About

Engineered,
then coded.

I crossed from precision manufacturing into software engineering — bringing a discipline where edge cases are assumed, not discovered. Today I build privacy-first tools, encryption software, and cross-platform apps that work without a cloud.

Timeline

The Road Here

4 milestones
2019

The Spark

Self-Taught

Started self-learning programming — Python, web basics, first lines of code. The beginning of understanding what software can actually do, and why the details matter.

PythonWeb BasicsSelf-Learning
2019 – 2022

Diploma in DTDM

Student

Graduated with a Diploma in Tool & Die Making. Engineering precision at micron tolerances built a mindset that transferred directly into software: design for edge cases first, test every assumption, measure before you cut.

Industry Experience

Tool & Die Designer

Worked in precision manufacturing where errors are physically costly. This discipline carries into every codebase: validate inputs, handle failures gracefully, never ship what you haven't stress-tested under real conditions.

2024 – Present

Computer Science Degree

Student & Freelancer

Pursuing CS while actively shipping real products for clients. Deepening foundations in algorithms, system design, and AI/ML — applied to actual problems, not just coursework exercises.

Direction

What I Focus On

4 areas
01

Privacy & Security Tools

Software where privacy is an architecture constraint, not a feature. AES-256, zero-knowledge design, steganography — built into products people actually use.

Offline-First Software

Cloud dependency is a choice. Local-first architecture with optional sync — full user control, no account required to use the app.

Computer Vision

Cameras as accessibility input devices. MediaPipe landmark detection mapped to screen coordinates at sub-50ms latency — no specialist hardware.

04

Cross-Platform Apps

One problem, the right platform. Web, Windows, Android, iOS — choosing the best tool per target rather than forcing a single stack everywhere.
