Built Software Used by 300,000+ People Every Month | Custom Software
I’ve spent 6+ years building and shipping production software, including helping build the online ordering system for Dickey’s BBQ, used by 300,000+ people every month. My experience spans customer-facing products, internal operations platforms, business integrations, mobile applications, and AI systems. I’ve taken projects through product definition, technical design, development, launch, and years of continued improvement. 𝗜 𝗯𝗿𝗶𝗻𝗴 𝗯𝗼𝘁𝗵 𝗽𝗿𝗼𝗱𝘂𝗰𝘁 𝗷𝘂𝗱𝗴𝗺𝗲𝗻𝘁 𝗮𝗻𝗱 𝗵𝗮𝗻𝗱𝘀-𝗼𝗻 𝗲𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴. I help you decide what deserves to be built, what can be reused, how your systems should connect, and what the first release needs to accomplish. Then I stay hands-on with the implementation. That experience matters when your business has outgrown its tools and the next step isn’t obvious. I can assess the existing software, work through the constraints, challenge unnecessary complexity, and explain the options in plain language. Here are a few examples of the work behind that experience. • 𝗧𝗖 𝗘𝗹𝗲𝗰𝘁𝗿𝗶𝗰. Engineers needed answers they could verify across large technical documents. I built AI document search with source citations and page references. Engineer interviews and client estimates indicate an approximately 83% reduction in search time. The system is in production and still used. • 𝗘𝗿𝗴𝗼 𝗚𝗹𝗼𝗯𝗮𝗹. I helped build a connected customer support and follow-up system across website chat, in-app chat, and email. Website chat achieved a typical first response time of 36 seconds. Over five months, the support platform managed 11,782 conversations across seven inboxes. • 𝗧𝗡𝗠 𝗖𝗼𝗮𝗰𝗵𝗶𝗻𝗴. I built Leelou AI around the company’s coaching standards, with text and voice conversations, multilingual support, and HR reporting. Repeated testing with coaches helped translate their expertise into the way the product works. • 𝗜𝗻𝘁𝗲𝗿𝗻𝗮𝗹 𝗼𝗽𝗲𝗿𝗮𝘁𝗶𝗼𝗻𝘀 𝗽𝗹𝗮𝘁𝗳𝗼𝗿𝗺. A successful first build grew into a two-year partnership. I built a platform supporting 44 internal users and continued developing it around the client’s operations. Clients have described the experience this way: "You didn't just build features. You listened. The challenge was not only developing technology, but translating the human complexity of coaching into something usable." Zoran, TNM Coaching “Complex tasks can now be achieved much easier and faster on a regular basis.” Executive, Operations Platform Client I bring the same product and technical involvement to your business. Whether you need to connect disconnected tools, automate repetitive work, build an internal system, modernize legacy software, or maintain an existing application, I can help you make the decisions and deliver the work. You don’t need a finished specification. Bring me the business problem, the existing application, or the workflow your team keeps working around. I’ll ask questions, explain trade-offs, and recommend simpler approaches when they make sense. We agree on useful milestones and review working software as it develops. Clearly scoped work can start with a build milestone. If significant questions remain, we can begin with a focused paid planning engagement. I can continue with maintenance, support, and improvements after release. My technical work includes full-stack web and mobile development, API integration, workflow automation, dashboards, customer portals, AI agents, chatbots, and retrieval-augmented generation (RAG). Core technologies include React, Next.js, TypeScript, Node.js, Python, PostgreSQL, Supabase, AWS, Azure, GCP, and OpenAI and Anthropic APIs. Tell me what your business needs to do better and what is getting in the way. We can discuss the priority and the next useful step.
