/ experience

May 2026 — Present

Agentic AI Automation Engineer @ Omnicodes

Canary Wharf, London

  • Consulted with the founding team to scope and define an agentic lead generation automation, presenting technical architecture, API cost breakdown, and human-in-the-loop design before implementation began
  • Proposed and justified a single approval gate at the point of highest leverage, balancing throughput against quality control
  • Delivered the full system with documentation and a live walkthrough, enabling the team to operate the pipeline independently via Google Sheets

April 2026 — Present

Agentic AI Automation Engineer @ Assistosphere

London

  • Assessed the guest communications workflow, identified automation opportunities, and proposed a structured AI pipeline covering classification, drafting, escalation, and audit logging
  • Presented system architecture and API cost estimates before build; defined human oversight boundaries — no reply reaches a guest without operator approval
  • Deployed a live production agent handling guest messaging for a real London short-term rental property, with full Google Sheets audit trail and Slack approval gateway

February 2026 — March 2026

Junior Software Engineering Intern @ Oont

London

  • Implemented service-layer validation in a NestJS backend preventing products without images from being marked available
  • Built and executed a Node.js Firestore migration script targeting a non-default database instance, updating 16 production documents with a dry-run safety mode
  • Wrote Jest test cases covering validation rules, image-removal behaviour, and regression scenarios; resolved CI/CD failures before PR submission
  • Worked within a GitHub PR-based workflow with sprint planning, Jira task tracking, and code review cycles

Technical Sales Intern @ AI Growth Bureau

Consulting and technical sales role bridging AI solutions with client needs.

/ projects

LockedIn

Full-stack production AI accountability agent on Telegram — shipped in 2 weeks, 25 onboarded users and a paying customer within 48 hours of launch.

  • Engineered an LLM-driven conversational onboarding flow using Claude API, replacing a 594-line state machine with a 210-line prompt-driven system
  • Parallel async architecture running Telegram bot + FastAPI webhook server concurrently in one Python process (asyncio/uvicorn)
  • Real-time intent classification pipeline using asyncio.gather for simultaneous Claude API calls — response generation + silent activity detection
  • Behavioural mode engine with five dynamic states (HYPE, FOCUS, PRESSURE, ENFORCEMENT, RECOVERY) modulating tone in real time
  • Stripe Checkout integration with signature verification and unique activation codes
  • Per-user nudge scheduling via APScheduler with tone escalation logic
  • Dockerised with CI/CD via GitHub Actions, deployed to Railway

Prospekt

Fully async agentic lead generation pipeline — from business discovery to deployed demo site to cold outreach, triggered by a single API call.

  • Discovers local businesses via Google Places, scores web presence using Claude vision on Playwright screenshots, generates personalised demo landing pages, deploys via Vercel API, and dispatches cold outreach via Gmail
  • Two Google Sheets approval gates via long-poll loop — no webhook infrastructure required on the operator side
  • Inbound replies classified by Claude Haiku; interested leads escalated to Slack in real time
  • 11 discrete job states; pipeline triggerable via Slack slash command
  • Python 3.12
  • FastAPI
  • Claude Sonnet 4.6
  • Claude Haiku
  • Playwright
  • Supabase
  • Vercel API
  • Gmail API

Assistosphere Agent

Production AI guest messaging agent live on a London short-term rental property.

  • Polls Lodgify PMS for new messages, classifies intent across 6 categories via Claude Haiku, fetches property-specific details from Google Docs, and drafts contextual replies via Claude Sonnet
  • Built on the WAT framework (Workflows, Agents, Tools) separating probabilistic reasoning from deterministic execution; complaints escalated immediately with no draft sent
  • All replies routed through a Slack human-approval gateway; every interaction logged to Google Sheets
  • Python
