End-to-End Engineering Solutions For Your Business
by Jaroslaw ( Jarek ) Lupinski
About Me
Good artists copy; great artists steal.
I take napkin sketches and bring them to market. Starting with a thorough requirements
analysis and rapidly prototyping a Minimum Viable Product, I use the latest Cloud tools
to engineer a scaleable solution that stays lean, reliable, and flexible.
Born in Brooklyn, I graduated with a Bachelors of Engineering from Stevens Institute of
Technology. I have worked at SAP, Snapchat, Citizen, and Mt. Sinai, writing software and
building mission-critical systems, wearing many hats, and leading junior engineers by
example.
Christian Marclay x Snap: Sound Stories
At Snapchat I had the opportunity to work with Christian Marclay, where we
explored how to express and play with the sonic signature of Snaps. For the
Sound Stories exhibition presented at Cannes Lions, I created the "Snap
Piano" that played Snaps to the tune of the attached piano.
At SAP I worked on projects focused on quickly generating value for new
customers. I worked in their Mobile and then Cloud Teams, helping our
customers uncover inefficiencies in their implementations and designing
custom solutions for difficult integrations.
My Software Defined Radio solution powers Citizen's R1 Public Radio
ingestion flow. Tagging the audio clips using Machine Learning enabled our
Analysts to create incident reports for more cities simultaneously.
Every journey of a thousand miles begins with a single step. Knowing when to
keep moving forward and when to pivot is the discipline behind Rapid
Prototyping; after each trial you naturally want to move faster to push your
concept, but it is important to stay flexible enough to test out a more
lucrative space if it presents itself after beta.
I will turn your Minimum Viable Product into a series of achievable milestones,
with analytics and tracing built into each feature and potential revenue
generator. With each success and failure carefully analyzed using established
standards, each Rapid Prototype can be quickly tested to help discover the best
path towards ROI.
They say great science is built on the shoulders of giants. Not here...
we do all our science from scratch. No hand holding.
Once a Rapid Prototype trial reaches Alpha status, it is time to begin setting
up the field for further success. Dev Ops and Tooling refers to all the help
that a single engineer can use to complete the work of 50 engineers; what used
to take an entire team months to implement can now be woven together in a week
using the latest Tooling.
As soon as your alpha audience begins to enjoy your product, Dev Ops and Tooling
also makes sure that their experience stays consistent while your features and
capabilities grow. Automated integration and load testing ensure that the
business can reliably respond to requests made even during the most demanding
holiday schedules without waking up on-call staff.
When I have fully decided that a result is worth getting, I go about it,
and make trial after trial, until it comes.
Serving every customer aorund the world 24/7/365 99.9999% of the time requires a
Multi-Cloud solution. My experience with AWS, GCloud, Heroku, and Azure lets me
write applications that can be deployed to multiple environments using a single
codebase and a well-designed CI/CD pipeline.
The reasons for remaining On-Premise are equally valid; certain applications
must remain air-gapped for compliance or other concerns. Whether the network is
a VPC or a fully isolated Ring Network, my approach is to start with your
immediate isolation concerns and tool your business priorities to match.
You get used to it, though. Your brain does the translating. I don't
even see the code. All I see is blonde, brunette, and redhead.
Your customers visit using iPhones, Androids, Windows PCs, Windows Phones,
Samsung phones, Macs, Linux Desktops, and they all expect the best experience
for their platform. I deliver solutions that understand the nuances of each platform
so that your customers enjoy their interaction no matter which door they use to enter.
When it comes down to shaving nanoseconds off your solution to keep up with the
competition or the laws of physics, my experience programming bare-metal applications allows
me to squeeze every cycle out of the most powerful CPUs on the market today.
The world is not enough... Family motto.
Now that your business has breached the billion-user mark, your service must be
expected to serve not only every person on the planet, but every other non-human
client that may attempt to use your service at any given time, such as IoT
devices, timed jobs, and approved bots. Technology has been able to keep up with
solutions such as Function-as-a-Service and Kubernetes, which have brought down
the barrier to entry for anyone wanting to quickly prove out a concept or
alpha-test a project without worrying about suddenly running out of resources.
Filtering out malicious traffic on top of that seems like a difficult task, but
my experience with the latest trends in development frameworks and big-box
solutions allows me to engineer resilient multi-tenant cloud stacks hosted on
Google, Amazon, and Microsoft offerings simultaneously. Security and resilience
always come first, and with careful planning the security solution can be
completely transparent to the actual application flow.
"jarek319 retrofitted a Sun type S keyboard so that it can be used as a generic USB HID
device. Teensy-LC acts as a bridge between the Sun Type S serial protocol and USB. The
Teensy-LC converts the proprietary serial protocol into common keycodes readable by
generic USB keyboard drivers on all modern operating systems."
"The Zamek is an open source hardware project, aiming to create a secure, digital,
password manager that you can throw in your pocket along with your keys. The project is
still in development, and I wanted to say thank you to Jarek for sending me this early
beta version. Let's have a look at it."
"Are you hoping to one day start your own Starscream, Anamanaguchi or other totally
radical chiptunes band... you can donate $50 to grab a "Chip Maestro" -- an NES
cartridge that turns your old-school gaming console into a decidedly new-school MIDI
synthesizer."
