The story behind the code
About Me
My journey into software engineering didn't start with a compiler — it started with people. Working as a Service Analyst, I learned to listen: to users, to processes, to the gaps between what systems promise and what people actually need.
That foundation shaped everything that followed. As a Quality Analyst, I developed a rigorous mindset — understanding that great software isn't just functional, it's trustworthy. I learned to break things intentionally so that, when they mattered most, they wouldn't break at all.
Today, as a Software Engineer, I bring that rare combination to every project: deep user empathy, a quality-first instinct, and the technical skills to build full-stack solutions. I work across React, React Native, Python backends, and AWS infrastructure — always with the same question in mind: does this actually work for the person using it?

The path that brought me here
Experience
Software Engineer
TLANtic
Developing and maintaining cross-platform applications using React, React Native, and Python. Designing event-driven microservices on AWS (Kinesis, DynamoDB, S3). Collaborating closely with product and design teams to deliver user-centred features with a focus on reliability and performance.
Quality Analyst
TLANtic
Owned end-to-end quality assurance across functional, integration, and performance testing. Built and maintained structured test plans and reported critical bugs that prevented production incidents. Introduced testing strategies that improved release confidence and team velocity.
Service Analyst
TLANtic
Bridged the gap between technical teams and business stakeholders. Gathered and documented requirements, analysed service flows, and translated user needs into actionable specifications — building a strong foundation in product thinking and user empathy.
Selected work
Projects
Event-Driven Data Pipeline
A scalable, real-time data ingestion pipeline built on AWS. Processes high-volume streams using Kinesis, stores structured data in DynamoDB, and archives to S3 — designed for reliability and observability.
QA Test Management Platform
An internal web platform for managing test cases, tracking defects, and generating quality reports. Provides teams with real-time insight into test coverage and release readiness.
Mobile App Prototype
A React Native prototype for a client-facing mobile application, built from design specs to interactive prototype. Included custom animations, offline-first data handling, and accessibility compliance.
Data Reporting Automation
A Python-based automation tool that extracts, transforms, and exports business metrics into structured reports. Replaced a manual weekly process and introduced scheduled, consistent data delivery.
