    tommythorn/Reduceron★ 461 · ⑂ 35

    FPGA Haskell machine with game changing performance. Reduceron is Matthew Naylor, Colin Runciman and Jason Reich's high performance FPGA softcore for running lazy functional programs, including hardware garbage collection. Reduceron has been implemented on various FPGAs with clock frequency ranging from 60 to 150 MHz depending on the FPGA. A high degree of parallelism allows Reduceron to implement graph evaluation very efficiently. This fork aims to continue development on this, with a view to practical applications. Comments, questions, etc are welcome.

Find Haskell engineers shipping Compilers

The list above ranks the most-starred public Haskell repositories tagged with the Compilers topic, drawn from the public GitHub graph. Across 53 matching repositories, the contributors are a tight cluster of engineers with both Haskell chops and real Compilers experience.

That overlap is rare. Most Haskell engineers haven’t shipped Compilers, and most Compilers maintainers don’t write Haskell. The people on this list’s contributor graph are the ones who do both.

Refolk turns this list into a search. Ask for “Haskell Compilers maintainers hiring” or “Haskell engineers shipping Compilers in 2025” and Refolk returns a ranked shortlist with the commits, profiles, and projects behind each name.

How this list is built

Refolk searched GitHub for public Haskell repositories tagged with the Compilers topic, ranked them by stargazer count, and kept those with at least 25 stars. The list refreshes once a day.

Common questions

How are these repositories ranked?

By stars, with forks and recent activity as tiebreakers, read from the public GitHub API. The methodology section above has the details.

How fresh is the data?

The ranking re-renders at least daily. Last refreshed: Sun, 20 Sep 2026 23:21:20 GMT.

Can I find the maintainers and contributors behind these repos?

Yes. Stars rank the projects; I can rank the engineers - maintainers, top contributors, and the people they work with. You start with 500 free credits, no card required.

Can I use this list for hiring?

That's the point. I read hiring signals across GitHub, LinkedIn, and the open web, so a repo list turns into a shortlist of engineers worth talking to.

Try it on the search you came here for

Stop building boolean strings. Just describe the person.

Type one sentence. I plan the search, read GitHub, public LinkedIn and Crunchbase records, and the open web as it is right now, and hand back a ranked list with the reason next to every name.

  1. 01Describe them

    One plain sentence. Role, city, stack, stage, whatever matters to you.

  2. 02I read the web live

    GitHub, public LinkedIn and Crunchbase records, the open web. Not a database that went stale last quarter.

  3. 03You read the shortlist

    Ranked, with the reasoning under every name. Open a profile, ask a follow-up, narrow it down.

  • No boolean, no filters, no seat to buy. One box.
  • Read at search time, so a profile updated yesterday counts today.
  • Every step visible as it runs, every name with its reason.
