I am a skilled Backend Engineer with two years of hands-on experience in building and optimizing robust server-side applications. My background includes working with a diverse range of clients, where I've developed solutions that enhance performance and reliability. I specialize in streamlining backend processes, ensuring scalable and efficient systems. My experience includes roles at tech-forward companies and participation in impactful internships, equipping me with a solid foundation in programming and risk assurance. If you're seeking a detail-oriented freelance engineer who can transform your ideas into effective solutions, let's discuss how I can help elevate your project to the next level.

Are you a non-technical founder or business owner with a clear vision, but no desire to manage a dev team? As a Fractional CTO and Lead Architect with 15+ years of experience, I take your software from napkin sketch to live production. I operate at the intersection of senior engineering and executive technical leadership. My role is to act as your "Tech-to-Business Translator" - converting your commercial objectives into scalable, high-performance architecture without the confusing jargon, giving you absolute visibility over your product. I leverage advanced AI tooling and strict architectural standards as a development force multiplier. This means you get the execution speed, output, and reliability of a full engineering team through a single, highly accountable expert. No coordination overhead. No junior-dev babysitting. No technical black boxes. THE TERMS OF ENGAGEMENT: * The 14-Day Mutual Alignment Guarantee: Software architecture requires absolute trust. If you are not completely satisfied with my execution, or if our communication styles do not perfectly align within the first two weeks, I issue a 100% refund, no questions asked. * Async-First Execution: I protect your budget by protecting my focus. We hold one highly structured weekly alignment call to review progress. All daily communication and updates are handled asynchronously via text or Loom video. You pay for engineering throughput, not meeting bloat. * Clean Handoff & IP Sovereignty: You hold the root infrastructure keys and own 100% of the source code and intellectual property from day one. No proprietary vendor lock-in. * 30-Day Code Warranty: I stand by my architecture. I patch any bugs within the delivered scope for free for 30 days post-launch. WHAT I ARCHITECT & DELIVER: * Core SaaS MVP Development: Lean, zero-dependency, hyper-fast systems designed for rapid market validation. * Deterministic AI Integrations: Production-grade LLM pipelines, autonomous subagents, and secure RAG systems built to eliminate hallucination risks. * Bulletproof Backend APIs: Robust, highly secure data layers and infrastructure designed to support complex web and mobile frontends. * High-Efficiency Infrastructure: Cost-effective self-hosted deployments (Hetzner, Docker, Traefik) that keep your ongoing server overhead near zero. LIFETIME PERFORMANCE METRICS: * Upwork Expert-Vetted Status (Top 1% of historical talent on the platform) * $395K+ earned across 100% Job Success software deployments * Over 80+ completed projects with zero hourly-tracking friction * Founder of NeatSoft PTE LTD (Singapore corporate entity) If you need an autonomous technical partner to take complete ownership of your engineering pipeline, send me a message describing your core business objective. I will respond with a clear, jargon-free technical path forward. --------- Core Tech Stack & Search Keywords: Fractional CTO, Software Architecture, SaaS MVP Development, TypeScript, Deno, Preact, Hono.js, SSR Fresh, REST API Development, Backend Architecture, PostgreSQL, Valkey, Docker Compose, Traefik, Hetzner Dedicated Servers, Self-Hosted Infrastructure, PWA, React, Next.js, Tailwind CSS, Node.js, Express.js, Firebase, Supabase, Generative AI, Large Language Models, LLM Pipelines, DeepSeek, Claude 3.5, OpenAI API, RAG, Vector Databases, Prompt Engineering, System Performance Optimization, Web Security, CI/CD, API Integration, Stripe, Algolia, Twilio.

Most organisations don’t actually need “AI features”. They need systems that understand how their organisation works and help it run better. I design and build AI-driven operational systems that connect data, workflows, and decision-making across a business. These systems often combine knowledge engines, automation pipelines, and multi-agent AI architectures to solve real operational problems. Clients typically come to me when they are dealing with things like: • spreadsheets that have grown into fragile operational systems • manual processes that are slowing teams down • complex data that nobody can properly interrogate • internal knowledge scattered across documents and tools • AI initiatives that feel exciting but lack real operational impact My role is to understand the problem, design the system, and then build or orchestrate the solution. ⸻ What I Build Examples of the kinds of systems I design and implement: AI Knowledge Systems Upload internal documents and data, and allow teams to query how the business actually works. Operational AI Automation AI systems that connect workflows, decisions, and operational processes. Multi-Agent AI Architectures Systems where specialised agents collaborate to analyse information, generate outputs, and improve processes. Document Intelligence Pipelines OCR, structured extraction, validation layers, and automated analysis of large operational datasets. Operational Platforms Internal tools and dashboards that allow teams to manage complex workflows more effectively. ⸻ How I Work My background is unusual for a developer. Before moving into software full-time, I founded and scaled businesses to over $20M in annual revenue. That experience shapes how I approach every project. I think in terms of: • operations • incentives • information flow • decision points • system bottlenecks Technology only comes after the architecture makes sense. Clients often describe my role as somewhere between: • AI architect • systems designer • technical product strategist ⸻ Example Systems I’ve Built Procurement Optimisation Platform Automated supplier pricing comparison across multiple vendors, reducing purchasing costs by 15%. AI Knowledge Engine Upload company documents and allow teams to query how their organisation works. Scheduling & Operations Platform (Charity Sector) Replaced spreadsheets and messaging groups with a structured system coordinating volunteers and appointments. Document Processing Pipelines Automated extraction and analysis of supplier data from complex documents. ⸻ Technology I use whatever tools best suit the architecture, including: OpenAI / LLM systems vector search & embeddings API-driven architectures automation pipelines Supabase / Vercel environments Bubble and rapid application platforms where appropriate But the real value I bring is system design, not a particular tool. ⸻ If You’re Looking For • AI systems that actually solve operational problems • a knowledge engine for your organisation • automation that replaces manual processes • a multi-agent AI architecture • someone who can translate business problems into working systems then I’d be happy to talk.
