01

How I work, and what I take on.

I'm a Full-Stack Engineer and Engineering Lead with 6+ years building systems that move money and verify people: payments, billing, KYC and compliance, and the infrastructure underneath them.

Most recently I was a Staff Software Engineer at TechPassport, a London RegTech platform, where I owned the monetization stack end to end. I built it from scratch: Stripe integration, subscription management, and the full billing schema. I also cut API response times by 75 to 80% across the platform's critical endpoints, and I ran the design-to-engineering pipeline in Figma, shipping features from concept to production.

Before that I spent two years at Vested Finance, an investment platform handling live investor funds. I joined as a Software Engineer and was promoted twice in 12 months to Engineering Lead, running the KYC/Compliance and Premium Management squads as de facto product owner. We took onboarding from a single market to global users and unified subscription billing across Stripe, Razorpay, Google Play, and Apple in-app purchases.

Outside work I build with LLMs (tool calling, RAG, agents, MCP) and have mentored 1,000+ developers as a Subject Matter Expert.

I own systems end to end: schema design, API contracts, third-party integrations, performance work, and the on-call that follows. Most of it has been in regulated environments where every change is audited, so I default to idempotent writes, explicit state transitions, structured logging, and tests that prove the numbers reconcile. The same defaults hold whether the system moves money, streams game state, or calls a model.

02

Different domains, same discipline.

Four system walkthroughs. Signature verification, idempotency keys, double-entry posting, region routing, server-authoritative state, and deterministic compute. Illustrative sequences, not live systems.

Signature check, idempotency, then a double-entry posting. The parts that decide whether the money is right.

03

Systems I built and owned, end to end.

Eight pieces of production work on platforms handling live investor funds and regulated onboarding. Every number here is one I shipped.
Payments01

0 to 1

billing schema, Stripe, subscriptions

Monetization stack from zero

TechPassport

ContextThe platform needed a monetization layer and none existed.

DidDesigned the billing schema, integrated Stripe, and built subscription management. I architected it from scratch and own it end to end.

OutcomeTechPassport's complete monetization stack, built and run by one owner.

Performance02

75-80%

response time reduction

75 to 80% faster APIs

TechPassport

ContextCritical, high-traffic endpoints were too slow.

DidCaching strategies, query optimization, and async refactoring across the hot paths.

OutcomeResponse times down 75 to 80% on the endpoints that matter most.

Product engineering03

D3.js

relational data visualization

Configurable supplier workflows and relational visualizations

TechPassport

DidBuilt buyer-driven dynamic forms so supplier workflows can be configured per buyer, and complex relational data visualizations in D3.js.

OutcomeExpanded the product's core analytical capabilities.

ContextOnboarding only worked for a single market.

DidIntegrated alternate KYC providers and built region-aware compliance and verification flows.

OutcomeOnboarding opened to global users, unlocking the platform's international expansion.

FinTech06

Live funds

Money movement on live investor funds

Vested Finance

DidShipped payment processing, ledger systems, and curated multi-asset investment collections on a platform handling real investor money.

OutcomeProduction money-movement features where correctness is non-negotiable.

Billing07

One billing layer, four providers

Vested Finance

DidUnified subscription management across Stripe, Razorpay, Google Play, and Apple in-app purchases.

OutcomeA single subscription model across web and mobile.

Leadership08

Leading without a PM

Vested Finance

DidLed the KYC/Compliance and Premium Management squads as Engineering Lead and de facto product owner. Scoped roadmaps, ran delivery end to end, and owned the platform's entry-point flows. Set technical direction for a 5+ engineer squad inside a 15+ member cross-functional team: system design documents, query optimization, structured logging, and internal training.

OutcomePromoted twice in 12 months; recognized with the company's "Owning the Problem" award (Jan 2023).

Crypto Trading App

A Solana terminal that settles on mainnet

A Solana trading terminal that executes real swaps on mainnet. Not a paper-trading simulator.

Discovery and analysis: trending tokens from live market data (Birdeye), token search (DexScreener), OHLCV candlestick charts, a live swap feed, holder concentration, on-chain safety heuristics (mint and freeze authority, liquidity depth, pair age), and optional OpenAI risk summaries.

Execution: the server fetches Jupiter quotes and builds unsigned versioned transactions. The user signs with a Privy embedded wallet in the browser. The transaction is broadcast over RPC and confirmed on-chain. API keys stay server-side.

There is no application database. Market state comes from providers and balances live on-chain.

Game Night

Real-time party games, one room code away

Real-time multiplayer party games in a browser tab. One person creates a room, everyone else types the five-letter code, and the table plays on their own phones. No download, no account.

An authoritative Node and Socket.IO server sends per-player state snapshots, so no client ever holds information its player should not see.

The client is a zero-build vanilla JavaScript PWA. Five games ship with it, including social deduction, a co-operative counting puzzle, and an AI-judged rule-guessing game.

LLM game logic is hardened against prompt injection, and 232 end-to-end checks drive real socket clients against the server.

Investor Copilot

Private markets, answered in plain language

A conversational assistant for private-markets investors. Ask about holdings, MOIC, DPI, RVPI, fees, capital calls, distributions, and statements in plain language.

The core design rule: the model never invents a number. OpenAI tool calling handles intent and data access, all financial math runs in a deterministic compute layer over structured ledger data, and every answer returns the source rows plus a calculation trace.

It handles multi-currency reporting (USD, GBP, EUR, AED), multi-round positions, partial capital calls, write-offs, down rounds, and partial secondaries.

A golden-number eval suite verifies the compute layer without any model calls.

Skip the scrolling. Ask the page.

An assistant grounded in the facts on this page, built the way I build them: it answers from a fixed source, it will not invent a number, and when it does not know, it says so.
07

Agents move faster. I still sign off.

AI is part of the toolchain, not a substitute for judgement. Agents draft, run passes and automate the repeatable work. The spec, the review, and the calls that are expensive to get wrong stay with me.
  1. 01

    I write the spec

    Before any code, I write the spec myself: what the system does, what it must not do, and how I will know it works. It is version controlled and it is the contract. The agent plans against that, not a prompt I typed once.

    • Spec Kit
    • specify
    • plan
    • tasks
  2. 02

    Agents draft, I review every diff

    Agents run the implementation passes. I read every diff line by line the way I review a pull request, and nothing merges that I cannot explain. Different agents suit different passes, so I move between them.

    • Claude Code
    • Codex CLI
    • Cursor
  3. 03

    I teach it once, then reuse it

    I author the Skills that package expertise for a repeated task. MCP servers and connectors give the agent scoped access to the systems it needs. Plugins bundle the lot so a workflow travels with the repo.

    • Skills
    • MCP
    • Connectors
    • Plugins
  4. 04

    Context lives in the repo

    The rules I set sit in AGENTS.md and CLAUDE.md, committed next to the code. Specs and session transcripts land as markdown, so the reasoning behind a decision survives the chat window and is reviewable months later.

    • AGENTS.md
    • CLAUDE.md
    • transcripts
  5. 05

    The repeatable parts run themselves

    Once a flow stops being interesting it becomes an n8n workflow or a CI job, with the checks that catch it when it drifts. Anything I have done by hand three times is a candidate.

    • n8n
    • GitHub Actions

What never gets delegated
