Yippify is a small software engineering company that works with growing businesses, startups, and government teams. We build custom web applications and internal tools that replace spreadsheets and manual workflows, develop SaaS products and MVPs, and modernize existing applications and their cloud infrastructure while they stay in production.
You don’t need a specification to talk to us. Bring the spreadsheet, the slow process, or the product idea, and we’ll tell you whether it needs new software, changes to what you already have, or something simpler.
20+ years building and running production software. Architecture through deployment, handled by the same people. A small team, so you talk directly to the engineers doing the work.

Most projects start with a sentence like one of these. Sometimes the fix is a new application. Sometimes it’s an integration, a change to the system you already have, or no new software at all.
We learn how the work happens today, build the smallest version that helps, get it into real use, and improve it based on what people actually do with it.
Each step is small, so you see working software early and can change direction cheaply.
Our engineering leadership has built or led work on SaaS platforms, search systems, publishing platforms, mobile apps and APIs, and AWS infrastructure.
Most of that experience goes into deciding what to leave out. We’ll add queues, separate services, or a larger cloud setup when the problem needs them, and we’ll say so when one well-built application is enough.
React and Next.js frontends on Python, Django, Rails, or Node.js backends, built for what the product needs now and easy to extend later.
APIs that give each piece of data one owner, with retries and monitoring so a failed sync gets noticed.
AWS infrastructure in code, CI/CD, and monitoring, so releases are routine and problems surface before customers report them.
Our own products are the clearest evidence we can show of how we work. Each one started with a specific problem and has a live site, and each project page explains the product decisions, the architecture, and how it’s deployed.

A B2B SaaS product we built to connect delivery signals, from scope change to release lag, so teams can see what happened, why, and what needs attention.
Our playground: a catalog of small browser tools, from a Jira sprint analyzer to a SQL JOIN visualizer, each built to do one job.

Illustrative workout built from structured steps
Free tools that turn cycling training data into plain explanations: power zones in watts, workout load, structured workouts, and FIT files for a bike computer.
A GovCon platform that helps small businesses find SAM.gov opportunities worth pursuing, check fit, make Go/No-Go decisions, and turn solicitations into a compliance matrix, in one workflow.
New SAM.gov notices matched to a company profile. Sample data.
For a local business or a community event, the website has one job: help the visitor call, visit, register, volunteer, or sponsor. We built these two around that next step.
Most projects combine two or more of these. See the kinds of software we build
Take a product idea to a first version people can use, then through production and the features real users ask for.
For the spreadsheet that became an operations system, the report someone rebuilds every week, and the data your team copies between apps.
Make an existing application safer to change: upgrades, tests, deployment, and architecture work, done while it stays in production.
A second opinion before an expensive decision: rewrite or modernize, build or buy, one application or several services.
AI tools have made code faster to write. They haven’t made it easier to decide what to build, what to leave out, or whether your team can still run the result in two years. That judgment is most of what an experienced engineer is for.
VeloWise, SurgeIQ, and FedPath are products we build and run. Useful Little Tools is where we try small ideas quickly. The Union City Smog Check and Berkeley Omnium websites were built for the people who run them. Each started from a specific question: what does a delivery lead need to see, what does a cyclist’s power data mean, is this federal contract worth bidding on?
That’s how most conversations start. Describe what’s slow, manual, or fragile. We’ll reply with a few questions and a straight answer on whether software is the right fix.
