Hire the Best Engineering Freelancers in Singapore, SG

Hi! Valent here, part-time freelancer. I am a Mechanical/R&D Engineer with more than 5 years of SolidWorks/Fusion 360 and Product Design experience, particularly in medical devices with ample knowledge in ISO and IEC standards. Skilled in SolidWorks. I can create precise CAD models and drawings that are ready for manufacturing from your sketches and concepts. My skills are: - Creating 2D CAD Drawings and 3D CAD models from hand sketches, photos, dimensioned drawings or AI-generated concepts. - Reverse engineering and modifying CAD models. - Creating Parametric Assemblies while applying GD&T. Hire me as your 3D CAD Designer for precise, manufacturing and professional results.

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.

Are you tired of hiring a web developer who doesn't understand marketing, and a media buyer who complains your website doesn't convert? To scale a business today, you need all the pieces to work together perfectly: a rock-solid market strategy, a high-converting website, and highly targeted traffic. That is exactly what I build for my clients. I am a Hybrid Digital Professional—part business strategist, part web developer, and part media buyer. I don't just run ads or write code in a vacuum; I engineer end-to-end growth systems designed to capture market share and drive revenue. Here is how I can help you scale: Business Growth & Market Positioning: Before we spend a dime on ads or write a line of code, we need a plan. I will help you define your target audience, analyze your competitors, and create a positioning strategy that makes your offer a no-brainer for your market. Web Development (The Conversion Engine): I build fast, responsive, and beautiful websites. But more importantly, I build websites engineered to convert traffic into paying customers or qualified leads. Traffic Generation (Meta & Google Ads): Once the foundation is set, I design, manage, and relentlessly optimize your paid acquisition campaigns across Meta (Facebook/Instagram) and Google Ads to bring high-intent buyers straight to your door. Transparent Reporting & Insights: You will never be left in the dark. Once campaigns are running or concluded, I break down the traffic, conversion data, and overall campaign progress in clear, jargon-free reports. We will regularly discuss these results together so you always know exactly what is working, where your budget is going, and what our next strategic move will be. Why work with me? Because I see the big picture. When your ads, your website, and your business strategy are all managed by the same brain, your Customer Acquisition Cost (CAC) goes down, and your return on investment goes up. No more playing telephone between different freelancers. Whether you are launching a new brand and need the entire digital infrastructure built from scratch, or you have an existing business that has hit a revenue plateau, I can help you break through. Send me a message with a brief overview of your current business goals. Let's discuss how we can engineer the next stage of your growth, aiming for a minimum of 20% ROI within the first month.
