About

Most engineering problems are not just technical. They are behavioural. Why do developers freeze under pressure? Why do simple bugs take hours to debug? Why do experienced engineers struggle to communicate clearly? These are not coding problems. They are thinking problems. I’m a Senior iOS Expert at Tesco with 15+ years of experience building, debugging, and scaling real-world applications. Written 1.5million lines of code and counting. Over time, I’ve realised that strong engineering is not just about writing better code. It is about understanding how we think, decide, and perform under constraints. This is where I focus. I explore: - iOS engineering through real production challenges - Behavioural patterns behind debugging and decision-making - How developers think under pressure and uncertainty I occasionally share insights from evaluating engineers, but more importantly, I focus on what actually makes someone effective in real world systems. If you’re interested in: Becoming a better iOS Engineer who think more clearly while solving problems, understanding the psychology behind the performance, You will find the value right here.

Software Development Engineer 3: WL2

Oct 2022 – Present · 3 yrs 7 mos · Bengaluru · Hybrid

Designed and built scalable iOS applications used in real-world production environments, focusing on performance, reliability, and maintainability
Improved application performance by identifying non-obvious bottlenecks (hidden blocking calls, inefficient state handling), reducing latency and enhancing user experience
Debugged complex, cross module issues by applying structured problem solving approaches rather than trial and error fixes
Contributed to architectural decisions, ensuring systems are modular, testable, and adaptable to evolving product requirements
Focused on how engineers interact with systems; identifying patterns in how design decisions, assumptions, and cognitive biases impact code quality and debugging efficiency
Applied behavioural thinking to engineering problems, improving decision making under constraints such as time pressure, incomplete information, and production urgency
Collaborated across teams to simplify complex technical concepts, improving clarity in communication and reducing misalignment during development cycles
Evaluated engineers (interviewing/mentoring) with emphasis on thinking patterns, communication clarity, and problem decomposition rather than just coding output
Behavioural Engineering Focus:
Studied and applied behavioral patterns in software development, particularly in debugging, performance optimisation, and decision-making
Identified how cognitive load, pressure, and assumptions affect engineering outcomes
Developed frameworks to approach problems with clarity, structure, and reduced bias
