Great products don't get built so much as sweated over — every layer.

Full-stack web and mobile, particular about everything from the database schema to the last pixel — plus a soldering iron for the weekends.

The person behind the code

LYSANDER UY10.3157° N · 123.8854° E

I'm a full-stack developer from Cebu with 2+ years of experience shipping production software. I'm at home across the whole path of a product, from the database schema and API design down to the interaction details users actually feel.

I've shipped features across a portfolio of production apps at Symph, built and merged mobile work for Focus Bear, and take on freelance builds of my own.

Away from the editor I compete in robotics and tinker with hardware and embedded systems, the same curiosity that keeps the software work honest.

Where I've been building

01Feb 2026 – Jun 2026·Mountain View, CA (Remote)

Full Stack Developer Intern

Symph

Shipped features and bug fixes across a portfolio of 5 products spanning healthtech, sports, and AI, covering full-stack implementation from API to UI
Implemented end-to-end testing with Jest across multiple products and contributed to deployment and release cycles on GCP
Led facility outreach for CourtHub, visiting 5+ facilities to pitch and demo the platform, directly driving customer acquisition
Produced short-form animated marketing videos using a multi-tool AI pipeline: Flow for image generation, ElevenLabs for voiceover, and Grok for image-to-video

02Feb 2026 – May 2026·Melbourne, VIC (Remote)

Mobile App Developer Intern

Focus Bear

Developed and merged 5+ features for the Focus Bear mobile app, improving user experience across iOS and Android
Identified and resolved bugs, wrote automated tests, and performed manual testing to ensure feature stability and reliability

032024 – Present·Cebu

Freelance Full-Stack Developer

Independent

Developing a DOH Lab Form Automation system for medical technologists with parallel processing of lab results across multiple departments driven by physician requests
Built PickASlot, a court booking system for a residential subdivision in Lapu-Lapu, Cebu with public availability browsing and admin-managed reservation confirmation, now in talks to expand to more courts under construction
Built BallRuns, a real-time pickup basketball app for a local ball club in Cebu with live player queues, host-managed teams, and instant score updates

042024 – Present·Cebu

Freelance Embedded / Hardware Developer

Independent

Designed the complete electronics and firmware for an automated medical glove-doffing system, commissioned by a group of students, driving an Arduino with a CNC shield to coordinate stepper motors, servos, and vacuum actuation for a hands-free sequence that grips, stretches, and peels the glove off the hand

Thesis

Computer VisionCode↗

C.Scope.AI

Automated imaging system that classifies microplastic samples under a microscope. A motorized XY platform scans petri dishes while a convolutional neural network identifies particles in real time, replacing slow, error-prone manual microscopy. Reached 91% accuracy with an on-device retraining pipeline.

05/Spotlight

Built overnight, because I needed it myself

Picklers is a community-run directory of every pickleball court in Cebu, not a booking platform, just the most accurate list of where to play and how to book, kept current by the players who actually show up.

Things I've built

Production web apps shipped to real users, and hardware I designed and fabricated end to end. Work that spans the browser and the physical world.

Web & Mobile04

Booking App01 / 04Live↗

PickASlot

Court booking system built for a residential subdivision in Lapu-Lapu, Cebu. Guests browse hourly slots and submit reservations, and bookings confirm after an admin verifies GCash or cash payment. Now in talks to expand the system to more courts under construction.

Live Game App02 / 04Live↗

BallRuns

Real-time app for running pickup basketball games, built for a local ball club in Cebu. Hosts open a run, share a six-character code, and players join a live queue while the host assigns teams, runs the clock, and logs scores. Everyone sees updates instantly, no refresh.

Automated Glove Doffing Device

Medical Device

Vacuum-assisted device that removes medical gloves with no hand contact, targeting the self-contamination that makes manual doffing a critical safety failure point. Built the prototype and ran 180 trials across glove sizes and wear conditions, meeting its 30% contamination-reduction target.

Advanced Line Follower

Autonomous Robot

My most recent and most refined line-following robot. I designed and fabricated everything myself: a custom 16-channel reflectance sensor board, the controller board, and a 3D-printed chassis. The dense sensor array reads the track at fine resolution for tight, confident cornering at speed.
