Andrew is the best possible thing to happen to our business and the definition of a true professional. I could not recommend him enough. Anyone who has the opportunity to work with Andrew should consider themselves extremely lucky. โž I excel at expertly guiding the app dev process to max out your revenue-earning potential in contrast to your costs, and to steer you away from common SaaS app pitfalls. Client Outcome Examples: โšก amzalert.com (8-Figure Acquisition - Rebuilt In 4 Months) โšก launchcontrol.us (8-Figure Annual Recurring Revenue - ARR) โšก GuestBan.com (Concept-To-Live in 5 Months - 1M+ Monthly App Checkins) My support is based on hard-won successes built through more than a decade of SaaS app obsession. Most of my clients are: โ˜‘๏ธ Existing Businesses - Post-revenue โ˜‘๏ธ Solopreneurs & Small Teams - Wanting to build an MVP app โ˜‘๏ธ Funded Startups - Focused on turning funding into MRR โ˜‘๏ธ Existing Early Stage SaaS - Want to rebuild and scale up Iโ€™m the founder of a small, hand-picked team of talented humans. Iโ€™m personally involved in all projects, and we only employ senior developers and native English speakers from the US for project management and communication. My team and I are able to consistently reduce dev costs by about 30-40% by leveraging pre-built development frameworks for common app experiences like the user login or checkout, for example, while reserving valuable dev hours for truly custom functionality. Every project we build delivers: ๐Ÿ“ฑCross Device Compatibility - Desktop - Mobile - Tablet ๐Ÿ“ˆ App Speed Optimization ๐Ÿงฉ Scaleable - Cost-Effective Feature Addition Potential ๐Ÿ›ก๏ธ Security ๐Ÿ“Š User Analytics & Internal Dashboards ๐ŸŒ Multi-Language Localization ๐Ÿค– Quality Assurance - QA ๐Ÿ“œ Paid User Subscription, Billing & Renewal Management Thanks for taking the time to learn more about me.

OSCP & CREST-certified Penetration Tester helping SaaS companies, startups, e-commerce platforms, and enterprise teams find real, exploitable security weaknesses before attackers do. I provide manual-first penetration testing for Web Applications, APIs, Mobile Apps, Networks, Active Directory environments, Infrastructure, and Thick Client/Desktop Applications.

I built my first Voice AI agent 24 months ago. It worked perfectly in testing. Then a caller with a heavy accent asked a question while their dog barked in the background, and the whole thing collapsed. That project taught me something most AI developers learn too late: the demo is 10% of the work. The other 90% is everything that can go wrong - bad audio, CRM timeouts, users who say "um" fourteen times, edge cases nobody warned you about. Now I only build AI that handles the chaos. ๐—ช๐—ต๐—ฎ๐˜ ๐—œ'๐˜ƒ๐—ฒ ๐—ฏ๐˜‚๐—ถ๐—น๐˜ ๐—ค๐—ฎ๐—น๐—ถ๐—ณ๐—”๐—œ takes 40+ real estate calls daily.

I help startups and growing businesses stabilise, improve, and ship digital products โ€” especially platforms built with AI tools, low-code workflows, and vibe-coded apps on platforms like Replit. If you have a product that was built fast and now needs to be fixed, cleaned up, extended, or made reliable for real users, thatโ€™s where I come in. I work with founders and teams to turn fragile MVPs into usable, scalable products by improving UX, fixing broken flows, refining the product strategy, and helping engineering move faster with less chaos. What I can help you with โ€ข Stabilising platforms built on Replit, AI app builders, low-code tools, and vibe-coded workflows โ€ข Improving broken or confusing user journeys โ€ข Turning rough prototypes into production-ready product experiences โ€ข Designing and shipping SaaS platforms, internal tools, dashboards, and client-facing apps โ€ข Adding AI features that are actually useful to users โ€ข Scoping MVPs, prioritising features, and reducing product risk โ€ข Leading product execution from idea to launch What clients hire me for โ€ข Platform rescue: fixing products that were built quickly but are now unstable, messy, or hard to maintain โ€ข UX + product improvement: making apps easier to use, clearer, and more likely to convert โ€ข Rapid prototyping: building and testing new features quickly before teams overinvest โ€ข AI workflow implementation: integrating OpenAI, automation tools, and smart product experiences into existing platforms โ€ข Founder support: helping non-technical or overstretched teams make better product decisions My approach I donโ€™t just make screens look better or build random features. I help clients figure out what is breaking, what matters most, and what needs to happen next to make the product more reliable and more valuable. That might mean: โ€ข auditing the product and identifying friction points โ€ข redesigning key flows โ€ข improving onboarding and conversion โ€ข cleaning up the product structure โ€ข working with developers to implement better solutions โ€ข using tools like Replit, Figma, React, Laravel, Supabase, n8n, OpenAI, and payment integrations to move quickly Types of projects Iโ€™m a strong fit for โ€ข Startups with an MVP that feels unstable or unfinished โ€ข Founders who built fast with AI tools and now need product structure โ€ข Teams that need a UX/product partner who also understands implementation โ€ข Businesses adding AI features, automation, or new digital services โ€ข Companies that need someone to bridge strategy, design, and delivery If your app was built quickly and now needs to be stabilised, improved, or prepared for growth, I can help you get it there.

I help founders, SaaS teams, and business owners turn AI ideas into clear product, architecture, and implementation plans. If you are planning an AI chatbot, RAG system, AI agent, AI copilot, OpenAI/Claude/Gemini integration, or AI-enabled SaaS feature, I can help you decide what to build, what to avoid, and how to move toward a production-ready solution. I have 15+ years of experience across software architecture, SaaS development, API integration, cloud systems, and product delivery. I usually work with clients before or during development to bring clarity around the right AI approach, MVP scope, architecture, timeline, risks, and execution plan. I can help with: - AI integration strategy for SaaS products and web applications - RAG architecture for document, knowledge base, and internal search systems - AI chatbot, AI assistant, and AI copilot planning - AI agent and multi-agent workflow design - OpenAI, Claude, Gemini, Cursor, LangChain, and LlamaIndex solution planning - AI-powered document processing, summarization, search, and reporting - SaaS architecture, API integration planning, and cloud readiness review - AI MVP scoping, technical roadmap, and development team guidance Clients usually come to me when they need answers to questions like: 1. Can AI actually solve this product or business problem? 2. Should this be a chatbot, RAG system, AI agent, copilot, or simpler AI feature? 3. How do we connect AI with our SaaS product, database, CRM, internal tools, or APIs? 4. How do we reduce hallucinations and unreliable AI responses? 5. What should be included in the first MVP? 6. What will it take to build this securely, scalably, and cost-effectively? My focus is not โ€œadding AIโ€ just because it sounds good. My focus is helping clients build AI features that solve real product, workflow, and business problems. Relevant areas I can help plan: 1) AI Integration for SaaS Products - AI search, AI assistants, AI copilots, automated summaries, smart recommendations, document analysis, reporting workflows, and backend AI features for SaaS products and internal platforms. 2) RAG Systems and Knowledge Assistants - RAG architecture for products that need to answer from documents, PDFs, websites, customer records, internal knowledge bases, or structured business data. 3) AI Chatbots and AI Agents - Planning chatbot and agent workflows with conversation flow, role-based access, admin controls, escalation logic, backend integration, API actions, and human review where needed. Tools and technologies I work around include OpenAI, ChatGPT, Claude, Gemini, LangChain, LlamaIndex, RAG, vector databases, Pinecone, Weaviate, Chroma, Supabase, Python, FastAPI, Django, Node.js, React, Next.js, REST APIs, SaaS architecture, AWS, Azure, Google Cloud, API integrations, CRM/ERP integrations, n8n, Make, and Zapier-style automation. I bring both technical and business understanding. I can work with founders, product owners, CTOs, business teams, and developers to convert an idea into a clear technical direction. When needed, I can also support execution through Citrusbug/Aitiateโ€™s AI and SaaS engineering team.
