Teams and other profiles
TECHVIEW is not one pair of hands. A role that needs a team gets engineers it has shipped production systems beside and vouches for by name, and if the profile you need is not this one, say so and it goes looking rather than bending a CV to fit.

Experience
Senior engineer with eight years of production software across fintech, rail, telecom, and enterprise platforms, the last three as founder of TECHVIEW. Python, Node.js, Go, and .NET are the daily languages, on retrieval systems, inference services, and the pipelines that carry them. Comfortable owning a system end to end, architecture to operations, or joining a Scrum team that already has one.
- Applied AI
- In production for two companies: hybrid retrieval on pgvector and Postgres full text search, with chunking, metadata filtering, and reranking, MCP servers and tool calling, and streaming or one-shot endpoints picked per task on cost and latency. Agent work in LangChain, LangGraph, Semantic Kernel, Microsoft Foundry, and the M365 Agents SDK, with deterministic code kept wherever it beats a model.
- AI evaluation and quality
- Benchmark suites over public corpora, MIDV-2020 and SmartDoc among them, with declared baselines, per-metric tolerances, and an exit code that makes a quality regression a red build. On LLM output: retrieval relevance scored against human review, hallucinated fields cross-checked against the source catalogue, omission rates tracked per field over 90 days, and traces in PostHog and OpenTelemetry.
- Backend and cloud-native
- Python, Node.js, Go, and .NET services behind REST, gRPC, and GraphQL, on Kubernetes and Terraform across Azure, AWS, and GCP, with CI/CD in GitHub Actions and ArgoCD, secrets in Vault, and Sentry, OpenTelemetry, and Datadog wired in from the start.
- Regulated and security-sensitive
- A core banking platform built from scratch, on PSD2, PCI DSS, and ISO 20022, with KYC, KYB, AML, sanctions and PEP screening, and transaction monitoring, identity on OAuth 2.0 and OIDC, and an engineering portal hardened alongside a national rail operator's teams.

Track record
- 2023-TECHVIEWFounder and lead software engineer. A core banking platform built from scratch for a European fintech, with SEPA and card rails, identity, KYC, KYB, AML, and fraud screening around it. An engineering portal for a rail manufacturer, hardened, extended, and maintained alongside the national operator's teams. An enterprise design system in Angular microfrontends on dozens of live applications, with an MCP documentation server over ChromaDB and agents in Semantic Kernel, Microsoft Foundry, and the M365 Agents SDK, and integration work in Java with the platform's back end engineers. Its own products Geosignal, Roadsignal.be, and HUMP.ae all live, their RAG brains on pgvector and Postgres full text search, prototyped and benchmarked in LangChain and LangGraph, with stateless Python inference behind gRPC and each release gated on measured quality.Missions in this period
