• Working on a live portfolio risk evaluation system.
• Sped up a batch from 6 hours to 1 minute per scenario.

Worked on a foreign exchange (FX) options pricing service:

• Sped up pricing 2-10 times.
• Redesigned and simplified the code.
• Fixed hard-to-find pricing bugs (reduced support time by 10x).
• Infrastructure, performance tuning, code quality, mentoring.

Developed an advanced web-based RSS feed reader (bazqux.com).

I was involved in everything: marketing, customer support, design, frontend, backend, and server administration.

Frontend: Ur/Web + JavaScript, CSS (Stylus), Webpack.
Backend: Haskell + Ur/Web, Riak, ElasticSearch, bare metal Debian servers.

Technical highlights:

• Commercial Haskell app running in production since 2012.
• Complex and highly customizable yet simple-looking single-page app.
• High-performance distributed feed fetching.
• Complex and performant filters.
• Wonderful mobile web interface (users prefer it to native mobile apps).
• Magically converts any article to responsive HTML.

Packages on Hackage:

• fast-tagsoup — fast XML tag soup parser.
• css-syntax — significant performance improvement in PR #3.
• http-conduit-downloader — web-crawler downloader.
• HsOpenSSL, text-icu — maintainer.

Developed various parts of microelectronics IDE: VHDL and CPU core simulator, C debugger, waveform viewer (displays gigabytes of data in real-time), UI. Mostly Haskell with bits of C/C#/Java.

Videoslot games (2D & 3D ones), developed using OCaml, C++, Python, Haskell, OpenGL, GLSL, OpenAL, 3dsmax, flash, Linux.

Hired and worked with remote developers on web and client-server applications (Erlang & Haskell).

Security audio recording system and a lovely records browser.

Tons of audio analysis, UI, plus various stuff such as AVR firmware, USB driver, video recording, import from other similar systems, and installation packages.

Used C++Builder, VC++, IAR C, STL, boost, gcc, emacs.
