Relocate: No. Web and mobile developer. I ship products on my own, from architecture to production. GPI France (medical software, on-premises with no internet access): built KeyMaster, a Django/Angular licence manager that replaced a third-party product. ECDSA-signed keys let a hospital validate its licence offline. Django and Angular were both new to me on arrival. Working hours are 09:00-18:00 Paris, i.e.…

Relocate: No. Looking for a remote senior software engineering role or DevOps that is still engineering. Remote senior software engineer, 20+ years. Last year was DevOps (Azure, AWS, Kubernetes, Terraform); I still write as much code as ever. I write programs that write programs. Data UI is a compiler: a 57-line model becomes PostgreSQL, REST, React, row-level RBAC, and a Kubernetes+TLS deploy, versus roughly 20,000…
Relocate: No. I mostly work on production AI agents: the data and context they run on, the orchestration, and the evals that catch the agent when it does something dumb. That last part is the half most people skip, and it is usually the reason the thing survives a real user. A few specifics: - Co-founded Cozmoz, an agent that drives any mobile app from vision alone, no selectors. I built the eval and observability…
HN user awakmeuleuweuk · Jakarta, Indonesia (UTC+7)
Relocate: Yes for the right role (would need visa sponsorship). I rebuild pipelines other people have stopped looking at. Current problem, my favourite kind: SCADA time series for renewable assets. One asset's backfill alone is ~758 series and 13M rows, and it pushed a Postgres instance from 8 GB to 16 GB before hitting a storage cooldown; a few assets of that is multi-TB a year. So I'm designing the warm/cold split…

HN user jorbach · Tel Aviv, Israel (UTC+3, European working hours)
Relocate: Open to it. Full-stack engineer, 4+ years, looking for a steady full-time role: full-stack, solutions/support engineering, or SDK/integrations work at a remote-first company. I've shipped two products solo to paying users: GhostChat (ghostchat.dev), a 15KB dependency-free chat SDK with a production Claude assistant, live on ~190 sites; and Gmailytics (gmailytics.com), Google CASA Tier 2 certified, 5M+…

I own the financial backend end-to-end: payment infrastructure across 7 rails (Stripe, M-Pesa, Basis Theory, direct bank APIs), serving hundreds of thousands of users in Kenya and Tanzania. On the side I built Watchdock, an observability platform that processes 25M+ nginx logs and generates AI-powered incident…
Relocate: No. Senior/staff backend & systems engineer. I design, build, and own backend services and data models end to end, and go as deep as the system needs - down to production infra and build tooling (recent: GCP VM→Kubernetes and CI/CD unification). At my best designing systems for the failure modes most people only meet in production, and building the tooling that makes a whole team faster. Full-stack when a…
