Tech stack
  • Next
    Next.js is the full-stack React framework: it delivers high-performance web applications via hybrid rendering and powerful, Rust-based tooling.
    This is the React Framework for production: Next.js enables you to build full-stack web applications with zero configuration and maximum efficiency. It supports a hybrid rendering approach (Server-Side Rendering, Static Site Generation, and Incremental Static Regeneration) for optimal speed and SEO performance. Key features include React Server Components, Server Actions for running server code directly, and the App Router for advanced routing and nested layouts. Developed by Vercel, it leverages Rust-based tools like Turbopack and the Speedy Web Compiler for the fastest possible builds and a superior developer experience.
  • TypeScript
    TypeScript is an open-source superset of JavaScript: it adds static typing and compiles to clean, standards-based JavaScript.
    TypeScript is a high-level, open-source language developed by Microsoft: it acts as a superset of JavaScript, adding a powerful static type system. This system enables compile-time type checking, catching errors before runtime (a critical benefit for large-scale applications). The TypeScript Compiler (TSC) reliably transpiles all code into clean, standards-based JavaScript (ES3 or newer), ensuring compatibility across any browser or host environment (Node.js, React.js, etc.).
  • Stripe
    Stripe is the financial infrastructure platform for the internet, providing a comprehensive suite of APIs and tools for global payment processing and commerce.
    Stripe builds the economic infrastructure for the internet, offering a fully integrated platform for businesses (from new startups to enterprises like Amazon and Microsoft) to manage revenue operations. The core service is a powerful suite of APIs, allowing developers to embed payment processing natively into websites and mobile applications. Beyond accepting payments (online and in-person), the platform includes critical tools: Stripe Billing (for subscriptions/invoicing), Stripe Connect (for multi-party payments), and Stripe Radar (for advanced fraud prevention). This robust ecosystem facilitates global commerce, enabling companies to launch new business models and scale operations efficiently across 40+ countries.
  • Cron
    Cron is the Unix-like system daemon that automates scheduled command execution (jobs) via a time-based scheduler.
    Cron is your core utility for hands-off system maintenance: it executes commands or scripts at precise, recurring intervals. Jobs are defined in a configuration file, the `crontab`, which the `crond` daemon checks every minute. The schedule uses a five-field syntax—Minute, Hour, Day of Month, Month, Day of Week—like `0 2 * * *` for a daily script run at 2:00 AM. This tool is essential for tasks like log rotation, backups, and system monitoring, ensuring critical operations run reliably without manual intervention.
  • AI/ML
    AI/ML (Artificial Intelligence/Machine Learning) leverages algorithms—like deep neural networks—to instantly recognize complex patterns and drive predictive decision-making across massive datasets.
    AI/ML is the engine powering modern data utilization, fundamentally shifting how systems operate. Specifically, Machine Learning trains models (e.g., a 175-billion parameter GPT-3) on vast input data to execute tasks without explicit programming. This technology drives critical functions: natural language processing (NLP), computer vision (CV), and recommendation engines (Netflix, Amazon). Deployment results in significant operational efficiencies (up to 30% reduction in processing time) and unlocks new capabilities, transforming everything from drug discovery to automated logistics. We see this as core infrastructure, not just a feature set.
