TradeWeave, and the person behind it
TradeWeave is two things at once: a public, server-rendered analytics platform over a primary-data Parquet corpus, and the research backbone for professional engagements led by Md Deluair Hossen, PhD. The open pages and the client work share one codebase, one data layer, and one standard of evidence.
What the platform is for
Public-good open trade analytics. Every analytical page on this site is free to read, free of login and paywall, and reproducible from the Parquet corpus and the embedded SQL. Sources are open or free-for-research with attribution. The JSON API endpoints and the read-only SQL console are public. The point is a serious reference that any researcher, journalist, student, or policymaker can use without a contract.
Underlying infrastructure for professional engagements. The same Parquet tables, DuckDB query layer, and estimator library that power the public pages are the substrate for consulting work: tariff scenarios, market-entry diagnostics, supply-chain exposure audits, country risk notes, and bespoke econometric analysis. Clients get findings grounded in the same primary sources the public site cites, not a black-box dashboard.
A live workbench for researchers. New methods and new data releases are wired in as they land. A page is not a static deliverable; it is a view on the current Parquet snapshot. That means the workbench doubles as a development environment for applied trade research, with every figure reproducible end-to-end and every estimator cited to the paper behind it.
What this platform is
TradeWeave Workbench is a server-rendered analytical site over a ~1.4 GB ZSTD-Parquet corpus of primary trade and macro data (CEPII BACI, CEPII Gravity, CEPII TRADHIST, IMF BoP/WEO/IFS/IIP, World Bank WDI and Pink Sheet, FAOSTAT, WITS/TRAINS, WTO/UNCTAD NTMs, OECD TiVA, ESCAP, FRED, BLS). Each page answers one question with figures wired directly to DuckDB queries and cites the paper behind every method: DiD event studies, PPML gravity, Hausmann-Hidalgo complexity, Schott-Khandelwal quality ladders, Novy inverted-gravity trade costs, Antràs-Chor upstreamness, Finger-Kreinin similarity, Imbs-Wacziarg diversification.
It is not a dashboard. Each analytical page embeds the SQL that produced every figure, so a reader can audit the number, re-run the query, and cross-check the method against the cited paper. Charts are server-rendered SVG; there is no client-side chart library for most pages, so the site loads under 100 ms on a warm Parquet cache.
How it differs from published platforms
The Harvard Growth Lab's Atlas of Economic Complexity and the Observatory of Economic Complexity (OEC) are excellent visual explorers of the same underlying BACI corpus, but neither exposes the SQL, the Parquet files, or the literature the estimator is from. This workbench makes all three visible on every page. It also extends the corpus beyond BACI into IMF BoP/IIP, CEPII TRADHIST (1827-2014), ESCAP trade costs, OECD TiVA, and WITS tariffs, and runs its own ECI/PCI, RCA, HHI, proximity, trade-cost, and upstreamness computations rather than re-using pre-rendered aggregates. It is a research workbench, not a visualization product.
Work with us
The same infrastructure that powers the public pages is available for commissioned work: tariff and trade-policy scenarios, country and sector diagnostics, supply-chain and concentration audits, custom econometric analysis, and one-off data pulls from the Parquet corpus.

Open-data commitment
Every source on the public site is open or free-for-research with attribution. Every figure is reproducible from the Parquet files and the embedded SQL. There is no login, no paywall, no analytics tracker behind the charts. Client work uses the same corpus and the same methods; the deliverables are private, the tooling is not.
