Two runtimes, one engineer

day.runtime09:00 — 18:00

By day — Junior Software Engineer

At Fibre2Fashion: shipped internal production AI systems end to end — a human-in-the-loop news discovery and drafting agent and a document-to-article pipeline — in Python + FastAPI, integrated into the company's existing ASP.NET admin portal. ASP.NET Core + SQL Server remains the day-to-day foundation, with Python for data pipelines and large-scale scraping. Currently rebuilding TexPro's Market Intelligence dashboard as a ground-up Angular 21 app — zoneless and signals-based — replacing the legacy front end module by module.

By night — Freelance Full-Stack

I ship production web products for founders and small teams — Next.js and React on Supabase, with Razorpay/Stripe payments, transactional email, and media pipelines. Tightly scoped, deployed on Vercel or Netlify, idea to live URL in weeks.

note: the two tracks share one spine — enterprise backend habits (budgets, access control, observability) applied to LLM systems, and modern product delivery applied to internal tools.

Human-in-the-loop story discovery & drafting agent

harvest → rank → confirm → draft

Replaces the editorial team's manual morning story hunt at a desk publishing 20–30 textile articles daily. Harvests ~65 primary and ~75 secondary curated source pages across 17 countries, scores and de-dupes candidates with an LLM, confirms each against its primary source, then drafts publish-ready copy — every stage streamed live over SSE.

AI Article GenFibre2Fashion · in production

Document-to-publish article pipeline

intake → structure → body → metadata → render

Turns a raw Word document into a publish-ready package — headline, key takeaways, table of contents, body, SEO metadata, FAQs — plus the DOCX, PDF and HTM artefacts the public site serves. Six phases, three JSON-mode LLM calls for a short article. Editorial rules live as fail-open SQL rows, so guidelines change without a code deploy.

Converted to full-time after the internship.
- Shipped a human-in-the-loop news discovery and drafting agent (Python, FastAPI, Playwright) that turns an editorial desk's manual morning story hunt into one click: it harvests ~65 primary and ~75 secondary sources across 17 countries, has an LLM score, de-dupe and rank a ~20–30 story shortlist, then drafts publish-ready copy for editor review.
- Cut article prep from retyping eight fields by hand to upload, review, save: a six-phase LLM pipeline turns a Word file into headline, takeaways, contents, body, SEO metadata and FAQs; editorial rules live in SQL and change without a deploy.
- Designed the shared LLM layer behind both: one interface over OpenAI (in production), Gemini and Claude with JSON output, retries, per-job token budgets and cost-tiered models; hosted on IIS inside the company's ASP.NET portal.
- Rebuilding TexPro's Market Intelligence dashboard as a ground-up Angular 21 app (zoneless, signals) from Figma designs; shipped the Sustainability module and streamed AI Insight panels on a shared Highcharts and virtualised-table layer.
- Removed a manual editorial step from a high-traffic news pipeline with an Azure OpenAI integration in .NET 6 that detects and masks sensitive financial figures in paid submissions before publication.
- Delivered Corporate Team Management for seat-based B2B subscriptions (REST APIs, PostgreSQL and SQL Server schemas, invite and payment flows) and automated per-client, multi-currency Excel reporting in C# and EPPlus.
