Lance Owen Gulinao

Fullstack Web Developer,


👋 I'm Lance, a third year computer science student studying in UST. I develop websites that provide value to other people. I constantly refine my skills and workflow by experimenting with new tech and tools.

In my free time, I automate tedious processes that block creative output and tinker with programming language design.

Some of the pages I brought to life

Problems faced and solutions system design writeup here

Short development time (April 18 - June 19)

  • Creating a custom backend framework that allowed for rapid feature development and integration between backend and frontend.
  • Implementing continous integration and testing with GitHub actions for constant QA.
  • Developing reusable components for the public and admin side of the website, with the help of SCSS mixins.

Lack of existing code libraries for common tasks

Developed copy and paste code snippets that can be used in future projects

  • Lack of full text search support for Prisma + SQLite
    • Gandalf - A function for describing and manipulating bitfields with full typesafety.
      • Used to implement role based user authentication with permissions.
    • RuntimeEnum - A function for creating enums which can be validated at runtime using Zod.
      • Used to store enum strings in databases that don't support enum values.
    • Scheduler.ts - A basic task scheduler built on top of node-schedule.
      • Used to release scheduled posts in the content management system.
    • Paginator - A react hook generator for dealing with paginated data from the backend.

    Reconciling content from an existing repository

    • Automated migration of content from old sources using Google Sheets

    An experimental library for building fullstack typesafe REST and WebSocket APIs with TypeScript

    • Improves developer experience by reducing type-related code errors.
    • Used in production by
    • Generates a typesafe client-side RPC library from server-side code automatically.
    • Allows developers to easily create realtime apps with typesafe event-based WebSocket connections.


    A lightweight express wrapper offering a typesafe middleware experience

    • Increases quality-of-life by automatically loading express.json(), cookie-parser, morgan, cors, and handling errors and rejected promises.
    • Provides middleware type information to API resolvers using TypeScript generics.
    • Simplifies common tasks such as multipart form uploads and authentication.
    • First class WebSocket support, treating WebSockets as if it was another HTTP method.


    A tiny library for creating typesafe layouts with Next.js Pages Router

    • Fully customizable, guarantees the types of different data flows between layouts and pages.
    • Handles the automatic caching and revalidation of page props.


    A library for defining GraphQL resolvers and schemas using the Zod validation library

    • Uses a declarative, code-first approach for defining resolvers.
    • Usable with any API framework and can even be queried directly without an API.


    A volatile in-memory data store for JavaScript applications

    • Fully typed with TypeScript and tested with Jest.
