Hi, I'm a Senior Software Engineer working for DSI Data Science Institute. I'm currently allocated to the Internet Equity Initiative (IEI) as a Backend/Data Engineer. I have 20+ years of working on Computer Networks with experience in Security, HPC, and Mobile. Recently, I've been shifting the gears for everything's Data and Education, BI, and Decision-making processes. My latest project is running at https://beadchallenge.org with a serverless backend.
Instead of a wordy Resume, here's a more relaxed collage of images with important documentation of my work as most of it is open source (opinions are my own). Also, check out my latest WIP on UI dashboarding IEI Netrics data here.
Figure 1. This is the Netrics backend stack I was responsible for on the left. In prod for 3 years and crossed the 1 billion data-point mark of encrypted data. The stack includes small Golang data collection applications, python IaC (Serverless AWS code), terraform code, SQL database schema, parallel Python data ingestion, Kafka producer/consumers. On the right, is the System Design for https://beadchallenge.org.
Figure 2. Aggregated average latency (active unloaded ICMP) for all Netrics deployed devices in Chicago city. As expected: fiber tech has lower latency compared to the other technologies. Data warehoused on TimescaleDB, image extracted from Superset BI tool. Estimated devices deployed: 120 in Chicago area. We benchmark the internet for ISPs to ensure internet consumers are getting a fair performance from their contracted services.
Figure 3. A Netrics Grafana dashboard with fluctuation on both latency and speed test. High-performance multiplayer games must have Netrics installed and keep an eye on their performance over time.
Figure 4. Campus deployment of Netrics, showing high latency for an outlier (Booth School). Image extracted from Looker Studio.
Figure 5. BEADChallenge.org analytics, where the internet speeds are lower (unserved/underserved) in IL, USA? / Satellite Internet Performance: The key technology responsible for bringing Internet to unserved. (Download / Upload in Mbps).
Figure 6. Data analysis work for the Internet Equity Initiative group. Does the low-income population have worse internet performance than the high-income? What does it mean to be an underserved or unserved area regarding broadband infrastructure? Is the broadband evolving in the US (2019 - 2021 comparison)?

Figure 7. Netrics Passive Schematics developed circa 2015. A $200 kit (Jetson Nano 472 GFLOPS) for high-performance passive packet capture, network monitoring and ML inference.
Figure 8. My earlier work (circa 2009-2011) on Deep Packet Inspection (DPI) for Alcatel-Lucent, programming CloudShield/IBM equipment (PacketC / C ). I was the principal engineer for the protocol/app service detection intelligence of the network traffic control engine called Agya. The solution was deployed in the Latin America region, mainly in Brazil.
