Mah S.
Fractional CTO & Software Architect | AI Agents, Python, Next.js
I am a Fractional CTO and Software Architect. Clients usually hire me for one project, whether an audit, an automation build, or a stalled project, and keep me on because I take ownership of their technology month after month so they never have to think about it again. With 8+ years across startups and SMEs, I act as the long-term technology partner for businesses in logistics, B2B fintech, and operations-heavy industries. I work out what the business needs, build it, and keep it running for a monthly fee instead of a full-time hire. HOW I WORK WITH CLIENTS 1. Systems & AI Opportunity Audit (Fixed-Price Entry Point) I review your operations, APIs, and existing codebase (Python, Node.js, Next.js, React) and deliver a prioritized roadmap. I show you where you are losing time and money, which vendor quotes are bloated, and what things should actually cost. You get clarity before committing to a larger build. 2. Ongoing Fractional CTO (Monthly) For clients who want ongoing ownership, I handle architecture decisions, vendor management and risk control, developer management, and budgeting. Every task is fully scoped before work starts, so you get no scope creep and no budget surprises, just systematic, stable delivery. 3. AI Agents & Workflow Automation I do not pitch abstract AI initiatives that consume your management time. Tell me which process eats the most staff hours (manual reporting, re-keying data between systems, customer replies) and I build the automation that removes it. This includes custom AI agents, LLM/RAG pipelines, business process automation (RPA), and internal tools that run inside your own systems. Recent example: replaced a client's manual overnight reporting with real-time CRM synchronization. The report that used to need a graveyard shift now updates itself. 4. SaaS & MVP Development When something needs building from zero, I build it to still be maintainable years later using Python (FastAPI/Django) and Next.js, with auth, payments, the admin panel, and production deployment included. Everything lives in accounts you own (your repository, your cloud, your data) on standard, widely-supported stacks. If we ever part ways, any competent developer can pick it up the next day. WHY CLIENTS STAY Business-first: I prioritize operational ROI over flashy features. Direct: you work with me, not an account manager, and not a team you have never met. Proven: Top Rated Plus, 100% Job Success, and clients who came for one project and stayed. My longest client relationships run for years, on and off Upwork. Check my work history. LOCATION, LANGUAGES & TIME ZONES I am based in Malaysia (GMT+8) and work with clients across the US, Australia, and Asia. For US clients, the time difference works in your favor. Brief me at the end of your day and the work is ready by your morning, and I keep my mornings open for calls during your evening. For Australia and Singapore, we are in the same working hours. I respond fast, usually within a few hours (my profile stats show it). I work in English daily and am also a native Chinese speaker (plus Malay), which is highly useful if your business touches Chinese-speaking suppliers, APAC customers, or Southeast Asian markets. Start with a diagnostic audit, or invite me to your job and share your goal, timeline, and budget range.
