Edberto Tosoy
Software Engineer · Full Stack · Cloud
Software Engineer with production experience building and supporting enterprise banking applications. I work across frontend, backend, databases, and APIs, and have expanded into cloud-native development through hands-on work with AWS, Docker, Kubernetes, Terraform, CI/CD, and observability.

Experience
Built in production.
A collection of the roles, teams, and experiences that have shaped how I think, collaborate, and build software.
Software Engineer
Metrobank (via 98Labs Inc.)
- Built and maintained production React and TypeScript banking interfaces for teller and administrative workflows.
- Integrated REST APIs and implemented forms with Redux, Ant Design, React Hook Form, and SCSS.
- Investigated and resolved production defects, tracing issues across application logic and user workflows.
- Developed and maintained Cypress end-to-end tests covering critical banking workflows and regression scenarios.
- Worked with QA engineers, business analysts, and developers on requirements, defect resolution, code reviews, and delivery.
- Consolidated FX transaction charge logic and form-state handling, reducing the component from approximately 1,600 to just over 700 lines of code. This is a code-size reduction; no runtime performance improvement was measured.

Changelog
The journey so far.
The milestones, decisions, and turning points that have shaped my path as a software engineer.
Sep 2026 — Present
Gaining firsthand startup experience
Began collaborating with an early-stage international startup, gaining exposure to business development, strategic discussions, and the challenges of building a company.
Contributed to research and preparation for international startup initiatives while learning more about accelerator programs, market expansion, and early-stage business decisions.
Aug 2026
Exploring startups and entrepreneurship
Began actively pursuing opportunities at early-stage startups through Wellfound, drawn to the opportunity to work closely with founders, take greater ownership, and contribute across engineering and product development.
Explored entrepreneurship, startup business models, and the process of turning ideas into viable products. Developed a stronger interest in eventually founding a company of my own.
Started exploring startup literature, including The Lean Startup, and concepts such as validated learning and Build-Measure-Learn.
Jul 2025 — Present
Independent full-stack and backend engineering
Completely rebuilt my development environment on NixOS, switched to the Dvorak keyboard layout, moved to Neovim, and built a keyboard-driven workstation.
Built a strong DevOps foundation with Docker, CI/CD, Terraform, AWS, Prometheus, Grafana, and Kubernetes basics.
Expanded my independent projects with NestJS, Nx monorepos, RabbitMQ, event-driven architecture, and backend services.
Sep 2021 — Jun 2025
College and continued engineering learning
Completed a Bachelor of Science in Information Technology at FEU Roosevelt Marikina in June 2025.
Joined an IT organization, traveled, attended startup and tech events, and read books that reshaped my perspective.
Deepened my understanding of computer networking by learning DNS, HTTP/HTTPS, subnetting, firewalls, ACLs, load balancing, Nginx, reverse proxies, and VPNs.
Feb 2021 — Jul 2022
First commercial software engineering role
Worked as a Software Engineer at Metrobank (via 98Labs Inc.) while continuing college through remote work.
Worked across multiple teams, integrating front-end applications with REST APIs and maintaining end-to-end tests with Cypress.
Built reusable banking interfaces using React, TypeScript, Ant Design, React Hook Form, Redux, and SCSS.
Mar 2020 — Feb 2021
Turning Lockdown into an Opportunity
Used the lockdown to teach myself HTML, CSS, JavaScript, React, SCSS, Node.js, Firebase, Figma, and UI/UX design while building projects to reinforce what I learned.
Built my first practice project: edtosoy-match.firebaseapp.com
Created my first portfolio: edtportfolio.netlify.app
Expanded into full-stack development with Next.js, Apollo GraphQL, TypeGraphQL, TypeORM, Express, PostgreSQL, MongoDB, JWT, Cypress, and Jest, then launched my second portfolio: ed-tosoy-portfolio.vercel.app

The Spark That Started It All
Like many kids, I thought hackers were the coolest people alive—black hoodies, Linux terminals, and endless command lines. That curiosity led me to Linux, Bash, and Git.
Started with Python, NumPy, and Pandas during the data science boom, but eventually discovered I enjoyed building something more than analyzing data, so I transitioned to backend development with Django and Flask.
