👨‍💻 Well hello there! Thanks for checking out my profile. A little about me: I have nearly 20 years experience as a software developer working for large fortune 500 companies. Now I spend most of my time doing freelance work building Google Apps Scripts projects for clients. I have an eye for design and love building sleek and attractive apps.

Reasons to team up with me: 🎨 Aesthetic designs 🔧 Reliable and long lasting engineering solutions 📱 Automation and workflow improvements ⚙️ User friendly configurations 🔮 Fortune telling for your business! (Okay, okay...I jest, I jest) I specialize in Google Workspace products: ✔️ Google Sheets ✔️ Gmail ✔️ Google Forms ✔️ Google Calendar ✔️ Google Docs ✔️ Google Slides ✔️ Web apps ✔️ etc. I can integrate all of these and other GSuite/GWorkplace products for you as well as creating interfaces to other products outside of Google via APIs. Some commonly requested API connections to various platforms: ✔️ Quickbooks ✔️ Wise ✔️ Stripe ✔️ Zapier ✔️ Webhooks ✔️ OAuth 2 and other authentication schemes I have been able to bring my career as a Full Stack Developer to bear on the Google Workspace/Apps Script environment and deliver solutions to clients that are efficient, tested, and functional. There are many developers that can code a solution that works, but it's also important to find someone that does proper design work and chooses the best out of many possible solutions so the deliverable runs efficiently and has longevity. I can't tell you how many times I've had clients come to me to fix a poorly designed app that needs an overhaul.

He is literally the BEST freelancer I have ever used on UpWork over well more than 10 years across multiple companies. We wanted to automate the creation of a daily KPI report we use to monitor our business. We have a team member that was spending 5 hours per day completing it. He was using data pulled from 4 or 5 different software applications. Our team member now spends about 1 hour per day and the other 4 hours per day is automated so he is freed up to work on other things now. We love it and our team member REALLY loves it! Stephen set the appropriate expectations about the project up front. He overcame multiple challenges. He created detailed video instructions for our team on how to use the final KPI and complete the information. He delivered so MUCH more than he promised. This is just the first project of many we will do with him. I didn't know he was the right choice when I hired him because he seemed similar to several others. WOW, he was worlds better than I could have imagined!" "All I can say is WOW! Stephens skills are absolutely incredible the attention to details and execution of this task was 2nd to none. One of the best freelancers we have ever used and will definitely be working with him again! Thanks again Stephen!" "Stephen was simply outstanding to work with and I will 100% be hiring Stephen again for future projects. In this particular project, Stephen was helping my team rebuild a pacing doc used every day by 150 sales professional who generate $200m annually. On top of his expertise, patience and determination to deliver, his biggest strength is his reliability. Stephen will get the job done. This project spanned six weeks and right over the holiday season and Stephen never failed to deliver and in all cases over delivered." "Working with Stephen was a absolute pleasure. He met and surpassed my expectations and added so much valuable input on how to structure things in the best and clearest way. I appreciated the continuous communication throughout and Stephen worked hard to get this involved project completed earlier then expected. Very skilled and a terrific person to work with!! I look forward to working with Stephen in the near future on the next phase of our project. Thank you!!"

👋 Great to meet you. What are the chances that something in your Google Workspace mostly works — but it’s slow, fragile, confusing, or harder to trust than it should be? I specialize in building operating systems for businesses from scratch. I’ve been doing this work full-time for over 5 years, across 119 completed Upwork contracts and 500+ projects outside of Upwork through my agency, Allen App Tools. What I’ve learned is this: Most people don’t just need automation — they need clarity, confidence, and ownership over systems their business now depends on. Many conversations start with some version of: “We rely on this sheet every day, but honestly we’re scared to touch anything.” — Sarah (Feb 2023) Or: “The last developer built it, but no one here understands how it works.” — Mike (Aug 2022) Or even: “It technically works… until it doesn’t.” — Jenna (Jan 2024) These aren’t edge cases. They’re patterns I’ve seen hundreds of times. That’s why my approach isn’t just about making something work — it’s about making sure it’s: ✅ understandable ✅ maintainable ✅ documented and safe to evolve as your business grows I help teams: ✅ Replace manual processes with reliable automation ✅ Clean up fragile or overgrown Google Sheets ✅ Build Apps Script systems that don’t break when requirements change ✅ Integrate Forms, Sheets, Gmail, Drive, APIs, and external tools ✅ Take ownership back from “black box” spreadsheets Very often, clients come to me after trying to DIY or after another developer stepped away: “We had something half-built and no idea how to move forward.” — Chris (May 2021) My job is to remove that uncertainty and replace it with something you can confidently run your business on. Communication & trust (this matters more than people admit) Good automation fails if it isn’t clearly explained. I put a heavy emphasis on: ✅ plain-language explanations ✅ walking through logic together ✅ making sure you understand what you’re paying for As one client put it: “You’re the first person who actually explained what’s going on in a way I can understand.” — Lauren (Nov 2022) I’d rather over-communicate early than leave you guessing later. This is not a side hustle for me — it’s my business. I’m here for long-term partnerships, not quick wins that leave you stuck later. “We’ve been burned by freelancers disappearing. That’s why this mattered to us.” — Tom (Jul 2020) When we work together, I care about where this system is headed, not just where it lands today. About me & my team When I’m not directly writing code, I’m building Allen App Tools, a Google Workspace automation company focused on giving people back time and sanity at work. You’ll always communicate with me directly — and when needed, I can bring in trusted developers from my team to help move faster without sacrificing quality. If you’re dealing with: 🤔 a Google Sheet that’s become mission-critical 🤔 an automation you don’t fully trust 🤔 or a process that’s eating hours every week I’d be happy to take a look and talk through options.

With over 20 years of proven technical and creative experience, I bring a broad, practical background to every project. My work spans the full software development life cycle, systems design, workflow automation, business process improvement, data analysis, field operations, dashboards, reporting tools, AI-assisted applications, music production, video production, audio engineering, mixing and mastering, and audio editing. I specialize in solving complex, messy technical problems with practical systems that improve accuracy, visibility, and efficiency. I build internal business tools and automation systems using Python, JavaScript, HTML/CSS, Flask, FastAPI, AppSheet, Google Sheets, Google Apps Script, Airtable, Trello, REST APIs, JSON, CSV, SQL, SQLite, MySQL, data extraction, ETL workflows, web scraping, OCR, QA testing, data validation, dashboards, reporting systems, internal tools, workflow automation, API integrations, AI integrations, local LLMs, NLP tools, prompt workflows, document processing, and lightweight web applications. Recent work includes field service management apps, technician dispatch tools, gas replacement workflows, inspection apps, quality-control review systems, geospatial map dashboards, 911 incident data viewers, Trello automation tools, project management dashboards, local LLM/NLP utilities, data cleanup workflows, reporting tools, and operations dashboards. I enjoy projects where a client has scattered data, repeated manual work, unclear handoffs, disconnected tools, or spreadsheet-heavy processes and needs someone who can design a cleaner workflow, build the system, test it, document it, and explain it clearly. I am extremely customer-focused and enjoy creating clear, useful, customized solutions for each client. My ability to understand customer needs, translate complex requirements, and exceed expectations is one of the key strengths I bring to every project. I am especially useful when a project is not fully defined yet and the client needs help turning a real-world problem into a practical build plan. At Xcel Energy, I designed, wrote, and tested full-stack systems for mapping, project management, materials tracking, invoicing, field operations, quality review, and internal reporting. I reduced human entry error across several internal systems, integrated APIs, conducted large dataset analysis and standardization, and developed business logic to improve visibility, accuracy, and efficiency across multiple business areas. This work gave me direct experience with safety-sensitive operations, field crews, inspection workflows, vendor coordination, data integrity, process design, and decision-quality systems where accuracy mattered. Over 10 years at Apple, I developed strong leadership, communication, and technical training skills through roles involving executive escalations, customer-facing technical problem solving, documentation, discovery, training, and cross-functional coordination. Apple strengthened my ability as a public speaker, trainer, and technical translator, helping me explain complex technical concepts clearly to people at any level of technical experience. My experience also includes deep core drilling with HP Geotechnical, extensive work in gas and electric transmission and distribution, high-pressure gas systems, and cross-city distribution fiber optics. I also have hands-on experience in robotics and computer vision design with Cyber Motion, where I worked on autonomous navigation and path planning concepts. I have invented and designed solar systems to mine Bitcoin and generate DC heat for large battery systems. My engineering education in Java and C++ gives me a strong foundation for my technical work and a deep understanding of software structure, system behavior, debugging, architecture, and the full development life cycle. In addition to my technical skills, I am an effective communicator, public speaker, mentor, and technical translator. I am comfortable bridging the gap between technical and non-technical stakeholders, helping teams understand what is possible, what is risky, what should happen next, and how to move from idea to implementation. I can work directly with business owners, managers, field teams, engineers, vendors, and clients to clarify requirements and turn them into practical next steps. My work has consistently led to increased efficiency, reduced errors, better process visibility, cleaner data, improved workflows, and practical innovation across multiple environments. I am passionate about using technology to solve real-world problems and aligning technical execution with business goals. I also have a strong record of mentoring, training, and helping teams perform better. My approach to problem-solving is both analytical and creative, allowing me to handle complex systems while still designing tools that are understandable and useful for real people.
