Technical Project Manager / Delivery Lead for SaaS, AI, and mobile products. I rescue delayed launches and own delivery through production. When a product is stuck, the problem is often unclear ownership across roadmap, engineering, QA, and launch. I bring those pieces together and drive the work to a reliable release. Since 2007 at GCGI, I’ve led 475+ software deliveries across distributed teams in the US, Europe, and Latin America. NextBlock launched in 28 days and reached $250K in its first 60 days. Interviewiz scaled to 10,000+ monthly sessions. I can own: - Roadmap prioritization and delivery planning - Distributed PM, engineering, design, and QA coordination - Sprint planning, backlog refinement, and risk management - Executive and stakeholder communication - Production readiness, release coordination, and post-launch delivery Technical fluency: React/Next.js, Supabase, Stripe, Python/FastAPI, AWS, OpenAI, and Claude. I speak engineer, so business goals become shippable plans. Available for fixed-scope rescue engagements and long-term contracts. Start with a paid Rescue Assessment: I’ll identify the delivery bottleneck, major risks, recommended plan, and realistic estimate. If the fit is right, the assessment can lead into ongoing delivery ownership. If your product is delayed, unstable, or difficult to coordinate, send me the current bottleneck, target date, and budget. I’ll tell you whether a Rescue Assessment is the right first step.

You have a product idea, a business problem, or a system that needs to be built right. We've done this 100+ times. AB Ark is a 12-year-old software agency that builds AI-powered web apps, mobile products, SaaS platforms, and enterprise ERP systems — end to end, from discovery to deployment. We don't just write code. We think like product owners. Our team includes BAs, architects, UI/UX designers, and senior engineers who have shipped products across healthcare, fintech, real estate, e-learning, logistics, and more. ━━ What we build ━━ ✦ SaaS platforms & web applications (React, Node, Laravel, Python) ✦ Mobile apps — iOS, Android, Flutter (cross-platform) ✦ AI & automation — ChatGPT integrations, intelligent workflows, ML pipelines ✦ ERP & custom enterprise software — operations, HR, supply chain, finance modules ✦ MVP development — structured 2–4 week sprints with working prototypes ━━ Why clients choose us ━━ ✦ Full BA process — wireframes, user flows, and architecture before a line of code ✦ Fixed-scope or milestone-based contracts — no bill shock ✦ Direct access to senior engineers, not outsourced to juniors ✦ Post-launch support & maintenance included ━━ Tech stack ━━ React.js · Next.js · Node.js · Python · React Native · Swift · Kotlin · AWS · Docker · PostgreSQL · MongoDB · OpenAI API · LangChain If you're evaluating agencies, here's what I suggest: share your project brief and I'll send back a scoped proposal with wireflows and architecture ASAP — at no cost. Let's build something great together.

I build AI systems that take real work off your team's plate — contract review, lead follow-up, customer calls, content, compliance — and ship them in days, not months. Clients typically cut manual hours by half in the first month. PLATFORMS I'VE BUILT → ContractGPT — AI contract analysis with clause extraction, risk scoring, redline-style amendments, and a chat assistant trained on your own documents (Next.js, Claude, Pinecone, Supabase) → Legacy Prime — full construction-management platform: estimating, CRM, field ops, payments, and an AI assistant that logs expenses and books tasks by voice (React Native, tRPC, Stripe, Twilio, OpenAI) → AI Roleplay Training — voice-AI sales coach where reps practice live calls against realistic AI buyers, then get automatic, emotion-aware scoring and feedback (FastAPI, GPT-4, Deepgram, ElevenLabs) → Sales Intelligence Platform — enriches leads, researches accounts, drafts outreach, and runs AI qualification calls so your pipeline fills itself (Airtable, Vapi, n8n, Relevance AI) → AI Content Studio — end-to-end content creation and multi-platform publishing on autopilot (CrewAI, Make, FastAPI, AWS) Also built: an AI lead engine for real estate brokerages, an edtech platform across 8 standardized-exam tracks, a personal-styling AI with computer vision, a family-governance and estate-planning suite, and AI tools for legal, compliance, and healthcare teams. HOW I WORK You don't hand off a brief and wait three months for a black box. I work in fast, live sessions — you describe what you need, watch it take shape, and tell me what to change as I build. This AI-assisted "vibe coding" approach means real, functional software in days, refined until it fits how your business actually runs. WHAT I BUILD AI SaaS platforms with billing, admin dashboards, and role-based access AI agents and copilots (LangChain, CrewAI, custom orchestration) Voice and chat assistants for web, phone, WhatsApp, and Slack Workflow automation across the tools you already use (Make, n8n, Zapier) Full-stack web apps (Next.js, React, FastAPI, Node.js) Mobile apps (React Native, Flutter, Swift, Kotlin) Before AI, I spent 10+ years shipping production software — 25+ mobile apps across the App Store and Play Store, plus dozens of web platforms. So what I build for you is production-grade and built to scale, not a throwaway prototype. RESULTS 40% faster loan approvals with a GPT-4 underwriting integration 60% fewer manual review hours through KYC automation First paying users in 5 days for an AI SaaS MVP On-device ML latency cut from 800ms to 90ms 30% lower infrastructure cost after a serverless migration TECH STACK AI / LLM: OpenAI, Claude, LangChain, CrewAI, LlamaIndex, Pinecone Voice AI: Vapi, ElevenLabs, Deepgram, VoiceFlow Automation: Make, n8n, Zapier Frontend: Next.js, React, React Native, Flutter, Swift, Kotlin Backend: FastAPI, Node.js, Python, GraphQL Cloud & Data: AWS, Vercel, Supabase, Firebase, Docker Tell me what's eating your team's time and I'll tell you how I'd automate it.
