(through Twin Prime acquisition)- Building and scaling mobile technology targeted to deliver an optimal network speed and UI/UX experience- Coordination of software integration efforts between cross-functional teams (iOS, Android, Security, Audit, Compliance, Infrastructure)- Establishing best practices and processes around mobile product software engineering- Participation in design of next-generation mobile architecture for network speed optimization- Design and implementation of features in a full-stack product (iOS/C/Python/Ruby)

We were acquired by Salesforce. Responsibilities:- Design and implementation of features for Twin Prime GLAS technology (Android/iOS)- Wrote server-side code for Twin Prime GLAS Accelerators (ANSI C/JSON/AWS]- Extended build/release infrastructure (GNU makefiles, Jenkins, Git)- Wrote iOS client-side code and unit tests for Twin Prime SDK (Objective C/Python)- A lot of HTTP debugging

- Acted as a primary reviewer of changes to a 100k+ source code base for a team of 15+ engineers.- Mentored and trained new hires.- Created new hire guide adopted across 2 different organizations.- Designed and implemented frameworks for Single Event Upset (SEU) characterization of Xilinx Zynq 7000.- Performed experiments in UC Davis Crocker Nuclear Lab.- Wrote and presented publications on SEU characterization of Xilinx products.- Wrote drivers for SLTOS for MPSoC architecture.- Wrote DisplayPort pattern generator and checker in Verilog, simulated and synthesized in the AXI MPSoC project- Worked on industry's 1st 16nm chip (Ultrascale MPSoC)- Evaluated Cortex-R architecture.- Ported SLTOS from ARMv7 to Cortex R5 and wrote necessary drivers.- Ported SLTOS from generic ARMv8 to ARM Foundation simulator and Xilinx MPSoC prototyping platform.- Performed competitive analysis of Xilinx SoC products

- Custom Chip Validation OS design and implementation for ARMv7/v7T (assembly, ANSI C).- Designed and implemented modules, drivers and improvements to On-Chip Memory, DDR, ADC, AFI, PCAP and others.- Ported the OS to several new architectures.- Designed and implemented frameworks for automated testing under extreme conditions (PVT, SEU) and data visualization (Perl, HTML5, jQuery)

FreeBSD src commiter. Worked mainly on small fixes to both user and kernel-space code. Major interests: OS kernel implementation, low-level programming, computer architecture.

Participated in DARPA sponsored project CTSRD, managed by SRI/Computer Laboratory of Cambridge University.- Worked independently on PISM (Pluggable Infrastructure for Simulational Models)- Implemented Ethernet MAC simulation model for CHERI (64-bit MIPS with security extensions).

- Focused on system level and bare metal ARM assembler/ANSI C programming- Implemented randomizing drivers and integrated them into the System Level Testing OS (SLTOS).- Worked directly with IC Design Team and helped with narrowing down RTL issues.- Worked on experimental tasks such as porting OS to the user-space.

- Wrote FreeBSD driver for NetFPGA card.- Presented work at Ericsson Nomadic Lab, HIIT and Cambridge Computer Laboratory during FreeBSD Developers Meeting (Cambridge)

- Hired number of times as a system and network administrator.- Worked on areas related to LAMP platform configurations, SMTP, POP3, IMAP as well as system security and performance.- Took care of several UNIX-based servers acting as configurable routers, especially for privately held local area networks.- Utilized the FreeBSD operating system as well as Slackware GNU/Linux.

One month internship in Thomas Sterling research group on innovative HPC architecture (ParalleX project)- Proposed OS system architecture; prepared simple driver for Spartan PCIe FPGA card: http://freebsd.czest.pl/~wkoszek/lsu/xc3s1000_pcie.tgz (later, driver has been reused multiple times by people posting on Xilinx forums)

System-level (UNIX/Linux) security software analysis.
