Full-Stack Engineer · SaaS · Scalable Backends · Applied AI

I build production web applications and enterprise software — and I'm currently
going deep on AI systems (RAG, agentic workflows) on top of that foundation.

About

I'm a full-stack developer who enjoys taking a product from a vague requirement to a deployed system that real users depend on. Most of my work lives on the backend and architecture side — auth, authorization models, data design, service boundaries — paired with React/Next.js front-ends that make those systems usable.

Recently I've been focused on applied AI: integrating LLMs into existing products, building retrieval-augmented generation (RAG) features, and learning how to design agentic workflows responsibly inside production software rather than as demos.

  • 🏗️ I think in terms of systems and trade-offs, not just features.
  • 🔐 I care about correct authorization (RBAC/ABAC), audit trails, and data integrity.
  • 🤖 I'm actively leveling up in AI engineering — RAG, embeddings, and tool-using agents.
  • 🐧 I'm comfortable in Linux, Docker, and the full deployment lifecycle.

What I'm Working On & Learning

Growing from "developer who integrates AI" into "engineer who designs AI-native systems."

  • RAG pipelines — chunking, embeddings, retrieval quality, and grounding LLM output in real data.
  • Agentic workflows — tool-using agents that automate multi-step business processes.
  • Gemini API integrations — structured generation and content automation inside live products.
  • DevOps fluency — containerized deployments, CI/CD habits, and observability.

Featured Projects

🧪 Trialion — Clinical Data Management System (CDMS)

Enterprise platform for capturing and managing clinical study data — regulated, audit-heavy, and isolation-first.

A modular CDMS built for an environment where data integrity and traceability are non-negotiable. The interesting engineering here is less about CRUD and more about governance: who can do what, proving it later, and keeping every customer's clinical data fully isolated. Instead of a shared multi-tenant database, each customer is shipped their own dedicated instance — the strongest isolation guarantee, and the expectation for regulated clinical systems. Audit trails and electronic signatures are designed toward 21 CFR Part 11 expectations.

  • Dynamic Form Builder — configurable data capture (eCRFs) without redeploying.
  • RBAC / ABAC authorization — fine-grained, attribute-aware access control.
  • Audit trails & electronic signatures — every change attributable and verifiable (21 CFR Part 11).
  • Single-tenant, isolated deployments — a dedicated instance per customer for full data isolation.
  • Workflow automation over studies and user management with a modular service design.

🛰️ AerialBorne

Commercial drone-service marketplace connecting partners with customers.

A two-sided platform where I built out partner onboarding, the service catalog, and the first AI-assisted features — using the Gemini API to generate service descriptions and reduce manual content work.

  • Partner management & service marketplace with scalable backend services.
  • AI-generated service descriptions (Gemini API) feeding the catalog.

Engineering Focus

How I approach building software:

Area What it means in my work
System Design Clear service boundaries, sensible data models, and trade-offs I can defend.
Authorization Treating access control (RBAC/ABAC) as a first-class part of the design.
Deployment Isolation Shipping dedicated single-tenant instances so each customer's data is fully isolated.
Auditability Building systems where actions are traceable — audit trails, signatures, history.
Scalability Designing backends that grow without a rewrite.

AI & Automation

I treat AI as an engineering discipline, not a feature checkbox. My current focus:

  • RAG — retrieval quality, chunking strategy, and grounding answers in source data.
  • LLM integration — wiring the Gemini API into real product flows (e.g. AerialBorne).
  • Agentic workflows — letting tool-using agents handle multi-step processes reliably.
  • Honest scope — I'm learning fast and shipping; I describe what I've built, not hype.

Learning Journey

I keep a deliberate learning track alongside shipping work:

  • 📚 Now: RAG architecture, embeddings, and agent design patterns.
  • 🛠️ Next: Deeper DevOps — orchestration, monitoring, and infrastructure-as-code.
