A multi-tenant AI assistant platform, built solo
An AI assistant that qualifies site visitors and hands usable leads to sales, for many businesses at once, without a development project per customer.
Work
Projects
Seventeen years of engineering, from Linux network stacks to AI systems in production. For each project: why it mattered, then how it works.
A hybrid search agent for half-structured questions
Business questions that are half structured data, half free text: an agent that answers both at once, without copying sensitive data out of its platform.
From MVP to an enterprise knowledge-graph platform
Data from disparate legacy systems in one knowledge graph, so search, analytics and new applications plug into one platform instead of each source.
Operator apps that keep customer data inside the platform
The client's team answers conversations and takes over from the bot in a native app, instead of carrying customer data into personal messengers.
An evaluation suite for a lead-qualification bot
Changing a prompt or a model should not be a gamble: simulated visitors talk to the bot, and an LLM judge scores every conversation.
Two AI assistants in production for a digital agency
A first-contact assistant and a subsidy pre-check that tell the agency which leads are worth a call, before anyone at the agency spends time on them.
Three AI agents for a machine builder, tested like software
A product advisor, a knowledge assistant and a service agent that show a manufacturer what AI does with its catalogue, documents and service desk.
Two years of an AI assistant in a beauty studio
From November 2024 an assistant on the website and WhatsApp handled about 70% of client enquiries for a small beauty studio.
Bringing 5G into a mobile network test product
When 5G networks were first being built, operators needed proof that the new implementations follow the standard. The test product had to speak 5G.
A performance-critical message aggregator, delivered as a fast PoC
An extra service for a client, delivered as a proof of concept in a very short time and faster than required by an order of magnitude.
Hundreds of parallel SIP calls from one distributed system
Voice services have to hold up under load. A test system that places and answers hundreds of simultaneous calls, scaled across several hosts.
Search over documents and web pages
Search through PDF documents and web pages inside a product, chosen to fit its constraints and running in production.
An LTE positioning protocol library
A C library for testing location services, implementing the LTE Positioning Protocol straight from the 3GPP ASN.1 specification.
KPIs from network traffic
Network traffic analysis tools extended to extract KPIs for FTP, IGMP, TCP, RTP and other protocols.
1,500 test cases behind an accelerated network stack
A vendor's network acceleration that bypasses the kernel could only ship once it behaved like the real stack. About 1,500 test cases made that provable.
Testing the routing side of an accelerated network stack
Bypassing the kernel for TCP and UDP pulled routing out of the kernel too. About 1,000 test cases proved the new routing before release.
An accelerated network stack inside containers
Containers depend on network interfaces moving between namespaces. Tests proved the accelerated network stack keeps working when they do.
A platform for millions of test results
With thousands of test cases, raw logs stopped answering questions. An internal platform to aggregate and analyse results over years.
An embedded management system for PON networks
An equipment vendor's passive optical network needed a management system of its own: core, SNMP and a command line, embedded and distributed.
A DLNA client to test a home gateway
A UPnP/DLNA client, compatible with MiniDLNA and Twonky, to test the storage and media sharing of a home gateway.
Testing network stacks through the socket API
Network devices, drivers and stacks tested through the BSD socket API: TCP state machine, socket options, multicast, I/O multiplexing.
A distributed test environment
Contributed to the distributed test environment, written in C, that the network test suites run on.
Firmware for a SpaceWire hub
Firmware for a SpaceWire hub, the network standard for onboard spacecraft data, developed in Cadence emulation.
Precise time for SpaceWire networks
The Precision Time Protocol for SpaceWire networks, implemented as a Linux kernel module.
Measuring data transmission on embedded systems
Client-server tools over TCP, UDP and RTP to measure data transmission on embedded systems in SpaceWire and Ethernet networks.
