Computer Engineering Undergraduate | Full-Stack • Cloud/DevOps • IoT/Embedded • Security
First-Class Computer Engineering student (GPA 3.84) building scalable full-stack, IoT/embedded, and cloud-native systems with a security & reliability mindset.
About Me
My background and what drives me.
I’m a First-Class Computer Engineering undergraduate focused on scalable full-stack development, embedded/IoT, and modern cloud-native architectures. I care about security, reliability, and performance—turning low-level efficiency into clean, intuitive user experiences.
Key Highlights
Work Experience
Software Engineer Intern
WSO2 (Pvt) Ltd.
Main Project: Streaming Support for WSO2 Integrator AI Libraries. Designed and implemented first-class, token-by-token streaming across the Ballerina AI ecosystem (ballerina/ai core, connectors, and model providers), delivering an idiomatic streaming experience comparable to the Vercel AI SDK and LlamaIndex.
- Evaluated four architectural approaches and built a unified streaming abstraction, authoring Ballerina type definitions that standardize parsing of heterogeneous SSE events across 6+ LLM providers (OpenAI, Anthropic, Azure OpenAI, Mistral, DeepSeek, Ollama, OpenRouter), while extending the existing model-provider interface to preserve backward compatibility.
- Built Ballerina connectors, model providers, and embedding providers from scratch (including a new Google Gemini library) and resolved multiple production issues: added Claude Opus 4.7/4.8 support (#1612), fixed parallel tool-calling in the OpenAI and Azure OpenAI connectors (#1685, #1688), and patched Anthropic multi-round parallel tool calls (#1647).
- Prototyped an HR agent using RAG and MCP on the WSO2 Integrator, and authored design proposals and technical documentation.
Research
Current academic exploration and contributions.
Security Testing and Threat prediction for Wi-Fi 7 MLO
- Analyze Wi-Fi 7 MAC backoff mechanism across counter states to uncover protocol-level vulnerabilities
- Identify attack surfaces in Multi-Link Operation (MLO) and design mitigation strategies
- Current contribution: research gap analysis + GNN-based threat prediction implementation
