Hello, I'm

Andrew
Yalcin.

Software Developer  ·  VDC Specialist

I build custom applications that turn painful, manual workflows into clean, usable software. My background spans production web apps, API integrations, and 3D model coordination on large-scale construction projects, including a Meta data center campus.

Domain expertise meets
software engineering

Hi. I'm a software developer and construction technology specialist based in Texas, and I tend to do two things at once.

For the past few years, I've been working as a Senior VDC Specialist, coordinating 3D models across large-scale construction projects. Most recently, that means managing model environments on an $800M Meta data center campus in Temple, TX. Before that: a $360M state emergency operations center, a $180M university research building, and several others across Texas.

I find workflows that are painful by default and build something better.

In parallel, I've been building software through Rynost, my technology consultancy. The clients are mostly in construction and real estate. The work ranges from React web tools to API integrations that replace hours of manual research with a single clean result.

I'm now looking for a software engineering role where I can bring that same problem-first approach at scale.

Where I've worked

2025 - Present
Construction Technology Consultant
Rynost, Technology Consultancy

Independent consultancy focused on construction technology strategy and custom software development. I advise clients on technology adoption, identify high-friction workflows, and build production web applications to solve them.

Used 3D scanning to capture existing conditions of a client's commercial space, produced an as-built model and proposed design, then delivered a cost estimate the client used to negotiate a higher tenant improvement allowance with their landlord
Designed and shipped a React-based XML generator that automates Navisworks Clash Detective configuration, cutting hours of manual test setup to under a minute
Built a compliance verification tool that cross-references SBA HUBZone and FEMA flood hazard APIs in real time, returning a single pass/fail result to federal contractor compliance teams
Delivered an interactive property dashboard (Leaflet + Google Maps API) that pre-screened 58 compliant commercial sites for a client, replacing weeks of manual research
React Python JavaScript Leaflet REST APIs 3D Scanning Revit XML
2023 - Present
Senior VDC Specialist
JE Dunn Construction, Vaughn Construction, and others

3+ years of VDC (Virtual Design & Construction) coordination across multimillion-dollar commercial and hyperscale infrastructure projects. I've led model-based workflows from design through construction, spanning clash detection, 4D scheduling, prefab coordination, and field data capture.

Coordinating 3D models across structural, MEP, and architectural disciplines on a hyperscale Meta data center campus at JE Dunn, identifying and resolving spatial conflicts ahead of construction
Led clash coordination on 6+ projects totaling up to $360M at Vaughn Construction, mitigating field conflicts through proactive model-based resolution
Built 4D construction timelines to visualize sequencing and communicate schedule risk across project teams
Generated accurate as-built models using LiDAR scanning and point cloud data, minimizing rework on renovation projects
Automated data extraction and database workflows using Python, boosting shop management efficiency by 30% on a $300M semiconductor project
Produced fabrication-ready shop drawings and coordinated with prefab teams to align model geometry with field conditions

Applications built for real problems

Live Tool
Problem: Hours of XML setup, error-prone by hand
Clash Test Generator

VDC coordinators spend hours manually configuring clash detection tests across dozens of model files. This React app auto-detects disciplines from file names, renders an interactive test matrix, and generates ready-to-import Navisworks XML, reducing setup from hours to under a minute.

Live Tool
Problem: Two government portals, one compliance question
HUBZone + Flood Zone Verifier

Federal contractors must keep their principal office inside SBA HUBZone boundaries and outside FEMA flood zones, two separate datasets with no combined lookup. This tool cross-references both APIs in one query and returns a clear compliance result, eliminating a manual multi-portal process.

Client Work
Problem: Weeks of research to find one compliant address
HUBZone Relocation Dashboard

A Houston-based HUBZone contractor needed to relocate without losing federal certification. This interactive Leaflet map pre-screened 58 commercial properties that passed both HUBZone and flood-zone requirements, with street-view imagery and one-click property search, replacing weeks of manual cross-referencing.
