Experience

I started programming in senior high school in mid-2018, so I’ve been programming for almost six years now. In college, I spent a lot of time trying to start my own business instead of fully focusing on my studies, only focusing later during thesis. While those attempts didn’t work out, they taught me a lot about problem-solving, persistence, and thinking creatively. These experiences helped me become a much more confident programmer.

As for work experience, I’ve interned at Infor and Flowerstore.ph, where I worked as a QA. This helped me build strong attention to detail and gave me a better understanding of how software development works from an industry perspective.

I’ve also done some pentesting on platforms like HackerOne, Bugcrowd, and Intigriti. During this time, I found bugs in notable companies such as Shopify, PayPal, GitHub, Twitter, Coinbase, Airtable, HackerOne, and Google (the latter through an external bug bounty). These experiences sharpened my analytical skills, attention to detail, and ability to think like an attacker, which I’ve been able to use in building better, more secure systems.

Frontend

I have 4 years of experience in frontend development, but my earliest memory of working on frontend dates back over 8 years to designing UIs for mobile games. On the web, I started with React and advanced to Next.js, with additional experience in Vue and Svelte. I’ve also developed a mobile app using Expo Go and designed user interfaces for games in Unity and Roblox Studio. I often design my own UIs, but I’ve recently adopted third-party libraries for components like logos, which has helped me streamline my workflow and focus on delivering efficient, high-quality designs.

Backend

I started backend development 4 years ago with ExpressJS, initially working on a side project before continuing with school assignments. Since then, I’ve been consistently using ExpressJS for backend work. I’ve also developed numerous utility functions to ensure strong typing across both frontend and backend, which enhances developer experience and improves code maintainability. Recently, I’ve expanded my skill set by coding APIs within Next.js, aiming to reduce costs and further broaden my knowledge of different API frameworks.

Blockchain

My initial interest in blockchain began when I created crypto trading bots in 2020, although I didn't work with blockchain directly until later. When Axie Infinity started to gain traction, I decided to create my own version of the game, which kickstarted my passion for Web3 side projects. I also incorporated blockchain technology into my thesis.

Game Development

I'm proud to say that my programming journey began with game development. I started by creating mobile games using visual scripting tools in Game Salad and Buildbox, and then transitioned to real coding with Unity. This process significantly enhanced my understanding of both coding and design. I’ve published several games on the App Store and Google Play, although they are no longer maintained and have been removed by Apple and Google—though one game is still available for download. My experience with app publishing has also given me valuable insights into CI/CD for mobile development. Additionally, I’ve worked on films using Unreal Engine 5, further broadening my technical and creative skill set.

CI/CD

My first experience with CI/CD was when I deployed my own website on a VPC. For both school projects and side projects, I used GitHub Actions to automate updates to my website, and to this day, I still rely solely on GitHub Actions. My experience with CI/CD grew further through my project, Qitchat, where I used CI/CD pipelines to deploy backend servers within a monorepo to AWS ECR, and then deploy them to ECS.

Infrastructure Engineering

My experience in Infrastructure Engineering is admittedly limited, as I was unable to create a production environment for Qitchat, despite having planned it out. For building the infrastructure for Qitchat, I used Terraform and AWS. During this process, I gained hands-on experience with services like ECS, ECR, RDS, ElastiCache, VPC, Subnets, Gateways, Public and Private IPs, Load Balancers, and more. Additionally, I have some experience configuring Nginx to route APIs, as I used VPCs in a monolithic architecture for some side projects.

Cybersecurity & Pentesting

I started white-hat hacking at 17 in February 2020. Through penetration testing, I gained strong knowledge of vulnerabilities like XSS, RCE, DoS, SSRF, CSRF, and IDORs. I’ve worked on penetration tests for major companies like Google, Shopify, PayPal, and GitHub, finding serious issues such as DoS attacks, gift card exploitation, bypassing chat app security, and data manipulation in crypto/finance platforms. I earned over 3.5M PHP in rewards for high-value security reports. My experience in backend development, along with tools like Linux, Python, JavaScript, and Burp Suite, has supported my knowledge in cybersecurity. My pentesting experience has made me more careful when developing backend APIs to ensure they are built with solid security practices.

Artificial Intelligence

My experience with AI is still growing. In my personal projects, I developed a basic AI that learned to play Flappy Bird. Additionally, I’ve explored generative AI tools like Midjourney and Stable Diffusion, and experimented with AI services from cloud platforms such as AWS and GCP. This includes working with AWS tools like Rekognition and Comprehend, as well as GCP's Cloud Vision and Natural Language. In my free time, I continue to study and expand my knowledge of AI.

Hardware

My only experience in coding hardware would be with Arduino for a major project we had back in 11th Grade

Algorithms

Algorithms and logic are my favorite parts of programming; I truly enjoy working on them. Since I started programming almost six years ago, I’ve never stopped, even coding on weekends. While I may take short breaks here and there, I always come back. I find that when I'm working on logic-based problems, I feel a great sense of accomplishment whenever I solve them.
