AI Engineer / Software Engineer

I build LLM-powered products end to end — from transformer NLP pipelines and RAG systems to the containerised services and production interfaces that ship them.

Full ML lifecycle, from notebook to production

I'm an AI and Software Engineer with an MSc in Artificial Intelligence (Merit) from Queen Mary University of London and hands-on experience building LLM-powered applications, transformer-based NLP pipelines and cloud-deployed AI services.

Most recently I've been the sole frontend engineer on a production compliance platform for UK higher-risk residential buildings, shipping 100+ routes to pilot go-live. Alongside that I'm developing an autonomous multi-agent job search platform using RAG, vector search and LangGraph.

I work comfortably across the whole lifecycle — data normalisation, model fine-tuning, containerised deployment and CI/CD with Python, GPT-4, AWS and Docker — and I care a lot about verifying what I ship rather than assuming it works.

100+ Routes shipped on a live compliance platform
92% Accuracy on an NL-to-SQL pipeline built with GPT-4 and spaCy
50% Release time cut via Dockerised AWS deploys and GitHub Actions
23 Buildings live at pilot go-live

    Lead Design Engineer

    Blocvue · London

    • Sole frontend engineer on a production compliance platform for UK higher-risk residential buildings, building and shipping the web application to pilot go-live across 23 buildings.
    • Designed and built the platform's design system from scratch — shared components, design tokens and a written design brief adopted as the team's specification of record.
    • Built 100+ routes in Next.js 15, React and TypeScript covering document registers, statutory obligations, risk assessments, asset registers and role-based access.
    • Led a 54-item UI audit and remediation programme, taking each issue from discovery through implementation and verification with code-level evidence.
    • Diagnosed and fixed platform-wide defects including 24 broken form navigations, unsaved-work loss, containerised session failures and cache revalidation issues.
    • Identified and escalated a database-layer authorisation gap during a permissions audit, documenting remediation before pilot data entry.

    Software Engineer

    StatusNeo · India

    • Engineered an end-to-end NL-to-SQL pipeline with GPT-4 and spaCy NER, letting non-technical teams query relational databases in plain English at 92% accuracy across finance and healthcare query sets.
    • Presented technical architecture and model performance findings to non-technical stakeholders, translating NLP pipeline behaviour into business-impact terms that informed product decisions.
    • Optimised a RandomForestClassifier via GridSearchCV, reducing model error by 15% and processing time by 20%; deployed on AWS via Docker with a GitHub Actions CI/CD pipeline, cutting release time by 50%.

Things I've built

June 2026 — July 2026

AI Job Application Copilot

An AI-powered job application platform combining LLMs, RAG, vector search and LangGraph multi-agent orchestration. Handles resume parsing, ATS optimisation, job matching, cover letter generation and live job discovery through external APIs.

A Sentence Transformers and Qdrant RAG pipeline powers semantic resume Q&A and contextual retrieval, wrapped in a human-in-the-loop lifecycle with approval workflows, status tracking and Playwright-based submission automation. Shipped full-stack on FastAPI, PostgreSQL, React and Docker Compose.
