ABOUT ME

Systems & Backend Architect | Expert Rust, Go & Python Mentor

I am a Lead Systems & Backend Architect with 12 years of industry experience and over 4 years of formal experience as a Corporate Technical Trainer. I help developers, startup founders, and students unblock complex technical challenges, debug production issues under pressure, and master advanced architectural concepts.

My background is uniquely built for live, hands-on mentorship and technical advisory. I specialize in the "T-Shaped" intersection of systems programming and scalable backend architecture, and I can help you with:

• Advanced Python (FastAPI, Django, asynchronous tasks, unit testing)
• Go (Golang) & Distributed Systems (Microservices, concurrency models)
• Systems Programming & Rust (Memory safety, toolchain, eBPF)
• Cloud-Native & DevOps (Kubernetes, Rancher, Docker, AWS SRE)
• Database Optimization (PostgreSQL query profiling, N+1 loop fixing, indexing)

Whether you need a live pair-programming session to debug a persistent error, an in-depth code review to optimize your database query paths, or high-level architecture planning for your startup, I can guide you step-by-step.

Let's hop on a 1:1 session to get your code robust, clean, and fully optimized!

Handling Multiple Instances of Django Forms in Templates

When you’re using Django Forms in a template, you’ll most likely run into situations where you need to handle more than one instance. Moreover, you’d need to know how to track the number of instances the user has added. This post is written to address this issue.

The Challenge: Diagnosing tail-latency and microservice bottlenecks in production often requires knowing exactly why a thread is not executing. Standard tools (like top or pidstat) show high-level CPU usage but fail to break down the exact microsecond durations threads spend waiting. To truly debug a bottleneck, engineers need to see the exact time spent in states like "Runnable" (CPU starvation), "Sleeping" (Network/Locks), or "Uninterruptible" (Disk I/O Wait). The Architecture & Solution: Inspired by the methodologies in Brendan Gregg’s Systems Performance, I am engineering tsastat, a high-performance Linux profiling tool written entirely in Rust. Granular Thread State Tracking: The tool parses deep OS-level thread scheduling data to provide a real-time, rolling output of Thread State Analysis (TSA), calculating the exact time spent in each execution state. Zero-Cost Observation: To prevent the "observer effect" (where the monitoring tool itself causes CPU load), I am utilizing Rust's zero-cost abstractions to track nanosecond-level state transitions with virtually zero memory overhead or GC pauses.

Built a programmable firewall running directly inside the Linux Kernel using Rust and eBPF (XDP) to protect AI inference servers from volumetric DDoS attacks. Achieved line-rate packet filtering and stateful rate-limiting by executing logic natively in the network driver, preventing sk_buff allocation memory exhaustion.
