About Enyel Leonardo
Full-Stack Developer | React, Next.js & .NET | SaaS and Fintech Apps
Santo Domingo Oeste, Dominican Republic - 10:11 pm local time
That means I'm used to code where correctness actually matters: financial calculations that have to reconcile, reports that go to a government regulator, and systems that can't quietly fail. I bring that same standard to smaller projects.
What I can build for you
• Full-stack web apps with React, Next.js and TypeScript. Dashboards, admin panels, internal tools, client portals
• Multi-tenant SaaS platforms with role-based permissions, authentication, and proper data isolation between clients
• REST APIs and backends in .NET / C# or Node.js, with clean, layered architecture that stays maintainable
• Database design and optimization in PostgreSQL, SQL Server and MySQL including fixing slow queries and broken reporting logic
• Point-of-sale, inventory and ERP systems, including invoicing and tax compliance features
• Third-party API and payment/messaging integrations, including webhooks and status tracking
Recent work
• Designed and built a multi-tenant SaaS ERP for a retail and repair business inventory, point of sale with mixed payments, repair workflow, daily cash reconciliation, and tax-compliant invoicing. Built to scale to new clients without touching the codebase.
• Develop and maintain enterprise banking applications and regulatory reporting systems REST APIs in .NET with Entity Framework Core over PostgreSQL, plus React dashboards for data visualization.
• Audited and fixed regulatory reports in SQL Server, tracking down inconsistencies in classification logic, currency conversion and calculations that others had missed.
• Built a complete POS system end to end React frontend with an interactive metrics dashboard, and a Node.js/Express REST API with JWT auth and centralized error handling.

How I work
I ask questions before I start building, because most wasted development time comes from assumptions nobody checked. I communicate clearly in English and Spanish, give you honest timelines instead of optimistic ones, and tell you early if something isn't going to work.
Send me a message with what you're trying to build and I'll tell you straight whether I'm the right fit.
