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.

01 — About

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

Where I've worked

  1. July 2026 — Present

    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.

    AI Data Processing Analyst (Contract)

    Sigma.AI DATA Ltd. · London

    • Enforced annotation protocols across large-scale speech corpora for ASR and NLP model training, escalating data quality issues to pipeline leads to maintain downstream model integrity across production datasets.

  3. Jan 2024 — May 2024

    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%.
