Full-Stack Software Engineer
Building production web applications and intelligent systems.
Building production web applications and intelligent systems with a focus on product quality, developer velocity, and practical AI features.
Open to opportunities
Current Focus
Production-grade SaaS features, engineering workflow automation, and practical AI integrations.
Approach
Clean UX, scalable architecture, and measurable business outcomes over visual noise or trend-chasing.
About
I started by building polished frontend experiences, then moved deeper into full-stack product engineering and AI-powered workflows. Today I enjoy shipping reliable user-facing applications, integrating external systems, and exploring how retrieval, search, and agents can solve real operational problems.
Experience
SJ Innovation LLC
Junior Software Engineer — L3
Nov 2024 — Aug 2026
Progressed from L1 to L3 through consistent ownership and delivery.
Built production features across frontend, backend, payments, and operational tooling.
Worked on AI-assisted workflows and internal systems that reduced manual work.

Grew from frontend delivery into broader full-stack ownership across performance, backend integrations, operational tooling, and practical AI workflows.
Developed and maintained production web applications using React, Node.js, Express, and modern database systems, with a focus on reliable delivery and measurable performance improvements.
Architected Next.js SSR workflows and frontend performance enhancements that improved load times and raised overall application quality.
Built reusable responsive UI components with React and Tailwind CSS to create consistent user experiences across devices.
Designed and integrated REST APIs with Supabase and PostgreSQL for data workflows, authentication, and internal product operations.
Implemented RAG-oriented workflows, vector search, semantic retrieval, and hybrid search approaches for practical knowledge retrieval use cases.
Worked within Git-based PR workflows, code reviews, and AI-assisted development processes to ship features faster in Agile teams.

AI & Engineering
Retrieval That Supports Product Work
I’m exploring RAG, semantic retrieval, HyDE, and hybrid search with a focus on when they improve product quality, not just demo quality.
Agentic Engineering Workflows
I’m interested in MCP-powered tooling, agent skills, and operational automations that help teams review, search, and ship faster.
Production Constraints First
My approach is grounded in reliability, observability, and maintainability so AI features fit into real systems instead of living as isolated experiments.
