    (JAKARTA, INDONESIA)

    PRACTICAL AIFOR BUSINESS.

    I help companies put AI to work. Building AI agents, training teams, and turning AI into real results without the hype.

    CURRENT FOCUS

    Going deep on AI agent reliability and evaluation, the real gap between a demo that works and an agent a business can trust in production.

    (Who I work with)

    Teams I've trained and worked with

    Directly, and through the companies I co-founded: Infused (AI agent builds, with its corporate-training brand Latih AI) and Epilog Creative (digital agency).

    (BUILD GUIDE / Q2 2026)

    Building AI agents that actually hold up

    The field manual I actually build from: the decision gate, the seven-layer architecture, evals, guardrails, and the discipline behind agents that survive production. Anti-hype, grounded in real reports.

    Read the build guide
    • The decision gate: most agent ideas should die here
    • The seven-layer architecture
    • Evals as the product, not overhead
    • The three tiers, personal to enterprise
    • Stack: OpenRouter, Supabase, Pydantic AI, n8n, Langfuse

    (WHO)

    Hi, I'm Abi

    I co-founded and run Epilog Creative, an established Jakarta digital agency working with brands like BCA, BSI, Bayer, and Brompton, and I build AI agents through Infused. I also train teams to use AI and help leaders figure out where it actually fits. I am not an engineer. I look at AI from the business side, which is the part most people get stuck on.

    Everything I share here comes from real work, not theory. I write it down so you can skip the part where you start from zero.

    Tools and articles worth your time

    See more

    The AI tools and articles I find genuinely useful and think you should see too.

    Dust

    AI agents that actually know your company, connected to Slack, Notion, Drive, and Salesforce, with permissions that separate what an agent can see from who can run it. This is the shape most useful internal agents take, not a clever demo but one wired into the real knowledge and the real guardrails.

    dust.tt
    Vapi

    Infrastructure for voice agents that answer and make real phone calls. You bring the model and telephony, it handles the listen-think-speak loop, the latency, and the monitoring. Worth knowing when the job is literally on the phone, like inbound support or outbound follow-ups.

    vapi.ai
    Langfuse

    Open-source observability and evals for AI apps: traces, prompt versions, cost, and scoring across real runs. This is how you tell whether an agent is genuinely reliable or just lucky in the demo. Part of the stack I actually build on.

    langfuse.com
    Microsoft Copilot Studio

    The low-code way to build agents if your company already lives in Microsoft 365. Not the most flexible option, but sitting next to Teams, SharePoint, and the existing governance is often exactly what gets an agent past IT and into real use.

    microsoft.com
    Gumloop

    No-code, drag-and-drop AI automations and agents for people who are not engineers. Think of it near n8n and Make, with a gentler on-ramp. Good for letting a business team build its own small agents instead of queuing behind the dev backlog.
