I help startups and growing companies build, launch, and stabilize production software. Whether it's a React Native app that needs to ship, a backend that needs to scale, or an existing system that's become difficult to maintain, I take ownership and deliver reliable software from MVP through production. I've built mobile apps, SaaS platforms, internal business tools, cloud infrastructure, and backend APIs across healthcare, logistics, e-commerce, staffing, and AI. I'm comfortable starting projects from scratch, but I also enjoy stepping into existing codebases, identifying the real bottlenecks, and improving performance, reliability, and maintainability. Clients continue working with me because I don't stop at the reported problem. I investigate production systems, identify related issues before they become expensive, communicate tradeoffs clearly, and focus on building software that's dependable, not just functional. What I can help with * React Native & Expo mobile applications * Full-stack web applications * Backend API design & development * AI integrations & automation * Cloud architecture (AWS, GCP & Azure) * Production debugging & system reliability * Authentication, payments & third-party integrations * MVP development through production launch * Existing codebase improvements & modernization Technologies Frontend & Mobile React, React Native, Expo, Next.js, TypeScript Backend Node.js, Python, Java, Spring Boot, Flask, FastAPI Cloud & Infrastructure AWS, Google Cloud, Azure, Docker, GitHub Actions, Linux, SSL/TLS Databases PostgreSQL, MySQL, SQL Server, MongoDB, DynamoDB, Elasticsearch Professional Experience Hello Hotshot — CTO / Lead Engineer Owned engineering for a logistics SaaS platform from MVP through production. Designed backend APIs, authentication, cloud infrastructure, deployment pipelines, and production operations. NICE Systems — Cloud Applications Engineer Support and operate production cloud applications and distributed backend systems. Diagnose production issues, work across APIs and cloud infrastructure, and improve system reliability. Express Employment — Software Engineer Developed a resume processing and search platform used in staffing operations, including automated resume matching, OCR workflows, search capabilities, and Windows desktop deployment. WhatTuBuy — Founder & Lead Engineer Built a consumer web and mobile platform, including authentication, backend APIs, infrastructure, analytics, and marketplace functionality. Dr. Amy Miller Ltd. — Technical Engineer Maintain secure websites and business systems, including payments, hosting, encryption, and operational improvements. Selected Projects * Cloud photo storage platform * Consumer mobile shopping application * Android scheduling application * Autonomous robotics project How I work * I communicate clearly and consistently. * I take ownership rather than waiting for direction. * I focus on production-ready solutions, not prototypes that fall apart later. * I write maintainable code that other engineers can build on. * I integrate well with existing teams and can also lead development independently. If you're looking for an engineer who can take responsibility for your product, solve difficult technical problems, and help move your software from idea to production, I'd be happy to discuss your project.

Software engineer with 8+ years building and maintaining production C/C++ and Qt/QML systems on embedded Linux, most recently on agricultural guidance and control systems. While embedded and Qt work is my deepest specialty, my background in computer engineering fundamentals and years of working across complex, long-lived codebases means I'm comfortable taking on work outside that core when the problem calls for it. Core specialties: Embedded Linux application development in C/C++ Qt/QML development for HMI and cross-platform desktop applications (formal Qt/QML training completed) Python for tooling, automation, scripting, and data processing Cross-component debugging and production defect resolution on long-lived codebases Tracing system behavior end-to-end across legacy and active components Code review, design input, and release readiness work Also open to: General C/C++ and Python work outside the embedded space Legacy codebase maintenance, modernization, and Qt version migration Technical consulting, code review, and architecture discussions Adjacent problems where strong debugging instincts and systems-level thinking matter more than prior exposure to a specific stack AI-assisted engineering: I work daily with current AI coding tools (Claude Code, Codex CLI, Gemini CLI) and keep up with how they're evolving. My approach is to use them to increase throughput without compromising quality - maintaining repository-level instruction files, reusable prompts, and structured context so the tools produce consistent output; reviewing what they generate rather than accepting it blindly; and recognizing their failure modes (hallucinated APIs, missing context, overreach) before those failures ship. The result is faster work on large or unfamiliar codebases without the quality regression that comes from treating AI output as finished code. How I work: Full Agile/Scrum participation (sprint planning, reviews, retrospectives, occasional facilitation) Experienced in distributed teams with coordination across time zones Clear communication with both technical and non-technical stakeholders Good fit for: Embedded C++ projects on Linux Qt/QML HMI development for industrial, agricultural, or instrumentation equipment Cross-platform C++/Qt desktop applications (Qt 5 or Qt 6) Python scripting, tooling, and automation work Legacy C/C++ codebase maintenance or modernization Production debugging on systems where correctness and stability matter
