Where I've worked

  1. – Present

    Full-Stack Engineer @ Gabriel AI

    • Led the migration of the customer-facing marketing site from a client-rendered React app to a Next.js static export (19 routes plus a CMS-driven blog). Lighthouse SEO went from unmeasurable to 100 on every page, image payload dropped by 86%, and all content became crawlable by search engines and AI bots for the first time.
    • Deployed on AWS Amplify with build config and env management, plus a one-command audit script (crawlability, structured data, sitemap, Lighthouse) that has to pass before each release.
    • Build and ship features across the platform: the dashboard and web app front end, back-end APIs and database logic, and AI voice calling workflows, with integrations for HubSpot, lead sources, Contentful, GA4 and Cloudflare Turnstile.
    • Own code quality end to end: tested code, debugging across the stack, and code reviews and planning with product, design and marketing.
    • Next.js
    • React
    • AWS Amplify
    • HubSpot
    • Contentful

  2. –

    Software Engineer @ TNM Software Solutions

    • Cut device power consumption by 30% fleet-wide by building battery-efficient location services in Kotlin, using the Google Geofencing API and motion sensors to reduce GPS polling.
    • Improved app performance by 50% and removed UI-thread bottlenecks by refactoring the legacy codebase to MVVM with Kotlin Coroutines for non-blocking I/O.
    • Shipped production Android and web apps from scratch, working in daily stand-ups and weekly sprints with the backend and QA teams.

    Android Developer Trainee @ Tops Technology Inc.

    • Built and released user-facing features with Android UI components and Material Design in Kotlin, and published them to the Google Play Store.
    • Designed normalized Room/SQLite schemas that sped up queries and made offline-first data sync reliable.
    • Structured MVVM repositories with clear UI, domain and data layers, integrating REST APIs through Retrofit, Coroutines and LiveData.

    Parkinson's Disease Detection Using Handwriting: A Hybrid Multi-CNN and Genetic Algorithm Framework

    99.2%external validation accuracy

    abstract

    An end-to-end hybrid framework for automated, non-invasive Parkinson's Disease detection from digitized hand-drawn graphomotor biomarkers. It combines deep feature extraction from multiple CNNs (ResNet50, VGG19, InceptionV3), Genetic Algorithm feature selection, XGBoost classification, and SHAP interpretability.

    Solving Information Overload: Using BERT to Recommend News Articles Related to User Interest

    SBERTsemantic ranking over a rich user profile

    abstract

    A content-based recommendation system that uses Sentence-BERT embeddings and a rich user profile built from explicit preferences, liked articles and reading history. Cosine similarity over all-MiniLM-L6-v2 vectors drives personalized news ranking, avoiding the limits of keyword matching.

    A Comparative Survey of PyTorch vs. TensorFlow for Deep Learning: Usability, Performance, and Deployment

    abstract

    Compares the two dominant deep learning frameworks across developer experience, training and inference efficiency, deployment, and ecosystem. Both deliver strong results, but PyTorch leans toward simplicity and research while TensorFlow leans toward a complete production ecosystem, so the right choice depends on which trade-offs matter most.

Let's build something together.

I'm open to full-stack, mobile and AI engineering roles, and I'm always happy to talk shop.
