Experience
3 rolesSoftware Engineer
JurisTechBuilding features across an enterprise loan origination system for banking clients, working on the web application itself as well as the API layer that integrates it with the mobile version. Day-to-day work spans backend PHP, query optimisation across Oracle, MariaDB, and DB2, and SOAP/REST integrations, plus client deployments, disaster recovery, and on-call production support, increasingly through agentic AI development workflows.
Software Developer
Kasatria TechnologiesEmbedded in the internal R&D team, building tools to streamline colleague workflows: a multi-source Google Sheets automation, automated test coverage to cut manual verification, and a web-based prototype navigator with clickable hotspots to simulate user journeys without product code.
Software Engineer Intern
KOLLECTResolved UI and data bugs across a Laravel debt-collections platform serving multiple clients, from client meetings through to fixes and testing, and optimised slow queries. Drove a Laravel 6→11 upgrade, refactoring raw SQL to Eloquent ORM so the client could integrate with newer systems.

Browser extension that filters explicit content in real time. Dataset built by scraping Google and Reddit using their APIs, then resized and split for training. A fine-tuned MobileNetV2 model classifies images into 10 sensitivity levels, and users set their own threshold to control what gets blurred.
JAVASCRIPT · PYTHON · MOBILENETV2 · WEB SCRAPING · CNN ML Research↗SkinCNN
Skin-disease classification model built with PyTorch. Data collected via web scraping, then multiple training iterations with architecture experiments tracked across 9 runs, each with its own confusion matrix and feature-map visualisations.

News management system with role-based access control for editors, staff, and readers. Article publishing, category management, user authentication, and email verification.
PHP · MYSQL · PHPMAILER Embedded↗Orchies
Automated orchid-watering system on ESP32. Reads temperature, humidity, soil moisture, and tank level, then uses a fuzzy inference system (27 rules, 3 inputs) to set exactly how long to run the pump. Monitored remotely via Blynk.
