David Rodriguez — Software Engineer

The (story)
starts here.

I'm a freelance software engineer who builds production AI applications and full-stack systems, turning complex problems into tools real teams actually use, from agentic LLM pipelines to real-time ops platforms.

What sets me apart: nearly a decade in international trade and logistics before my CS degree means I understand the businessbehind the software. I don't just write code. I understand the domain problems deeply, so what I build actually fits your workflow, not just a clean demo.

I've built and maintained production systems for a $70M+ contractor operation as its sole developer. 80+ active projects, real stakes, no hand-holding. Now I bring that same ownership mindset to freelance clients who need things built right the first time.

(what)
I BUILD

Web Design & Development+

Mobile Apps+

Cross-platform mobile apps built with React Native that feel native on both iOS and Android. From MVP to production-ready — user auth, push notifications, offline support, and API-backed data. Ideal for businesses that need a mobile presence without maintaining two separate codebases.

Internal Tools & Automation+

Custom internal software for teams that have outgrown spreadsheets. I design and build the tools your operations actually need — project trackers, approval workflows, automated reporting, and multi-service integrations — replacing manual processes with reliable, low-maintenance software.

I build production apps your team will actually use every day[ - ]

For a construction operations team, I built and maintain two AI-integrated web applications relied on daily by 100+ employees: a bid management platform and a delivery tracking portal. I also automated insurance compliance reporting end-to-end, eliminating a manual workflow entirely. These aren't prototypes. They run in production.

I handle everything from kickoff to handoff. You won't babysit the process.[ + ]

Working with import/export clients under DaveBuilds.Tech, I owned the full engagement: scoping requirements, integrating LLM APIs, shipping the product, writing handoff documentation, and supporting clients until they could operate independently. You stay focused on your business.

“My approach: understand the domain deeply, then build systems that solve real operational problems — not demos that look good in a pitch.”

(how I)
WORK.

DISCOVERY

Understand the domain before writing any code.

I learn how your team actually operates — the workflows, the bottlenecks, the workarounds people have built around broken tools. Real problems hide inside daily operations, not requirements documents.

SCOPE

Define the smallest thing that solves the real problem.

No scope creep, no demoware, no over-engineering. I ruthlessly cut anything that doesn't move the needle on the actual outcome you're paying for.

BUILD

Production-grade from day one.

Real data, real users, real integrations — AI APIs, third-party services, your existing systems. Built to handle production load, not just look good in a pitch deck.

SHIP & HANDOFF

Documentation, training, and support until you own it.

I don't disappear at launch. Handoff includes written documentation, walkthroughs with your team, and ongoing support until your people can operate the system independently.
