I have worked with Python, SQL, PostgreSQL, JSON, and structured data normalization and validation, building reliable workflows for internal and product-facing systems. In my recent work, I integrated AI-assisted tooling such as Claude Code and GitHub Copilot to speed up delivery while maintaining code quality through testing and disciplined Git-based workflows. I have experience building cross-platform applications with Next.js and React Native, as well as implementing backend integrations with Auth0, Firebase, Redis, and CI/CD pipelines. Previously, I supported production PostgreSQL databases and wrote ETL scripts in Python, improving query performance and data processing throughput for business-critical operations. I am looking for a junior software engineering role where I can continue growing in data pipelines, internal API integrations, and production system fundamentals within a remote, collaborative team. ## Skills ### [Python](https://jobicy.com/talent/python.md)[SQL](https://jobicy.com/talent/sql.md)[React](https://jobicy.com/talent/react.md)[Docker](https://jobicy.com/talent/docker.md)[Linux](https://jobicy.com/talent/linux.md)[CI CD](https://jobicy.com/talent/ci-cd.md)[Machine Learning](https://jobicy.com/talent/machine-learning.md)[Git](https://jobicy.com/talent/git.md)[PostgreSQL](https://jobicy.com/talent/postgresql.md)[Cybersecurity](https://jobicy.com/talent/cybersecurity.md)[ETL](https://jobicy.com/talent/etl.md)[Redis](https://jobicy.com/talent/redis.md)[Code Review](https://jobicy.com/talent/code-review.md)[Debugging](https://jobicy.com/talent/debugging.md)[JSON](https://jobicy.com/talent/json.md)[React Native](https://jobicy.com/talent/react-native.md)[Next.js](https://jobicy.com/talent/next-js.md)[scikit learn](https://jobicy.com/talent/scikit-learn.md)[Data Validation](https://jobicy.com/talent/data-validation.md)[Firebase](https://jobicy.com/talent/firebase.md)[Pytest](https://jobicy.com/talent/pytest.md)[Auth0](https://jobicy.com/talent/auth0.md)[Expo](https://jobicy.com/talent/expo.md)[Data Normalization](https://jobicy.com/talent/data-normalization.md) ## Tech Stack & Tools ### Application Hosting [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/firebase/firebase-original.svg) Firebase](https://jobicy.com/talent?tool=firebase.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/redis/redis-original.svg) Redis](https://jobicy.com/talent?tool=redis.md) ### Data Stores [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/postgresql/postgresql-original.svg) PostgreSQL](https://jobicy.com/talent?tool=postgresql.md) ### Development [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/docker/docker-original.svg) Docker](https://jobicy.com/talent?tool=docker.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/git/git-original.svg) Git](https://jobicy.com/talent?tool=git.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/linux/linux-original.svg) Linux](https://jobicy.com/talent?tool=linux.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/netlify/netlify-original.svg) Netlify](https://jobicy.com/talent?tool=netlify.md) ### Languages & Frameworks [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/expo/expo-original.svg) Expo](https://jobicy.com/talent?tool=expo.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/pytest/pytest-original.svg) PyTest](https://jobicy.com/talent?tool=pytest.md) ## Experience Software Engineer (Co-founder) @ Reactions Jan 2025 - Present Integrated Claude API for processing structured allergen data, automating ingredient scanning and risk analysis.
