Software Engineer | Founding Engineer | Systems & Infrastructure


About Me

I am a software engineer and founding engineer focused on building and scaling production systems across cloud infrastructure, backend services, and full-stack applications. I specialize in taking products from zero to production, designing reliable systems, and owning architecture end-to-end.

While my professional work centers on infrastructure and backend engineering, I actively build AI/ML systems in my free time, with a focus on LLMs, data pipelines, and applied machine learning.


Currently Working On

  • Building and scaling production systems at F4 Industries
  • Designing secure cloud infrastructure and CI/CD pipelines on GCP
  • Developing backend services in Rust and Python for real-world applications
  • Exploring AI/ML systems and LLM applications in personal projects

Experience

Founding Engineer @ F4 Industries (YC S25)

  • Built and scaled production systems, transitioning prototypes into Rust-based services
  • Architected full GCP backend infrastructure (auth, licensing, secure services)
  • Owned CI/CD pipelines and deployment for multiple live customer-facing products
  • Developed core systems including OCR/PDF pipelines, file processing, and backend services

Consultant @ Pariveda

  • Delivered features for enterprise React + Nx applications hosted on AWS
  • Built licensing and subscription systems with Stripe for multi-tenant platforms
  • Developed admin tooling and improved UI/UX across client-facing systems

Team Lead / Software Engineer @ University of Alabama Libraries

  • Led development of software, ML systems, and APIs across 20+ research projects
  • Built data pipelines, OCR systems, and large-scale analysis tools
  • Developed and deployed LLM-powered applications and evaluated local models
  • Created HPC workflows using multiprocessing and parallel computing

Projects (AI / ML – Personal Work)

  • Penny (AI Financial Advisor)
    AI system that analyzes transaction data and generates personalized financial insights

  • LLM API (Local + Cloud Hybrid)
    REST API for running LLMs (Llama, Mixtral) locally for privacy-focused workflows

  • PubMed Dashboard
    Data platform processing thousands of research papers with real-time visualization

  • Library AI Chatbot (RAG)
    Full-stack chatbot using embeddings and retrieval-augmented generation


Currently Learning

  • Distributed systems design and fault-tolerant architectures
  • Low-level performance optimization in Rust
  • Advanced LLM systems, evaluation, and retrieval techniques
  • Scalable data infrastructure and streaming systems

Looking to Collaborate On

  • Backend-heavy or infrastructure-focused projects
  • Distributed systems and scalable platforms
  • AI/ML projects (LLMs, data pipelines) on the side

Areas of Expertise

  • Distributed Systems and Cloud Infrastructure (GCP, AWS, CI/CD)
  • Backend Engineering (Rust, Python, APIs, Microservices)
  • System Design and Production Architecture
  • High-Performance Computing and Parallel Processing
  • AI/ML Systems (personal projects)

Tech Stack
