Build a product from scratch and ship it.
Give me a Figma or just an idea. I write the code, design the screens, wire up payments, deploy it, and keep it running. No handoffs, no gaps.

What I can do for you
Plain EnglishBe the only engineer a small team needs on the frontend.
One person who decides the architecture, writes the code, reviews the pull requests, talks to designers and backend, and unblocks everyone. Senior-level judgment without the politics of a big team.
What it looks likeAt Oboard I was this person for 4 years — reviewed every frontend change, owned the design system, and shipped the product into Monday, Salesforce, Jira and Confluence from one codebase.
Own a whole feature area, end to end.
From first conversation with stakeholders, through design and code, to QA and production. I talk directly to founders and C-levels — not just to engineers.
ProofOwned the OKR dashboard at Oboard for 4 years; reviewed 100% of frontend changes.
Add AI to your product without it being a gimmick.
I've shipped real AI features (OpenAI, Claude, Gemini) with search, chat, and context — the useful kind, not the demo kind. Plus the infra around it: queues, caching, cost control.

How I ship fast without cutting corners
My method · SDD
Spec-Driven Development
I built my own SDD framework on top of GitHub Spec Kit — and I ship with it.
Most teams either over-plan and never ship, or ship fast and break things. My framework forces every feature through a short, structured spec first — then AI tooling generates the scaffolding, tests, and first pass of code against that spec. Result: faster delivery, fewer bugs, real docs from day one.
This isn't theory — I dogfooded it to build My Zodiac AI solo and accelerated feature work at Soulwise. Same framework, two different contexts.

Most recent firstFull-Stack Engineer
Soulwise AI · AI-powered astrology platform (100k+ users)
- Made the app 36% faster to load (bundle shrunk from 250 KB to 160 KB) by splitting code smarter and loading translations only when needed.
- Cleaned up the codebase: full TypeScript strict mode across the project; reorganised the code into 14 clear feature modules and deleted 3,500+ lines of duplicates.
- Shipped native iOS and Android apps using Capacitor with one shared codebase — both live on App Store and Google Play.
- Built real AI features connecting OpenAI, Anthropic Claude, and Google Gemini, with a vector-search layer (Qdrant) so the AI has real context, not just vibes.
- Real-time updates and notifications via WebSockets and background queues (Redis + BullMQ), so users see changes instantly.
- Set up the testing + CI quality gates — Vitest for unit tests, Playwright for full end-to-end — so broken code can't reach production.
Senior Frontend Developer · Feature Owner
Oboard · B2B SaaS for company goal-setting (OKRs) · Team of 2 frontend + 5 backend engineers
- Owned a whole feature from idea to launch: the OKR dashboard and analytics. Talked directly with C-level execs about what to build next.
- Modernised the frontend across several major framework upgrades; was the primary reviewer on every frontend change for quality control.
- Shipped the product inside other platforms — Monday.com, Salesforce, Jira, and Confluence — so customers could use it where they already worked.
- Built the build pipeline that produces 5+ versions of the app from one codebase: standalone webapp, Monday embed, Salesforce app, Atlassian apps, and mobile.
- Integrated payments and subscription billing.
- Built 3+ internal tools for the QA and dev team during sprint gaps — cut repetitive manual work by roughly 40%.
- Mentored and reviewed across the frontend team; partnered with 5 backend engineers on API shape and data contracts.
