PRINCIPLES
How I work.
Four rules I keep returning to. They fail more often than they succeed, which is why they are written down.
“The job is not to be the smartest person in the room. The job is to ship a system that survives contact with reality. ”
-
01
Ship over polish
Half a system in production teaches more than a finished one in a notebook. Every project on this site has a real URL.
-
02
Metrics over claims
F1 0.95, 99.8% imbalanced data, 284k transactions. If a number is on this page, it is reproducible from a commit hash.
-
03
Public over private
Open repos, post-mortems on the blog, certifications anyone can verify. Hiding the working out hides the work.
-
04
Boring tools, sharp use
Python, Postgres, Docker, Linux. The accumulated tax of chasing the new framework usually outweighs the lift.
WHAT I CAN HELP YOU WITH
Services.
Four overlapping practices. Real shipped projects across each. See the Recent Projects section for live demos backed by actual code.
02
Cybersecurity Analysis
Threat detection systems, SIEM monitoring, incident response, vulnerability assessments, OWASP Top 10 testing, ISO 27001 / NIST CSF audits.
- SIEM
- OWASP
- NIST CSF
- MITRE ATT&CK
03
Machine Learning
End-to-end pipelines: feature engineering, ensemble models, threshold calibration, deployment to Streamlit / FastAPI services with real metrics.
- scikit-learn
- PyTorch
- XGBoost
- SMOTE
04
Full-Stack & DevOps
Building the dashboards and APIs that surface the data: Flask, FastAPI, React, Astro, Docker, Cloudflare Pages, Hugging Face Spaces.

RIGHT NOW
Currently.
A live snapshot of what is actually on my desk this week. Updated when the work shifts, not on a schedule.
- 01 Building
Hybrid ML IDS, capstone
Isolation Forest plus Random Forest plus Autoencoder ensemble on CICIDS2017. Hitting F1 0.95 on the validation slice. Currently writing the post-mortem on what went wrong on the first three attempts.
#NIDS / HIDS
- 02 Learning
Snowflake performance tuning
Beyond the OCI Data Science cert, working through query profiling, micro-partition pruning, and warehouse sizing on production-shaped datasets. Notes go on the blog when they survive a second pass.
#Data Eng
- 03 Reading
Designing Data-Intensive Applications
Kleppmann, third pass. Each pass surfaces something new now that I have shipped systems instead of just notebooks. The chapter on stream processing is the one that keeps paying interest.

OFF THE CLOCK
Beyond the work.
The hiring page version of me misses everything that actually keeps the work tolerable. Here is the rest of it.
- 01 Gaming
ROG Showdown podiums
Three consecutive 2v2 podium finishes in the ASUS Republic of Gamers Showdown series at The Sports Club: 2nd, 2nd, then 3rd. FPS games sharpen the same kind of pattern recognition I use in security work, only with shorter feedback loops.
- ASUS ROG Showdown
- 2v2
- Podium ×3
- 02 Languages
Three, working order
English (fluent, day-to-day), Hindi (native), Punjabi (conversational). Writing technical material in English is its own skill. Speaking three is occasionally useful in a stand-up; rarely useful in a code review.

Lifting, walking, reading
Strength training four days a week. Long walks around Adelaide for thinking. A non-trivial fraction of any blog post I publish was drafted somewhere between Henley Beach and home.
