Problem-driven engineering

Hi, I'm Benny.

Senior Software Engineer | AI Engineering & Software Architecture

I design and build enterprise systems and AI products. With 10+ years of engineering experience, I focus on understanding business problems, choosing practical architecture, and delivering working software.

Previously led engineering teams and delivered enterprise applications across SaaS, finance, consumer services, and mobile platforms, including client projects through Bilue.

Selected work

Products built around real problems.

Selected projects span AI products, connected enterprise workflows, and production software for hotel operations.

AI EngineeringIn development

knowmiii — AI Companion & Core

A local-first AI companion that pairs host-owned memory and provider integrations with a reusable, storage-independent AI Core.

Host applicationCandidate searchJSON memory and SQLite term indexesProvider and device integrations

Reusable AI CoreLLM orchestrationMemory processing; ranks host-selected candidatesContext assembly and contracts

Ownership boundaries · simplified architecture

My role Desktop host and reusable Core engineering.

Engineering decision Start with lightweight local search and keep storage, indexing, and provider integration in the host, so reusable AI processing can evolve with incremental validation.

Engineering details

The Core handles LLM orchestration, memory processing and ranking, and context assembly for host-selected candidates; storage, indexes, and provider integrations stay in the host.
The desktop host stores canonical memory records as JSON and maintains SQLite term indexes with explicit candidate ordering.
Speech-related contracts are reusable Core interfaces; provider credentials and device STT/TTS integrations remain host responsibilities.
Lightweight local search supports incremental validation while leaving room to evolve retrieval with demonstrated needs.

staymiii — AI Hotel Concierge

A multi-tenant hotel concierge where guest and hotel services reuse knowmiii Core context and text streaming over published, hotel-scoped knowledge. Commercial evaluation planned for November 2026, with potential hotel deployment.

Shared Core primitives · hotel backend owns data, retrieval, configuration and providers

My role Guest app, hotel administration, API, and AI service flow.

Engineering decision Reuse storage-independent Core primitives while the hotel backend owns published knowledge, tenant scope, configuration, and persistence.

Engineering details

Guest H5, hotel administration, and tenant APIs form the product layer; retrieval is scoped to the active hotel's published knowledge.
Hotel knowledge is chunked and versioned for publishing; PostgreSQL and pgvector support hotel-scoped retrieval.
The API reuses knowmiii Core context selection and text streaming, and combines guest intent with evidence coverage into a service plan.
Concierge name, tone, prompts, and model selection are configurable; backend token usage and frozen price snapshots support cost tracking.
An STT adapter is implemented; guest voice, TTS, and long-term memory integration are planned.

My role Frontend and backend feature development.

Engineering approach

How I Work

01 / Engineering judgement

Start with the problem.

I clarify the underlying problem, needs, and constraints before choosing a practical approach. I make trade-offs clear and validate assumptions incrementally.

02 / AI-assisted practice

Use AI across the engineering lifecycle.

I use AI for architecture exploration, planning, implementation, and review, choosing models and tools for the task and setting clear agent instructions and boundaries. I review changes, run relevant checks, and remain responsible for engineering decisions, quality, and delivery.

Open source & personal

A few things I've made and enjoy.

Open-source themes and small applications sit alongside my product work. Outside engineering, I enjoy interface design, games, and exploring how digital products feel to use.
