the workflows, stakeholders and challenges unique to financial products in WealthTech.

Absolutely.

We enjoy being involved early.

We regularly help clients challenge assumptions, prioritize features, simplify workflows and make product decisions before a single line of code is written.

Building the right product is just as important as building it right.

Yes.

These are some of the products we’ve been focusing on over the last few years.

We’ve worked on solutions involving portfolio reporting, advisor workflows, onboarding, proposal generation, internal operations and client-facing platforms for wealth management firms.

Financial software requires a different level of discipline.

We design systems with privacy, least-privilege access, auditability and secure development practices in mind. We also understand that every firm and startup has its own compliance requirements and we adapt our approach accordingly.

When using AI, we work with each client to define appropriate data handling policies and security boundaries.

Yes.

Whether your backend needs a Node.js version upgrade, a migration to NestJS, improved performance or a complete re-architecture, we can help modernize it incrementally without disrupting your business.

We believe maintainability is a product feature.

Our projects emphasize clean architecture, code reviews, automated testing where appropriate, documentation and scalable engineering practices that allow teams to move faster over time.

We’re based in Uruguay, giving us strong timezone overlap with North America.

Our team works daily with tools like ClickUp, Slack, GitHub, Jira, and Figma, integrating naturally into distributed engineering organizations.

Communication is part of the job, not an afterthought.

Because technology is only part of the equation.

Building products for wealth management requires understanding advisors, client relationships, reporting, onboarding, portfolio workflows, financial operations and regulatory constraints.

We combine that industry understanding with strong engineering capabilities, allowing us to contribute from day one instead of spending months learning your business.

Financial platforms are systems that handle a lot of integrations: custodians, market data, KYC providers, CRMs, etc. Node.js is well suited for this kind of work and it can handle many concurrent requests and API calls efficiently. In addition to this, leveraging TypeScript on both the frontend and backend lets them share the types and validations which translate to fewer integration bugs and better developer experience working across the stack.

We use NestJS, a TypeScript framework on top of Node.js, to build most backends. It facilitates a maintainable codebase as the scope and team grow because of its opinionated architecture (modules, dependency injection, guards, validations). We implement stateless APIs that scale horizontally, with caching, queues for background jobs and rate limiting.

Yes. Node has the ability to handle thousands of open connections with effectiveness, which makes it a natural fit for WebSockets and server-sent events. Some typical use cases are: live portfolio valuations, market data streams, alerts and transaction status updates.
