▸ Developed a platform that leverages AI to automate data extraction and summarization of project bids, enabling subcontractors to set job preferences and general contractors to receive predictive insights on bid likelihood, reducing the typical month-long bidding process to under a week.

▸ Architected a pub/sub model using Redis to enable real-time communication between an AI-powered data extraction pipeline for scraped blueprint data and a user-company database, ensuring low-latency data synchronization and seamless platform responsiveness.

▸ Containerized a local database, cache, and API using Docker to ensure seamless portability and consistency across environments, enabling smooth deployment to an AWS EC2 instance and supporting scalable infrastructure.

▸ Designed and implemented a PostgreSQL database using Prisma ORM, leveraging the robustness of SQL for complex querying and relational integrity, while enhancing scalability and maintainability through efficient schema evolution.

▸ Developed a scalable API using NestJS and TypeScript, leveraging its modular architecture and built-in dependency injection, while ensuring type safety and maintainability through a strongly typed codebase.

▸ Integrated SendGrid API to automate email workflows and manage scheduled tasks with cron jobs, optimizing communication timing and improving user engagement through dynamic, data-driven emails.

▸ Established a Node.js/Express server with sessions, exposing a REST API built with routers and controllers to modularize the handling of network requests around a distinguished flow of data for testing and debugging.

▸ Architected a NoSQL database to store user listings and accounts, providing leeway for future scalability as well as adaptability for the necessity of a dynamic data schema to allow for seamless listing updates.

▸ Updated communications protocol with Socket.io and GraphQL subscriptions to introduce bidirectional data streaming, evolving a previously static user experience into one with real-time updates of reviews and posts.

▸ Leveraged Travis and Husky to continuously end-to-end test the codebase and update the EC2 instance with passed code on commits and pull requests, creating a streamlined CI/CD pipeline with consistent quality assurance measures.

▸ Bundled with Webpack to optimize speed and compatibility with ES6+ transpilation as well as minification and uglification to compress the build.

▸ Spearheaded & guided engineering teams through the lifecycle of open source product development, from ideation to deployment, while advocating Agile/Scrum methodologies & fostering technical growth for everyone involved.

▸ Championed a culture of excellence by conducting rigorous code reviews & interactive whiteboarding sessions with junior engineers, providing valuable feedback & upholding engineering best practices at every step.

▸ Evaluated potential candidates through meticulously designed technical & cultural interviews, precisely assessing coding proficiency, communication & debugging skills, & cultural alignment.

▸ Delivered enriching training seminars to groups of 30 engineers, empowering them with cutting-edge expertise in full-stack web technologies, including React, Node.js, TypeScript, Webpack/Docker, TDD, and API design, elevating their capabilities to new heights.

▸ Developed a configurable and distinct set of middleware for developers to throttle GraphQL queries and mutations through depth/complexity cost analysis, allowing for refined and accurate limiting based on several requests’ attributes.

▸ Tested and enacted a set of rate-limiting algorithms intended to run specifically alongside the middleware’s query cost analysis functionality while leveraging distinctions between each algorithm to allow users a multitude of throttling options and benchmarks best suited for their own APIs.

▸ Employed Test-Driven Development through unit testing (Jest) and integration testing (Supertest) to identify functionality required from each component, resulting in a simplified debugging process, organized documentation, and a strategic order of operations to streamline a more coherent codebase for future developers.

▸ Integrated Apollo middleware and GraphQL schemas into the developer portal’s Express framework to promote flexible CRUD functionality and facilitate dynamic API calling without the need for excessive endpoints or requests.

▸ Designed a developer portal with React/Chart.js to offer progressive visualizations of requested queries’ depth and complexity, providing clarity surrounding GraphQL query resolutions with reusable components and simplified cross-platform support.

▸ Product developed under tech accelerator OS Labs (opensourcelabs.io)
