I’m a full-stack software engineer with over seven years of experience shipping production systems that businesses depend on. Today I build anti-money laundering (AML), KYC, and fraud detection technology at eSpear LLC. Before that, I worked on Cambio’s COSMIC, an e-healthcare platform used across Scandinavia, and on CodeGen’s TravelBox™, the reservations engine behind major tour operators, airlines, and cruise lines.
My core stack is Java and Spring on the backend with Angular on the front end, and I work comfortably across the full lifecycle: designing APIs, modeling data in SQL and MongoDB, deploying to AWS and OCI, and delivering interfaces people actually enjoy using. Alongside enterprise work, I’ve delivered 25+ five-star freelance projects covering automation, web scraping, and full web applications, and I run DebuggerMe, a live suite of browser-based developer tools built with Next.js.
On the AI side, I design agentic systems: LLM agents that call tools, work with your data through retrieval (RAG), and connect to existing services over MCP. I care as much about the parts that make them trustworthy in production, such as evaluation, guardrails, and observability, as about the prompt. Pairing that with years of enterprise delivery means an agent is built like any other production service: tested, monitored, and maintainable.
I take ownership of what I build, prioritize clean architecture and long-term maintainability, and thrive on teams that share knowledge openly. If you’re looking to build a product, add a feature, or need an engineer who can carry an idea from whiteboard to production, let’s talk.
Responsive interfaces in Angular, React, and Next.js that work as well on a phone as on a desktop, and stay maintainable after launch.
Java and Spring Boot services with secure REST APIs, sensible data models, and the caching and batch processing that keep them fast under load.
Agentic workflows that call tools, query your data with RAG, and connect to your systems over MCP, with the evals and guardrails that keep them reliable once real users are on them.
Scrapers and bots that collect, clean, and deliver data on a schedule, from single-site extraction to bulk processing across thousands of records.
Schema design and query tuning for performance, scale, and data integrity, across relational databases and MongoDB.
Containerised deployments to AWS and Oracle Cloud, with the build and release pipeline set up so shipping is routine rather than an event.
Cross-platform apps in Flutter that ship to both iOS and Android from one codebase, with native-feeling behaviour on each.
Desktop tools for the jobs a browser cannot do, built in Java and JavaFX for teams that need something running on their own machines.
Highlighted are my day-to-day stack
Select a skill to see where I've used it.
Named entity recognition for Colombo Stock Exchange news, trained on a hand-annotated corpus of Sri Lankan financial reporting. Extracts listed companies, ticker symbols, regulators, indices, and monetary amounts, which general-purpose models flatten into one label or miss entirely. The better of two fine-tuned transformers scores 0.921 F1 on a held-out test set.
A chat agent on this site that answers recruiter and client questions about my work. Claude tool use over the site's own data, so every answer traces back to something on the page. Runs on a Cloudflare Worker with an origin lock, rate limiting, a bounded tool loop, and tests for each guardrail, plus an eval suite for hallucination and prompt-injection cases.
A suite of twelve free developer and productivity tools that run entirely in the browser: no login, no upload, nothing leaves the machine. One Next.js app covering JSON and XML formatting, image compression, QR codes, password generation, and more.
Live exchange rate tracker comparing USD, EUR, GBP and more across 11 Sri Lankan banks, powered by Python scrapers with hourly updates and rate history.
News aggregation platform for Sri Lanka. An Angular front end over a Spring Boot backend that ingests feeds on a schedule with Spring Batch, persists to MongoDB, and caches hot reads in Redis.
Full-stack point of sale system for managing customers, items, and orders, built with an Angular front end and a Spring Boot REST API.

Google's headline Flash rate is promotional and reverts on 1 January 2027. We ran three real workloads through the change, and found a second, sharper problem hiding above 200K tokens on Gemini 3.1 Pro.
An image tool that worked exactly once, then failed on every adjustment. The file format was innocent. A cleanup effect keyed on the URL it revokes was destroying its own source image.
DebuggerMeSatori throws this error when a div has one child, not just when it has several. Here is the actual rule, the four cases where the message misleads you, and what each workaround costs.
