Three core engineering disciplines to take an idea from architecture to high-performance production.
Full-stack web engineering tailored to your business: from high-converting marketing sites and booking platforms to complex multi-language web portals built with Next.js, React, and Tailwind CSS.
B2B sales research and data automation covers end-to-end data pipelines for industrial manufacturers and B2B enterprises: discovering prospect companies, filtering non-target retail noise, deduplicating records across multiple keys, and exporting verified Excel/CRM datasets ready for outreach.
When off-the-shelf software doesn't fit your operational model, I build bespoke cloud-based web applications: from barcode inventory management and cash reconciliation to multi-role access control and live analytics.
Turning your product concept into a high-performance mobile application running smoothly on both iOS and Android. Handling everything from UI/UX design and API integration to App Store and Google Play submissions.
Empower your operations with intelligent automation: from 24/7 conversational WhatsApp agents and document retrieval-augmented generation (RAG) to autonomous back-office task automation and CRM sync.
Direct Technical Ownership
You collaborate directly with the engineer building your system. From architecture and UI design to backend APIs and deployment, eliminating communication breakdowns and bloated agency overhead.
Built for Real Business Impact
Every project in this portfolio represents a live product or operational system. From multi-language platforms with localized URLs to customized inventory workflows, I prioritize systems that generate leads and streamline daily operations over aesthetic superficiality.
Technical SEO & Performance First
Clean semantic HTML, sub-second TTFB, schema.org structured data, hreflang, and canonical tags are baked into the core architecture from day one—not tacked on as an afterthought.
Predictable Scope & Transparent Pricing
Every deliverable, milestone, and timeline is documented in a written specification before development begins. No surprise invoices; out-of-scope requests are discussed transparently with agreed estimates.
Pragmatic AI & Automation
Instead of chasing buzzwords, I apply automation and AI where it eliminates real operational friction—such as RAG document intelligence, automated lead enrichment, or customized point-of-sale workflows.
Reliable Post-Launch Support
Delivering production code doesn't end our relationship. Every client gets post-launch monitoring, warranty periods, and clear channels for future updates and technical maintenance.
A clear, predictable four-step process from initial discovery to production launch.
We start with an initial technical consultation via Google Meet or WhatsApp. We discuss your business goals, target users, system constraints, and budget expectations with zero sales pressure.
I document our discussion into a clear engineering roadmap: deliverables, architecture decisions, milestones, and a fixed cost estimate. Code is written only after you approve the plan.
You receive regular staging builds to inspect real progress. We test and iterate collaboratively at major milestones, ensuring complete visibility into the codebase.
Following thorough QA, performance optimization, and SEO verification, your system goes live on production infrastructure. Post-launch support and documentation are included.
I am Ahmet Mert Yiğitbaşı, a software engineer based in Antalya, Turkey. I engineer high-performance web applications, custom software platforms, and AI solutions, guiding projects from technical architecture to production deployment. Writing clean code is only half the job—deeply understanding your business goals and operational bottlenecks is what delivers lasting impact.
More about my backgroundI am a full-stack software engineer based in Antalya, Turkey. I engineer high-performance web applications, custom software platforms, and data/AI automation systems for businesses, founders, and enterprises globally.
I specialize in end-to-end full-stack software development: custom cloud dashboards, barcode point-of-sale systems, cross-platform mobile apps for iOS and Android, and complex data harvesting pipelines, managing every layer from architecture to deployment.
I engineer practical AI workflows: 24/7 conversational customer assistants via WhatsApp, Retrieval-Augmented Generation (RAG) over internal business documents, and automated ETL pipelines that collect, clean, and deduplicate B2B prospect data.
Yes. While based in Antalya, I work remotely with clients across Europe, the US, and Turkey. Project communication is conducted via Google Meet, WhatsApp, email, and Loom with clear milestone tracking.
My portfolio includes multi-language industrial export websites, community portals with verified business directories, offline-capable POS software (EsnafPOS), location-intelligence competitive tools, and financial document RAG systems. You can explore all case studies on the Work page.
Absolutely. I frequently assist teams in redesigning legacy applications, migrating to modern Next.js/React architectures, speeding up slow databases, or fixing core technical SEO issues.
You can reach out through the contact form or send a direct message on WhatsApp. We'll arrange an initial technical consultation to define your requirements, timeline, and preliminary architecture.
Yes. Production delivery includes a warranty period, and I offer continuous technical maintenance packages for updates, security patches, and feature additions.
