Client site · jess-fillyo.vercel.app
A booking site for a New York model. Work grid, runway reel, measurements and downloadable digitals in one place, so an agency can see everything without asking for it.
Open the live siteSites, tools and games · New York & New Jersey
Six sites, six live maps, seven tools, three games, a colony of 3D ants and a set of badge marks. Client work, concepts for companies I wanted to build for, a sofa you can stand in your own room, a map of every restaurant in New York, and a falling sand simulator. Most of it opens in one click, right from this page.
All of it written by hand, in code. No page builders, no templates.
What I doWorking range
Nine things I have shipped, not nine things I have read about. Every one of them points at something on this page you can open and poke at.
Storefronts, booking pages, service sites. Written by hand so they load fast on a phone and nobody pays a monthly fee to keep them alive. See Grim Reaper Gardens, Jess Fillyo and Margie Horowitz.
A real model in the page instead of a photo shoot: change the fabric with no reload, then stand the thing in your own room from a phone browser, with no app to install. See Holloway and Barham.
Public data pulled on load and turned into something readable, with the colours and the axes chosen on purpose. Sometimes that data is moving: Trains Now decodes the MTA's realtime feed and Docks Now reloads every fifteen seconds.
A page that listens, answers out loud, and knows when to stop talking and take the booking. See Night Desk.
Physics on nearly a million cells at sixty frames a second in a browser tab, with heat, fire and chemistry running between the materials. See Granulab.
Room codes, a server that holds the truth, and two people in different houses watching the same board move. See Ant Raid.
Installed to a phone home screen, opening offline, keeping your progress on the device instead of on somebody else's server. See FALA.
Logos built as a system rather than as a drawing, and documents set to survive a printer at 300 dots per inch. See Marks and print, further down.
The spreadsheet nobody wants to touch, the report someone retypes every Monday, the job that should have been running itself for a year. Python, on a schedule, with the output checked.
Plain HTML, CSS and JavaScript wherever that is enough, which is most of the time. Three.js and WebGL when the thing has to be three dimensional, Canvas 2D and WebAudio for the games, glTF and USDZ for models, Python for the data work, and hosting on Vercel or GitHub Pages so there is nothing to maintain.
Selected workSpecimen record 01-06
Six real businesses. Three are live client sites you can open right now. Three are concepts: I picked the company, worked out what its page should argue, and built it. Every one is built differently, so you are not getting a template with your name dropped into it.

Product visualisation · holloway-barham.vercel.app
A furniture page where the sofa is a real 3D model, not a photograph. Four upholsteries ride inside one glTF file, so changing the fabric swaps the material on the spot with no reload and no second download, and the specification rewrites itself to match. On a phone the same page stands the sofa in your own room. The viewer is also packaged as a WordPress plugin and as a Squarespace injection.

Homepage concept · Los Angeles ghostwriting
For a Los Angeles ghostwriting firm running since 2002. Their real copy, real rates and real reviews, set as an editorial page instead of an agency brochure.
Open the conceptLive dataFetched on load
Not screenshots of data, and not a chart somebody exported last quarter. Every one of these fetches the numbers when you open it, plots them, and hands you the filters. Two of them redraw themselves while you watch, because the feed behind them changes every few seconds. Open one and start dragging.

Live map · bitemap-workflo17.vercel.app
Every restaurant in New York City on one map, 30,075 of them, drawn from the city's own inspection records. Filter by borough, by cuisine, or down to a regional kitchen, search for a dish rather than a name, and the map redraws as you go. There are walking crawls built on top for when you want an afternoon planned rather than a single dinner. It runs on vector tiles, so panning a city's worth of points stays smooth on a phone.

Live dashboard · workflo17.github.io/nyc-pulse
Every 311 complaint filed in the last seven days, fetched from NYC Open Data the moment you load it. Nothing is stored and nothing is stale.

Live subway map · trains-now.vercel.app
Every train the MTA is reporting, right now, on the line it is running. The agency publishes protobuf with no coordinates in it, only "stopped at 42 St" or "in transit to 34 St", so the page decodes the feed by hand, then uses the published schedule to work out which two stations a moving train is between and draws it on the track. It refreshes every 25 seconds and the dots ease across.
Watch it move How a feed with no coordinates becomes a map
Live bike share · docks-now.vercel.app
Every Citi Bike dock in the city, refreshed every fifteen seconds. Ask it for a bike or for a dock and the colours flip to answer the question you actually have.
Open the board
Sales and values · sold-nearby.vercel.app
What actually sold on any block in the five boroughs, with the price, the date, the square footage and what that works out to per foot, straight from the city's own register. Long Island is covered too, all of Nassau and all of Suffolk, which took some digging: the state publishes no individual sale prices out there at all, so the page reads the assessment roll instead and, for the towns that file an assessment rather than a market value, works the value back out using that town's own published ratio of assessment to sale price. Built as the comps half of the seller's question, so it hands off to the net sheet for the other half.
Look up a block How the Long Island prices are derived
Species map · ant-atlas.vercel.app
Every ant anyone has recorded, anywhere on Earth, from museum drawers and phone photographs alike. Pan to a place and it names what lives there.

The conversion tracking behind this site, written rather than installed. A serverless collector, a private store, and a dashboard behind a key. No third-party script and no cookies, so there is no consent banner to click. It is recording your visit right now.
Read the sourceAlso builtGame record 01-03
Not client work, and I am not pretending otherwise. They are here because the hard parts of a game, physics that has to hold up, netcode, and making a thing feel good under your hand, are the same parts that decide whether a website is worth paying for. Two of the three you can play in a browser right now.

Playable · granulab-workflo17.vercel.app
A falling sand sandbox in the Powder Game line. More than 40 materials with heat, fire and real chemistry between them, plus a maker for inventing your own element and its reactions. Nearly a million cells, 60 frames a second, no plugin.

Playable · workflo17.github.io/ant-td
A tower defense where the towers are ants and the trail runs across a picnic blanket. Six maps, one for each hour of the day. Every sprite is drawn in code and every sound is synthesised, so the whole game is a few hundred kilobytes and works offline.

Multiplayer · github.com/workflo17/ant-raid
The other half of Grubs TD: you are the wave. Two colonies, three roads, sugar to spend on the ants you send and the ones you keep home. You get a room code and send it to a friend. It needs a socket held open, so it cannot live on static hosting the way the rest of this page does. The whole thing, game server included, is on GitHub.
Read the source3DModelled, rigged, rendered
From Vivarium, an ant colony simulator I have been building. The ants are real geometry on a real skeleton, not sprites. Pick a caste below and drag it around, then watch the same three turn.
The minor worker, the one that does most of the work in a real colony. 44,859 triangles, three texture maps and a clearcoat pass for the wet look of chitin. All three castes ride the same 59 bone skeleton, which is what lets one animation drive the whole colony.
Worker · walking to camera
The hard part of insect walking is that the foot has to stay where it landed while the body moves over it. Get that wrong and the ant skates.
Turntable · silhouette check
Every model gets spun through a full circle before it is allowed near the game. It is the fastest way to catch a proportion that only reads from one angle.
PipelinePhotograph in, AR asset out
Software I wrote that turns one product photograph into a 3D asset a shopper can stand in their own room at true size. No scanning rig, no modelling contract, no per-model licence, and nothing leaves the building: every stage runs on one desktop. Below is a chair it made. Switch between what the reconstruction handed back and what the pipeline made of it.
Straight out of the reconstruction model. 500,580 triangles before I thin it, no texture at all, no real-world size, and the studio floor came back as a slab of geometry because the model cannot tell the product from the set it was shot on.

Workflow · image, geometry, product asset
The middle panel is the honest one. A reconstruction model returns shape and nothing else: no colour, no scale, not even normals, and it happily rebuilds the seamless and the contact shadow as a plate of geometry under the chair. Everything between that panel and the third one is code I had to write.

The software · Node and Python
Finding the floor is the part I am proudest of. You cannot find it by looking for dense geometry, because a flat plate simplifies down to almost no vertices. You can find it by width: a reconstructed floor spans about twice the band directly above it, because what stands on it are chair legs. One measurement, one cut.

AR · glTF for Android, USDZ for iOS
The asset ships as glTF for the web and Android and as a matching USDZ for iOS AR Quick Look, both at metric scale with pinch-to-resize switched off, because the question a shopper is actually asking is whether it fits. The write-up, including what the technique cannot do, is on the demo site.

Not everything ends up in a browser.

Identity study · drawn in code
Outdoor badge marks for three imagined brands, emitted as SVG from one shared Python shell so the set is provably a system instead of three lookalikes. Every stroke is 3, 6 or 9 units and never anything else, and each mark was proofed at 256, 512 and 1200 pixels, because a badge that only works large is a badge that fails on a phone.
Build notesLonger form
Three of these had a problem in the middle that took longer than the rest of the build put together. These are those parts: what the obstacle was, what I tried, and what the thing still cannot do.
Sold Nearby · open data
New York State publishes no individual sale prices for Nassau or Suffolk at all. The way out was a table almost nobody reads: the state's own published ratio of assessment to sale price, per town, per year.

The MTA reports "stopped at 42 St", never a latitude. Sixty lines of hand-written protobuf, then the published schedule to work out which two stations a moving train is between.
Read the notePipeline · 3D
A reconstruction model hands back shape and nothing else, and rebuilds the studio floor as a slab of geometry under the product. Finding that floor by width rather than by density is the part I am proudest of.

I read everything that arrives. Tell me what you are trying to make and I will tell you honestly whether I am the right person to make it.
I am Don Florencio, and Workflo is the name I build under. Websites, small tools and games out of New York and New Jersey, mostly alone and mostly in plain HTML, CSS and JavaScript. Everything on this page I made, and the source for a good deal of it is on GitHub. Thanks for looking.
