HOMEPAGE (https://yama.com) Mark Yamashita | Unity & Software Engineer
Senior Unity & Software Engineer [H1] Mark Yamashita I design and ship realtime systems, networking stacks, and tools that help teams build games and interactive products with confidence. View selected work View experience Download resume (PDF) Unity · C# · WebGL · gRPC Web · iOS [H2] What I focus on Architecting clean Unity UI and game systems for mobile, desktop, and WebGL. Building client-server systems, including APIs, gRPC-Web clients, REST integrations, and deterministic replay tools. Profiling and tuning frame rate, memory, and build size on constrained hardware. Creating editor tools, validators, and workflows that improve development speed and reliability. Prioritizing maintainable architecture with readable code, clear boundaries, and data flow that teams can extend. Building systems with debuggability in mind using structured logging, predictable behavior, and tools to reproduce complex issues. Designing APIs with clear contracts, validation at the boundary, and structured error handling. Picking up new domains quickly and delivering reliable systems across frontend, backend, and client platforms. [H2] Selected work [H3] PariMAX WebGL HHR Client 1/ST Technology · Unity · WebGL · gRPC Web Led development of PariMAX’s first Unity WebGL client for real money historical horse racing games. Built a reusable gRPC Web networking package with typed requests, retries, and structured logging used across titles. Converted a legacy Unity PC title to WebGL with build-size, performance, and cross-browser optimizations. Built the entire Unity gRPC-Web integration path using a custom JavaScript bridge, Webpack bundling, and .jslib interop. Collaborated with backend teams on secure, server-authoritative flows. [H3] WhoAmMAI Personal project · Cloudflare Workers · React · TypeScript · LLM integration LLM-powered daily guessing game exploring serverless APIs, structured model output, validation, and constrained game loops. Built a React web app with a Cloudflare Worker API. Designed structured JSON output boundaries for LLM intent parsing and response handling. Added API validation, structured error responses, and protected admin-route patterns. Designed API boundaries to separate parsing, validation, and game logic for maintainability. View GitHub repo [H3] BotBattle Personal project · Go backend · TypeScript frontend A competitive bot platform with a deterministic battle loop and replayable simulations. Designed as a way to deepen backend, API, and systems skills beyond game clients. Implemented a bot upload API with validation and structured error responses. Outlined the architecture for a seedable battle engine supporting reproducible matches and debugging. Designed a deterministic simulation model to enable reproducible matches and debugging. [H2] Experience Led Unity WebGL client development for real time HHR casino games, including PariMAX’s first WebGL title. Built and maintained a gRPC Web networking package reused across products. Created editor tools and validators that improved content workflows and data safety. Profiled and optimized frame rate and memory on constrained hardware. Implemented core systems for a 2D survival and colony game across PC and consoles. Worked on AI, animation, and performance tuning for large worlds. Built internal tools to speed up world generation and designer workflows. Created the TeachMe app series, reaching more than two million downloads. Modernized Aw Craps into a freemium title with improved purchase and restore flows. Prototyped a VR version of BC Blackjack for Meta Quest using Unity XR and OpenXR. [H2] Contact I am interested in roles where I can solve hard engineering problems across systems, backend, and mobile, building modern, efficient, and maintainable solutions. I love designing software that is robust, performant, and thoughtfully engineered, regardless of platform or language. Email: [email protected] LinkedIn: linkedin.com/in/markyama

Your Diagnosis
Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.
Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)
These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.
Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.
Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.
Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.
Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.
Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.
Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.

Blogs, Influencers & Personal Brands BS: Mark Yamashita (yama.com)
This is a forensic masterclass in zero-BS engineering documentation that prioritizes technical proof over personal brand narrative. It effectively utilizes specialized jargon as substance rather than fluff, providing a transparent and verifiable professional history. The only ‘BS’ present is the technical absence of structured data to bridge its claims to the semantic web.
Implement Person and CreativeWork JSON-LD schema to formally link projects like PariMAX and BotBattle to your identity. Replace the email protection 404 with a direct contact form or obfuscated mailto link to improve technical credibility. Add outbound links to the mentioned GitHub repositories and LinkedIn profile to increase the verified proof_links_count. Include specific date ranges for each role in the [H2] Experience section to anchor the timeline of technical expertise.
The site is classified under Blogs and Personal Brands, but it functions strictly as a technical Software Engineering portfolio. It ignores all industry-standard BS tropes like ‘thought leadership’ or ‘audience growth’ in favor of low-level systems engineering documentation.
“The score of 10 is driven primarily by the lack of technical schema and the lack of external verification links in the metadata. The site received 0 points for BS in Information Density, Semantic Coherence, and Commodity Fingerprint because it avoids almost every known pattern of professional fluff. This is a high-substance, low-signal-noise portfolio.”
This training module utilizes a snapshot of public data from Mark Yamashita, captured on May 24, 2026, to demonstrate how machine logic evaluates different types of business narratives.
Purpose: This data is presented under “Fair Use” / “Educational Exception” for the purpose of forensic semantic analysis, allowing users to compare human intuition against machine-generated evaluations.
