I help startups and product teams build or modernize SaaS and mobile products and add AI features to existing software. With 12+ years of experience, I work with React, Node.js, TypeScript, React Native, GCP, and AWS from architecture through production. Typical engagements: โ€ข Full-stack SaaS development and modernization โ€ข React Native mobile development, performance, and production debugging โ€ข AI feature integration using local or hosted models, with structured outputs, evaluation, error handling, and streaming UX โ€ข APIs, authentication, payments, accounting, search, and other third-party integrations โ€ข Architecture reviews and difficult cross-layer production issues Relevant experience: โ€ข First technical hire at HedgeFlows, where I took customer and admin applications from empty repositories to production, then shifted primarily into backend work. I created and managed Node.js/TypeScript microservices on GCP and designed resilient Firestore-to-Elasticsearch synchronization that recovered real production failures. โ€ข First technical hire at Fluyo, where I established the TypeScript architecture across React Native, Node.js/GCP Cloud Functions, Firestore, authentication, and cloud storage. I independently delivered three major mobile iterations, then led three engineers through public iOS and Android launch. โ€ข Primary engineer for Craft's centralized Node.js/TypeScript identity service supporting three products and at least three engineering teams on a platform trusted by Fortune 500enterprises, the DoD, and 40+ federal agencies. I delivered Redis-backed token storage, PostgreSQL tenant isolation, extensive automated tests, and production releases through existing AWS infrastructure. โ€ข Founder and solo engineer at Blind Tech, responsible for the full technical stack and final technical decisions for a working internal alpha of a local-first AI-powered application spanning Rust, Tauri, React, local and hosted models, streaming speech, memory, and evaluation. I stay hands-on while contributing to architecture, implementation, code review, testing, deployment, and clear client communication. I can join a greenfield build, modernize an existing system, or investigate a difficult production problem. If you need a senior engineer who can take ownership across product and technical boundaries, send me the product context, current stack, and the outcome you need.

Did you know that 68% of MVPs fail within months of launch? Budgets blow up. Deadlines slip. Most teams lose focus on what actually matters. Sound familiar? I'm Herman, CEO of Coding House Studio. As your future technical partner and a mobile app development team, we help advertising agencies and small to mid-size businesses launch MVPs the right way โ€” fast, focused, and without cutting corners. We build products ready to grow, centered on the features that matter most, and designed to get your idea in front of real users as quickly as possible. We reduce time to market by 40% compared to traditional alternatives by focusing strictly on high-impact MVP features. We've been doing this for over five years and we understand what our clients need, often before they say it. More than 20 projects delivered across North America. In Q1 of 2026, three of our clients went live on both the App Store and Google Play. We know what it takes to go from idea to launch as a mobile app developer โ€” and we help you get there without wasting time or money. Our mobile app developer team of 15 handles everything from rough notes to a polished, ready-to-launch product. Most projects ship in 4 to 12 weeks, with ongoing support if you need it. We use AI to build faster and smarter โ€” and help our clients integrate AI directly into their own apps. You get a clear path from idea to a working mobile app that launches, gets users, and scales. Instead of just development, you get a mobile app developer team focused on real outcomes for iOS and Android. If your mobile app developer process slows down or becomes too complex, you get structure and clarity. If you already have a mobile app, you get help with new features, API integration, and performance improvements. If you are starting from scratch, you get a clear path to MVP launch with an experienced mobile app developer by your side. Our clients rely on us for transparency. We help you figure out what your MVP needs right now โ€” and what can wait.

You need software that works the first time, ships on schedule, and doesn't require you to babysit the developer. That's what you get here. Most of my work has the same shape. A business outgrew its spreadsheets, shared inboxes, and someone's memory, and now needs a real web application โ€” scheduling, dispatch, records, customer portals, admin dashboards, role-based access, reporting. Django or Flask on PostgreSQL, structured to maintain for years instead of to demo once. Increasingly that application needs AI inside it, and most of what gets sold as AI work is a chatbot bolted onto a website. What I build acts on your own data: retrieval pipelines over your documents, extraction that pulls structured fields out of scanned PDFs and flags what it isn't sure about, and agents that do work instead of answering questions. I've built a document knowledge base for an inspection company, clinical-indicator extraction from scanned referral documents for a home health agency, and a pipeline I built and run that parses thousands of government solicitation PDFs every month. Published AI researcher (arXiv:2602.16760) with original work on privacy-preserving LLM inference. Where I'm unusual: when the application has to talk to the physical world, I don't hand it off. I've built the sensor side too โ€” a pressure-cycling test system with live data and calibration, a paint booth monitoring suite, a wireless conveyor counter, a cellular RS-232 bridge, and a commercial instrumentation product I built and still sell. Most developers stop at the API. Most integrators stop at the dashboard. If your project crosses that line, you don't need two vendors and a meeting between them. And you get a developer who thinks like a business owner, because that's what I was for 16 years. I ran a multi-state industrial services company โ€” $2M+ annual revenue, 40 employees, 10 field units. I understand deadlines, stakeholders, P&L impact, and what "done" actually means. You won't need to chase me for updates or explain why something matters to your business. What I've shipped Web applications and backends: a carrier dispatch platform with real-time tracking, a field-services booking system with city-level lead attribution, a management suite for a backflow-testing company, an operations suite for a home health agency, and a $16,900 Python web application delivered at 5 stars over 260 hours. Currently building an on-premises records platform with multi-state search across about a million sensitive documents and zero cloud dependency. AI in production: a pgvector document knowledge base with multimodal PDF parsing and grounded question answering, OCR plus LLM extraction of clinical indicators from scanned hospice referral documents, construction-plan extraction pulling steel member specs off architectural drawings, and my own agent infrastructure โ€” vector memory, task routing, tool use โ€” that I run daily and build client systems on. Industrial and field systems: pressure-cycling test automation, automotive paint booth monitoring, real-time conveyor counting, WITS data streaming, and mobile field-inspection apps with photo capture, GPS, and offline sync. Data and automation: high-volume fault-tolerant extraction with Selenium, BeautifulSoup, and Playwright โ€” proxy rotation, session management, pipelines that still run months later. Why clients stay โ€ข No handholding. You describe the problem. I deliver the solution, flag risks early, and communicate proactively. โ€ข Business owner mindset. Your budget, timeline, and ROI matter to me, not just the code. โ€ข One developer, whole stack. Sensors, backend, database, frontend, AI โ€” no coordination overhead and nobody to blame. โ€ข Written weekly updates. You always know where the project stands without asking. โ€ข Top Rated Plus, about 75% repeat business. Clients come back, which is the only metric that can't be gamed. Industries: Manufacturing, Healthcare, Legal, Transportation/Logistics, Financial, Construction, Automotive, Property Services, Government/Defense Contracting. Tell me what you're building. You'll get an honest assessment of fit โ€” and if it's a match, you'll get it delivered. US-based and highly responsive.
