Professional summary

I combine water-domain knowledge with software engineering to build internal platforms, SDKs, APIs, simulation workflows, and decision-support tools for infrastructure teams. Several are now in daily use across teams. Recent work spans digital-twin concepts for drinking-water treatment and distribution, internal Python SDKs adopted across a growing data team, governed adoption of generative AI, and PHREEQC/EPANET-oriented simulation workflows. I also coach engineers and help data teams turn prototypes into software they can support.

Selected systems & capabilities

Internal platforms

From operational problem to supportable internal capability: data model, API, validation, user workflow, documentation, deployment path, and handoff to managed platforms.

Internal Python SDKs & data foundations

Python SDKs that standardize data access, wrap APIs, encode domain logic, and give teams a shared interface for analytics, automation, and internal software.

Simulation & scenario workflows

Python/API integration patterns for water-domain solvers such as PHREEQC and EPANET, with attention to assumptions, validation, reproducibility, and decision support.

Governed AI adoption

Early LLM experimentation, multidisciplinary exploration, management briefings, Copilot rollout input, responsible-use guidance, and AI-assisted engineering patterns.

  • Develop digital-twin concepts for drinking-water treatment and distribution, translating telemetry, lab context, scenarios, replay, reporting, and validation needs into inspectable software workflows
  • Create and maintain internal Python SDKs that standardize data access, wrap APIs, and encode reusable domain logic, now a shared foundation adopted across a growing data team for analytics, automation, and internal tools
  • Build internal applications and services with FastAPI, React/Next.js, TypeScript, SQL, Azure services, Docker, CI/CD, authentication patterns, documentation, and Power BI where operational reporting fits
  • Work on Python-based integration patterns for domain solvers such as PHREEQC and EPANET, connecting scientific models to web-based scenario and decision-support workflows
  • Turn ambiguous, cross-team operational questions into data products that make assumptions, data quality, and decisions visible. Several are now in daily use across teams and credited with meaningful time savings, including work delivered in-house instead of outsourced
  • Help mature data-science delivery practices through code review, typed interfaces, modular project structure, documentation, deployment discipline, Agile working methods, and handoff paths to managed platforms
  • Shape governed AI adoption through early LLM experimentation, multidisciplinary exploration, ChatGPT/Copilot pilots, management briefings, responsible-use input, and AI-assisted engineering patterns
  • Coach junior data scientists and data professionals, contribute heavily to recruiting and onboarding as the data team grew, and act as a practical bridge between domain experts, data-platform teams, software delivery, and leadership

MSc Water Management

For our thesis, we travelled to Bandung, Indonesia, to improve the water treatment process at PDAM Tirtawening. We discovered that performance issues weren't due to one major fault but many small ones, like broken metering equipment and poor coagulant dosing. By introducing a few simple changes, we reduced turbidity by over 60%. The real fix wasn't expensive equipment, but better understanding and maintenance. Presenting our findings to the plant's director was a proud and eye-opening moment.
