HELLO, I'M JASON.
A Computer Engineer at Brown University
Hello! My name is Jason Pien and I am a junior at Brown University set to graduate with a B.S. in Computer Engineering in May 2025. I do hardware, software, and more! Looking for a full-time job in chip design.
This summer I am trying my hand at Software Engineering, working at EY within their financial services engineering team.
I grew up around Summit New Jersey. I am into a lot of things: programming, hardware, poker, DJing, and snowboarding.
Digital Circuit Design
I am proficient in Verilog HDL for RTL code. I also learned about synthesis, floor plan, and placement routing. Having survived my FPGA/Verilog classes, I will be returning as a TA under Professor Sherief Reda.
My interest and motivation come from making computation faster as well-designed circuits can easily achieve 10x or even 100x performance compared to the best software-implemented algorithms.
Programming!
My language of choice is Python 3.9.18. I can write in any other programming language with reference to documentation
My motivation for learning software is to explore the interaction between software and hardware. By understanding the complexities of both, I am in a better position to build more efficient systems. I am particularly interested in exploring efficient and fast computation within the realms of AI chips and GPUs.
Verilog RISC-V Pipelined Processor From Scratch
I designed and synthesized a functional and FPGA-deployable RISC-V 2-stage pipelined processor architecture using Verilog HDL on the Quartus Intel Prime EDA suite. The initial specification was to develop a single-cycle processor operating at a nominal frequency of 50MHz, capable of executing a program that computed the factorial of 6 (n-factorial, where n=6) with a Cycles Per Instruction (CPI) of 1, resulting in a runtime of 1440 nanoseconds (20 ns x 72 cycles).
In my first attempt, I could push my frequency to 100MHz, far exceeding the requirements. Following new spec requirements for a pipelined design, my benchmark was to hit a 15-20% improvement in runtime. I analyzed the spec requirements and my design and found that I could get away with a 2-stage pipeline, reducing the number of required cycles at the tradeoff of a lower clock frequency since 100MHz was already high. Post-implementation of the 2-stage pipeline and logic optimization, as well as synthesis and place-and-route, I achieved a significant performance enhancement. The optimized processor attained a maximum operating frequency of 145MHz, a 190% increase in clock speed compared to the initial design specification. This optimization translated to a runtime of 572 nanoseconds (6.896 ns x 83 cycles), a 60.3% improvement over the original design.
I had a slight increase in used cycles since I made the design choice to use hardware stalls on jal or jalr instructions on a 2-stage pipeline while still hitting the required specs. Through critical path analysis, I identified potential for further performance improvement by pipelining the processor into 3 stages and pipelining the multiplier unit within the Arithmetic Logic Unit (ALU), as the multiply operation exhibited the longest propagation delay.
Attained a 1.26x speed-up over the single-cycle design baseline.
Achieved a 2.52x speed-up compared to the target performance specification.
Ranked 2nd for runtime performance, (7% slower than the 1st place design).

To be inducted, juniors must rank in the top eighth of their class and seniors in the top fifth.
FinTech Club
Executive Board | Head of Tech
FinTech@Brown has been on campus for over 10 years now. We have worked to connect students with the FinTech industry and interact with opportunities for students in FinTech. Our goal is to help educate students about the industry and how to get involved with financial technology as a whole.
As the Head of Tech, my responsibilities revolve around educating our members in the technology used in finance as well as maintaining our website.
Brown Taekwondo Club
Team A1 Black Belt Sparring Member
In freshman year, I competed for Brown Taekwondo at the A1 sparring level. Within the club, you get placed into A1-A3, B1-B3, C1-C3. I competed both regionally and at NCTA Collegiate Nationals where I placed 3rd.
Practices run 4 times a week, each of which are 3 hours long. Fun fact, I had to cut 20 pounds in 1 week for nationals!

June — Sept 2023
Co-Founder
Freedays
B-lab Summer Accelerator
After being accepted into Brown University's premier summer start-up accelerator, I had the fortune to experience the many ups and downs of running a lean start-up.
The idea of Freedays was to help college students quit vaping.
On the technical side of things, I initially built a hardware breadboard prototype that would, throughout the day, disable the vape. It was essentially an ESP32 DevKit C wired to a disposable vape that interrupted the voltage supply to the atomizer based on the time of day. Following technical breakthroughs and legal regulations, we pivoted to software were I developed the MVP to our "mobile AI therapist" which utilized an API call to chat-gpt-3.5-turbo.
My biggest takeaway was the opportunity to learn new skills and produce on the fly. I learned everything from start-up legal, customer validation, bottom-up research, business finance, and how to adapt.
What I found most exciting was making my build-measure-learn feedback loop as fast as possible. I learned that the best way to build a new product is to understand your assumptions, and vigorously test them as fast as possible.
March — Dec 2023
UI/UX Designer
Linkr
I joined Linkr part-time, leading the renovation of our website platform. Linkr served as an all-in-one monetization platform for micro-influencers serving 15M+ users. I primarily used Figma and Balsamiq to develop wireframes for a more concise, readable, and cleaner UX.
I learned a lot about managing a team, producing fast-paced deliverables, handling multiple projects, and website UX design.
What surprised me the most was having to bridge the culture gap between Chinese and American user habits. Our platform was designed by a team in China, and as we looked to expand into the American market, I quickly learned that Chinese UI expectations are vastly different. I had to convert a cluttered, "everything in your face" UI to a simpler and cleaner experience, catering to our new American users.
Aug — Jan 2023
Intro to Engineering Teaching Assistant
Brown School of Engineering
I taught engineering lab to 10 freshman students training them in MATLab, prototyping machinery, and went over the math/physics taught in class.
I developed valuable skills such as deconstructing complex problems into more manageable components, making them easier to understand through clear and concise explanations. This would help me later down the line as a founder, engineer, and manager
Jun — Present
Groov
Intern then later hired as a Consultant
UPenn Wharton Venture Lab | Now Stealth Startup
Groov is a startup that was born within Wharton Venture Labs. Groov brings the luxury of custom insoles to the athleisure market. As an intern, I developed the video instructions for the scanning process which was used in our Beta app.
I learned about the fast paced culture of a startup and how to quickly adapt and manage a project with fast turnarounds. I also learned how to properly conduct A/B testing.
Fast forward 2 years later, CEO Dan Cataldi brought me back onto the team as a consultant, using my insights as the creator of the original scanning instructions to better fit the company's current needs. As of late, I have been sitting in on meetings with our animators who are creating the instructional videos while also continuing my past work and improving our onboarding process.
Dan Cataldi | Groov Founder & CEO
"Working with Jason, it was clear that he brought a unique combination of technical nuance, curiosity, and initiative. Having demonstrated his ability to create positive leverage from day one, Jason became a fundamental part of the team, owning a work stream while simultaneously stepping in to fill our growing startup’s needs wherever they arose. In a world in which the bridges we can draw between the technical and the human increasingly become our greatest assets, Jason contributes in a way that would make any employer lucky to have him."
Jude Adelman | Head TA
"Jason's passion for engineering, combined with his great teaching abilities, made him a standout mentor. He consistently demonstrated a high level of professionalism and work ethic, earning my trust quickly as well as the respect of other mentors and his mentees. I wholeheartedly recommend Jason for any engineering position, confident that he will be a valuable asset to any organization fortunate enough to have him on their team."
