Kalana Hewapathirana / Developer & Educator
I turn complex ideas into useful software. A Computer Science graduate building AI tools, modern web experiences, and better ways to learn — from Sri Lanka.
01 / The approach
My work connects machine learning, software engineering, and the classroom. I care about tools that solve real problems — and make sense to the people using them.
02 / Selected work
Explore applied AI, public-data tools, developer utilities, and interactive learning experiences. Filter by the work that interests you.
A browser-based sandbox that lets learners build, wire, and simulate digital logic circuits in real time — with truth tables, undo history, sharing, and accessibility built into the core experience.
A SMALL IDEA. A LIVE RESULT.
1 AND 1 = 1 · Both inputs are on.
Try it: tap A or B to change the signal.
Turning public CIABOC court cause lists into structured, searchable data with a Python pipeline, API, and interactive dashboard.
A dependency-free Go CLI that loads project-specific environment variables into a single command, with environment isolation and optional Vault integration.
An offline-capable practice interface with review, saved progress, and 23 question banks. Built on community question content credited to its upstream author.
A conversational shopping assistant that understands gift requests, recommends products, remembers preferences, and guides customers through cart, checkout, and payment flows.
A lightweight RAG pipeline that chunks 500 movie plots, stores embeddings in ChromaDB, and uses Gemini to answer grounded questions from a CLI.
A terminal-based job-search co-pilot that scores role fit, monitors public job boards, and generates ATS-optimised PDF résumés tailored to each opportunity.
A calm, offline-capable digital library presenting 17 Sinhala Dhamma books through a five-phase reading path with search, filters, and long-read accessibility controls.
A streamlined interface for transcribing uploaded audio with a fine-tuned Whisper model hosted on Hugging Face.
An end-to-end pipeline that collects SLT Selfcare reviews, identifies and categorises bugs with transformer embeddings, and delivers Streamlit analytics, exports, and email digests.

I work across the stack, connecting intelligent systems with interfaces that remain clear, reliable, and human.
Model development, computer vision, NLP, RAG systems, evaluation, and practical inference workflows.
Responsive web experiences, APIs, dashboards, data flows, and maintainable product architecture.
Student-friendly learning resources and technical tools aligned with Pearson Edexcel computing curricula.
04 / Experience
My path connects applied AI, software delivery, research, and teaching — a mix that keeps the work rigorous and understandable.
Delivering Pearson Edexcel iLowerSecondary and iGCSE ICT / Computer Science through practical, student-centred learning.
Worked on computer vision, NLP, location intelligence, dashboards, and data-driven operational tools.
Built a strong foundation in software engineering, data science, machine learning, and research practice.
05 / Contact
I’m interested in AI/ML, full-stack, educational technology, and collaborative open-source opportunities.
