Case studies

Our work, old and new.

This page covers our flagship agentic engagement, the AI-era crews we're running now, and a selection from the .NET and MS SQL era that we still patch every month. We've rebranded, but the track record stands.

WaterDoctor: AI agent stack for biological water treatment

An embedded crew of four agents and two engineers runs adaptive treatment loops on WaterDoctor's biofilm reactors, through the AquaMind agent stack and supporting systems. wGrow is WaterDoctor's strategic technology partner. The work is auditable and readable by regulators, with a weekly release.

Agent output

  1. ingestor.agent sensor batch received
  2. eval.agent no drift against baseline
  3. controller.agent aeration change, inside limits
  4. reporter.agent figures linked to raw data
  5. controller.agent proposed change over 15% of baseline
  6. engineer approval requested, change held
The live loop, illustrated: any change more than 15% from the rolling baseline waits for human approval.

AI-era engagements

Newer crews, under the same delivery rules.

Alongside WaterDoctor, these are three engagements where the deliverable is an agent or a fine-tuned model running in production.

  • Live, private LLM

    Private LLM for TV-script production

    An embedded engagement with an overseas television-series studio. We fine-tuned a DeepSeek base model on the studio's 3,000+ in-house scripts and shipped a private, on-prem LLM for their writers' room, calibrated to house voice, format and continuity.

  • Live, internal, open-source sample

    Server-ops agents on Claude Code

    Internal crews built on Claude Code for server management, covering log triage, deployment runs and incident commentary, inside a private, hardened Telegram bot. The reference architecture is open-sourced as ClaudeAgentBOT, so buyers can evaluate the pattern before they engage.

  • Live, gen-AI pipelines

    eCommerce product generation: image and video

    Generative pipelines for product research and listing content: image variants, lifestyle stills, and short-form video for marketplaces and ad creative. We use them in our own commerce R&D and on selected eCommerce engagements where speed to creative is the bottleneck.

From the longer book

Eighteen years of systems we still patch.

Healthcare, legal, government, finance, eCommerce, manufacturing and infrastructure. Most are still running. Here is a selection, and the full archive is on its own page.

  • Healthcare, AWS

    Patient Management System

    A multi-clinic patient and medical records platform, covering appointment scheduling, lab integration, drug inventory and billing, with field-level encryption and audit trails. Still in production.

  • Government, grants

    Grants Management System

    End-to-end grants administration for a Singapore grant-making body, with an applicant portal, expert review, claims handling and procurement-grade audit controls.

    .NET, MS SQL, audit logs, PDPA

    Grant-making body

  • eCommerce, named

    Vitasg.SG: health supplements

    An end-to-end commerce stack for Singapore-based Vitasg.SG, with Shopee and Lazada integration and regional expansion into Malaysia and Indonesia.

  • Infrastructure, SS 564

    Green Data Centre Reports

    SS 564 certificate reporting for a data-centre operator, with IoT sensor ingest, PUE calculations and automated submission packs that stand up to an audit.
