04 / Delivery Methodology

A Structured, Transparent Working Process

Clear checkpoints at every stage. No hidden costs, no vague requirements, and no over-promising on delivery.

01 / PHASE 1

Inquiry & Honest Scoping

We discuss your specific business challenge in plain English. If your project is within my current delivery capabilities, we proceed. If it requires specialized infrastructure outside my scope, I will tell you directly rather than over-promising.

CHECKPOINT: Requirement feasibility confirmed
02 / PHASE 2

Specification & Fixed Scope

I prepare a clear, written specification outlining exact deliverables, architecture, and milestones. You know precisely what is being built before any code is written, preventing scope creep and unexpected delays.

CHECKPOINT: Written scope approved by you
03 / PHASE 3

Working Prototype & Visual Review

You review a working interactive prototype or layout before final production. This allows you to test navigation, verify typography, and give feedback early when adjustments are easy and risk-free.

CHECKPOINT: Prototype reviewed & confirmed
04 / PHASE 4

Engineering, Testing & Polish

I implement the approved scope with clean, semantic code, rigorous mobile testing, WCAG contrast verification, and speed optimization. Every feature is verified before presentation.

CHECKPOINT: Sub-second performance & zero errors
05 / PHASE 5

Deployment, Handover & Walkthrough

Your project is deployed to fast, reliable global edge hosting with free SSL, or integrated with your live API keys. I provide complete source code ownership and a personal walkthrough explaining how to use and update your system.

CHECKPOINT: Full ownership & live deployment

05 / The Engineering Dossier

Systems Architecture & Technical Case Studies

A technical record detailing software architecture, industrial concurrency, and local AI orchestration. Designed for engineering managers, senior recruiters, and technical peers.

CONFIDENTIALITY & ETHICAL DISCLOSURE

In strict adherence to professional non-disclosure agreements, commercial projects omit proprietary source code, internal schemas, client names, and confidential hardware details. Analyses examine high-level architectural design patterns, communication protocols, and system constraints.

All commercial case studies presented evaluate generalizable systems architecture, concurrent data pipelines, and open protocols (such as Modbus TCP/IP and Model Context Protocol) from employment-related engineering at Kitron. No proprietary production code, internal database schemas, company telemetry, or hardware designs are hosted or disclosed. Case study 03 represents an independent, open-architecture working prototype.

CASE STUDY 01 EMPLOYMENT-RELATED / ARCHITECTURAL ANALYSIS

Local AI Assistant Runtime with Model Context Protocol (MCP)

Architecting a privacy-preserving, local large-language-model assistant within an enterprise ASP.NET application using the Model Context Protocol to decouple AI reasoning from business tool execution.

C# / .NET ASP.NET MVC Model Context Protocol (MCP) Ollama Local LLMs JSON-RPC

1. Operational Problem & Constraints

Enterprise users required natural-language capabilities to query application state, execute specialized workflows, and generate summaries. However, two non-negotiable constraints ruled out standard cloud AI approaches:

Strict Data Residency: Internal corporate telemetry and operational records could not be transmitted to public cloud LLM APIs due to strict data privacy policies.
Determinism & Control: Model responses had to interface with existing .NET backend logic through secure, verifiable boundaries without granting unchecked database access.

FIGURE 1.1 — SYSTEM DATA FLOW & PROTOCOL BOUNDARY

2. Key Technical Decisions & Architectural Trade-Offs

Local Quantization via Ollama

Selected local inference over cloud APIs to ensure 100% data residency on premises. The trade-off was managing hardware compute constraints and ensuring model quantization stayed within host memory boundaries.

Model Context Protocol (MCP)

Adopted the open MCP standard to decouple LLM reasoning from tool execution. The application exposes discrete tools with JSON schema validation, preventing arbitrary code execution and making tool capabilities pluggable.

Asynchronous Streaming

Integrated asynchronous stream pipelines between the Ollama HTTP/RPC interface and the ASP.NET controller, preventing worker thread exhaustion during lengthy generation tokens.

3. Testing & Status

The system was verified through automated test suites evaluating tool invocation precision, schema adherence, and latency behavior under varying system memory loads. A working prototype was successfully demonstrated and tested internally.

CASE STUDY 02 EMPLOYMENT-RELATED / ARCHITECTURAL ANALYSIS

Real-Time Through-Hole Technology (THT) Automated Optical Inspection

Engineering high-speed, multi-threaded .NET inspection software interfacing with industrial camera hardware and factory PLCs over Modbus TCP/IP under strict manufacturing cycle times.

C# / .NET Industrial Camera SDKs Modbus TCP/IP Multi-Threading Factory PLCs Hardware Synchronization

1. Operational Problem & Constraints

Manufacturing assembly lines require real-time verification of printed circuit board assemblies (PCBA) to detect component presence/absence and mechanical alignment before soldering. The system operated under exacting physical constraints:

Conveyor Cycle Synchronization: Inspection had to execute deterministically within conveyor line cycle times without stalling the manufacturing flow.
Zero Tolerated Memory Leaks: Industrial software runs continuously for 24/7 manufacturing shifts; uncollected memory or frame buffer bloat would cause downtime.
Hardware Reliability: Any packet dropped over Modbus or missed camera trigger required immediate fail-safe handling to prevent uninspected boards from advancing.

FIGURE 2.1 — CONCURRENT HARDWARE & SOFTWARE PIPELINE

2. Key Technical Decisions & Architectural Trade-Offs

Modbus TCP/IP Packet Framing

Selected Modbus TCP/IP over proprietary fieldbus systems for robust, direct socket communication with the factory PLC, ensuring standardized bit-level register reads/writes.

Producer-Consumer Threading

Implemented a decoupled thread model using bounded thread-safe queues. High-speed image acquisition runs on a priority thread, feeding a processing pool without blocking the hardware frame grabber.

Memory Allocation Discipline

Pre-allocated memory buffers for incoming image frames to prevent Garbage Collector (GC) pressure from causing transient micro-stutters during high-cadence production runs.

3. Testing & Status

Verified in hardware integration test environments with synchronized trigger pulses and test PCB assemblies to confirm stable Modbus communications and deterministic pass/fail execution.

CASE STUDY 03 INDEPENDENT WORKING DEMONSTRATION & PROTOTYPE

Lightweight Web Billing & Automated Invoice Tool

Developing a client-side invoice generator that compiles itemized, tax-accurate PDF documents instantly without server infrastructure or recurring subscription overhead.

Modern Web Stack Vanilla JavaScript Client-Side PDF Engine Webhooks State Storage Zero Server Cost

1. Operational Problem & Constraints

Small independent businesses and freelancers frequently struggle with cumbersome billing workflows: typing invoices manually in Word, making calculation errors, and being priced out of expensive monthly accounting subscriptions.

Zero Operating Overhead: Must function without an expensive server backend, keeping deployment and hosting costs at $0.00.
Privacy-First Document Compilation: Customer financial details remain strictly in local browser memory rather than being stored on third-party servers.

FIGURE 3.1 — DOCUMENT LIFECYCLE & CLIENT-SIDE COMPILATION

2. Key Technical Decisions

Client-Side Blob Generation

Leverages the browser's native Canvas/Blob compilation APIs to render exact millimeter-accurate vector PDFs, eliminating server compute costs.

Structured Data Schema

Employs a clean, strict JSON data structure allowing invoices to easily sync with Google Sheets or trigger WhatsApp notifications via webhooks.

Zero Dependency Overhead

Keeps runtime dependencies minimal to ensure instant cold-start loading even on low-bandwidth mobile connections.

3. Testing & Status

Tested across Chromium, Safari, and Firefox viewports to verify print accuracy, responsive form layout, and calculation precision. Functioning demonstration prototype.
