Work I’m proud to point at

A mix of shipped client systems and open personal projects. Client work is anonymized while it clears confidentiality review.

TaskFlow — a production-grade task manager, built in the open

TaskFlow — a production-grade task manager, built in the open

An authenticated project-and-task SaaS — Angular front to back against a Clean Architecture .NET API — built as an open portfolio piece rather than a client deliverable.

Suggu CLI — safe .NET workspace automation

Suggu is a cross-platform .NET 10 productivity CLI for creating, inspecting, and automating filesystem and .NET solution work. It combines guided workflows, diagnostics, static endpoint tracing, and project-owned rulebooks—useful directly in the terminal and as a reliable execution layer for Codex or Claude Code.

New service · SEO + GEO

Rank on Google. Get cited by AI.

Search is splitting in two. People still type into Google, but they also ask ChatGPT, Perplexity, Gemini and AI Overviews — and those answers cite a handful of sources. I make your site one of them.

Classic technical SEO for the crawler, generative engine optimization (GEO) for the model. Same site, two audiences, one engagement.

From $900
one-off audit + fix plan
From $750/mo
ongoing search + AI growth

Illustrative example, not live data.

What I work on

Six areas that move rankings and citations

  • Technical SEO & Core Web Vitals

    Crawlability, indexation, clean server-rendered HTML, and LCP / INP / CLS fixed on real devices. Crawlers and models both read the source, so the source has to be right.

  • Structured data & entities

    JSON-LD for Organization, Product, Service, FAQ and Article, plus consistent entity signals across the web so machines know exactly what you are and who you serve.

  • Content architecture

    Keyword and intent research turned into topic clusters, internal linking, and pages that match how buyers actually search — not a pile of unconnected blog posts.

  • Generative engine optimization

    Extractable answers, quotable statistics, clear definitions, llms.txt and crawler access for AI agents, so ChatGPT, Perplexity and AI Overviews quote your page instead of a competitor’s.

  • Multi-market & local reach

    Google Business Profile, city and region landing pages, review and citation hygiene, and hreflang for multi-market sites. Useful whether you sell in one city or five countries.

  • Measurement you can read

    Search Console, rank tracking and AI mention monitoring in one monthly report: what moved, what it earned, what ships next. No vanity dashboards.

The skills behind it

SEO that lasts is an engineering job as much as a marketing one. This is the toolkit I bring to it.

  • Core Web Vitals
  • Schema.org JSON-LD
  • Sitemaps & robots

How it works

A clear path from idea to launch

No black box. You always know what’s happening, what ships next, and what you’ll have in hand at each step.

  1. Discover

    We get clear on the problem, the users, and what success actually looks like before any code is written.

    Deliverable A short brief: scope, goals, and a fixed-price proposal.

  2. Plan

    I map the architecture, key screens, and milestones so you know exactly what ships and when.

    Deliverable Technical plan, timeline, and milestone breakdown.

  3. Build

    I build in reviewable increments with regular demos. No black box, no month-long silences.

    Deliverable Working software at every milestone, deployed to a preview URL.

  4. Launch & Support

    We go live with monitoring in place, and I stay available to fix, tune, and extend.

    Deliverable Production launch, handover docs, and a support window.

About

The person behind the work

I’m a full-stack developer who cares about the boring parts that make software trustworthy: correctness, performance, and clarity.

I’ve built role-based internal platforms, booking systems, and data-heavy web apps end to end, and I bring that production discipline to freelance work.

FAQ

Questions I hear often

If yours isn’t here, just ask. I’d rather answer up front than have you guess.

Most work is fixed-price against a clear scope, so you know the total up front with no hourly surprises. Retainers are billed monthly. I’ll always give you a firm number in the proposal before anything starts.

A marketing site is usually 2-4 weeks. An MVP web app is typically 6-12 weeks depending on scope. I share a milestone plan during the Plan phase so the timeline is never a mystery.

Technical fixes land immediately and Core Web Vitals improve the week they ship. Ranking and AI-citation movement is slower: expect early signals in 6–8 weeks and meaningful change by month three. Anyone promising page one in a fortnight is guessing.

Each milestone includes a round of revisions so we can adjust as we go. Larger changes outside the agreed scope are handled as a small change request rather than silently absorbed or refused.

Every project ships with a support window for fixes. Beyond that, I offer a retainer for ongoing development, performance work, and maintenance so your product keeps improving.

Yes. I regularly join existing codebases, follow your conventions, and work alongside your team via pull requests and your tools, not as an outsider throwing code over a wall.

I work with clients in any country. I’m based in IST (UTC+5:30) and shift my hours to overlap with yours, wherever you are. Expect regular written updates, calls scheduled in your working hours, and async demos so progress is always visible.

50% upfront to reserve the work and 50% on completion, or split across milestones for larger projects. Payments are in USD via Wise or Stripe, with a proper invoice for every stage.
