GeezerVison is showing profullstack.com — Profullstack, Inc. | Agentic Engineering AGENTIC ENGINEERING, SUPERVISED BY 30 YEARS OF EXPERIENCE Senior engineers running fleets of AI agents, with the rigor I learned inside Yahoo!, IBM, and PayPal.Most shops sell headcount and timelines. We sell agentic engineering: one senior engineer directs a fleet of coding agents on your codebase, and every change ships through review, tests, and CI. For teams that cannot afford to get it wrong. Yahoo! → IBM → PayPal → Now running agent fleets for select teams  PROFULLSTACK / DEVICE LAB // SELECT YOUR SIGNAL BLUE vs. REDTwo devices. Your rules.BLUE is PIT ONE Mini: one button, direct agent calling, no screen. RED is PIT ONE Pro — The Works: cellular, TronBrowser, calendar, and W3BS NET control. Choose your mode. Both are preproduction designs. BLUE $129/mo · RED $250/mo · 12-month plans · Second Pro $200/mo (20% off)   Who we work withFunded startups that need to shipYou have raised capital and need a product built at agent speed without cutting corners on architecture or quality. Teams adopting AI agentsYour engineers are trying Claude Code or Codex and getting uneven results. We set up the skills, guardrails, and review loop so agents ship production code. Businesses replacing a bad buildYour current app was built cheaply, breaks often, or cannot scale. You need a fractional CTO or a lead engineer who can rebuild it right the first time. This is not for people shopping for the cheapest website, or for a prompt and a prayer. It is for teams that need reliable, production-grade engineering with agents doing the heavy lifting.  Enterprise experience, agent speed“I spent 30 years building products at companies where downtime costs millions and shipping late is not an option. Now I point a fleet of AI agents at your codebase and hold their work to that same standard.” At Yahoo!, I learned how to build at scale. At IBM, I learned how to architect for reliability. At PayPal, I learned what it takes to ship products that handle real money and real users. Agents write most of the code now. That experience is what decides which of it gets merged.

Senior engineers own the outcome. 01 Agentic EngineeringA senior engineer runs a fleet of coding agents on your codebase. Every change is reviewed, tested, and shipped through CI. 02 Agent EnablementSkills, MCP servers, guardrails, and review loops so your own team gets production code out of Claude Code and Codex. 03 AI and LLM SystemsAgents, retrieval, tool use, and evals built into your product, with the failure modes engineered out. 04 Full-Stack Product EngineeringAgent-built web apps, APIs, and data layers on a proven stack, reviewed and tested from architecture to production. 05 Mobile and Desktop AppsCross-platform mobile, PWAs, and desktop apps that share one codebase with the web product. 06 UX and Product DesignUser-centered design that makes the product obvious to use and easy to build. 07 Smart Contracts and BlockchainAudited contracts, wallets, escrow, and payments across the chains that matter. 08 MVPsA free clickable mock in 48 hours, then an agent-built MVP you can put in front of users. 09 Fractional CTOArchitecture, hiring, and technical leadership from someone who has shipped at scale. 10 Security AuditsA fixed-price, full-scope audit with the fixes delivered as pull requests, not just a report. 11 Managed HostingDeployment, monitoring, and operations for the products we build and the ones we inherit. 12 SEO and DistributionTechnical SEO, link building, and paid distribution through our owned publishing network. ResultsWe measure success by what ships, how well it runs, and the business impact it creates. Security / Communications QryptChat — Quantum-resistant encrypted messagingProblem: Existing encrypted messaging apps rely on cryptography that will be broken by quantum computers. There was no production-ready messaging platform using NIST-approved post-quantum algorithms with real-time voice, video, and text. What we built: Built a full Progressive Web App using SvelteKit with ML-KEM-1024 (CRYSTALS-Kyber) key exchange and CRYSTALS-Dilithium signatures. Implemented real-time messaging with typing indicators and read receipts, encrypted 1:1 and group voice/video calls, phone-based authentication, multilingual support, and a Tor-accessible service for maximum privacy. Outcome: Live and operational at qrypt.chat. Supports multiple languages, works across all devices as a PWA, and delivers quantum-safe encryption that meets NIST standards. Fintech / Blockchain CoinPayPortal — Non-custodial crypto payment gatewayProblem: Businesses and AI agents needed a way to accept cryptocurrency payments across multiple blockchains without giving up custody of their funds. Existing solutions required KYC, locked funds in custodial wallets, or only supported a few chains. What we built: Engineered a non-custodial payment gateway supporting 15+ blockchains including Bitcoin, Ethereum, Solana, and Polygon. Built escrow services with trustless fund holding, a multi-chain web wallet with CLI and REST API interfaces, real-time transaction processing under 1 minute, and an AI agent integration layer so tools like Claude and ChatGPT can autonomously create wallets and process payments. Outcome: Processing 47,000+ transactions across 1,200+ merchants in 45+ countries with $8.2M+ in volume. 99.9% uptime. Live at coinpayportal.com. SaaS / Marketplace SaaSRow — SaaS discovery directoryProblem: Software founders had no easy way to get their products discovered without paying for expensive ad placements or directory listings. Existing directories charged high fees and had slow approval processes. What we built: Built a full-stack SaaS directory platform with free listing submissions, dofollow backlinks for SEO value, a fast approval pipeline, search and filtering, and category-based discovery. Designed for scale with server-side rendering and optimized for search engine indexing. Outcome: Live and growing at saasrow.com. Provides a free distribution channel for SaaS founders with real SEO value from dofollow links. Selected workA sample of products we have shipped across web, mobile, blockchain, and AI.
