Built to ship.

Everyday businesses still run on notebooks and chat threads. We replace that with focused products — seven live today — engineered and operated end‑to‑end, from database schema to signed release.

The problem

What we're solving

Three problems we hit repeatedly — each answered by a product that's already live.

Catalogs that drift

Streaming for Asian drama — 4,592 titles, Android and web, offline downloads and episode alerts. Catalog sync, search, and summaries run on Claude.

Operations without a system

Stock in someone's head, debt in a notebook. WarungPintar and HutangGue run offline-first on low-end Android — works with no signal, syncs when it returns.

Software that ships and stays up

Owned end-to-end from schema to signed release: 3 cloud platforms, automated pipelines, monitoring, and zero-downtime migrations.

About

I'm Teguh — founder and builder behind tdsign. Products go from first schema migration to a signed release on the Play Store: design, backend, frontend, and the infrastructure underneath, all owned end-to-end.

Everything here runs on real infrastructure — Oracle Cloud, AWS, and Tencent Cloud — with automated pipelines, monitoring, and zero-downtime migrations.

AI layer

Built with Claude.

Claude models run inside our production products — not as a demo, but as part of daily operations. Every AI feature ships behind the same standard: deterministic fallback, graceful degradation, and user-visible sources.

Semantic search over the catalog

Bluvia's 4,592-title catalog is indexed for meaning, not keywords. Claude reranks retrieval results so a query like “drama Korea tentang balas dendam keluarga” resolves to the right titles — including ones the metadata never spells out.

Synopses that stay on-model

Episode summaries are generated from source metadata and validated against the title's canonical facts before they reach the app. Claude drafts; a deterministic checker rejects anything that invents a character, arc, or episode that doesn't exist.

Operator-side reporting

Internal dashboards turn raw pipeline events into plain-language summaries — what synced, what failed, what drifted — so operations can be run from a phone instead of a SQL console.

Claude Sonnet · structured output · internal tooling

How we integrate. Claude is called through the Messages API with structured outputs and strict schemas. Every AI-backed path has a deterministic fallback: if the model is unavailable, times out, or returns something the schema rejects, the product serves the exact same experience without it. No user-facing surface depends on a model being up.

FAQ

Common questions

How fast can you ship?

Most projects go live in 1-2 weeks. We've shipped API integrations in 48 hours and full web apps in under 7 days. Speed is our default — we work in tight sprints with daily updates.

Do you work with early-stage startups?

Yes — that's our sweet spot. All 6 products we've shipped started as notebook ideas. We help founders go from "I have an idea" to "users are onboarded" in weeks, not months.

What's your tech stack?

We're stack-agnostic but specialize in Python (FastAPI), Flutter, and serverless backends. Heavy Claude API user for semantic search, summarization, and content pipelines. Hosting across AWS, Oracle Cloud, and Tencent for cost + redundancy.

How does Claude fit into your workflow?

Claude powers our semantic layer: catalog enrichment (Bluvia), natural language search, and automated summaries. We've processed 4,500+ drakor titles through Claude's API with sub-second latency. It's our AI brain — we're the execution engine.

What if I only have a rough idea?

Perfect — we start there. First call is 30-minute free product shaping: we map your problem, sketch the MVP, and give you a ballpark timeline + cost. No commitment, no pitch deck needed.
