Supporting Repository for Resume Entry: Senior Platform Engineering Lab (GCP/Kubernetes R&D)
This repository documents a dedicated, systematic learning initiative to master the Go programming language, with a focus on core concepts essential for modern Platform Engineering and Infrastructure Automation (IaC). The goal is to build foundational knowledge necessary for developing high-performance, concurrent, and scalable systems tools (CLI utilities, API services, Kubernetes controllers).
The structure progresses from basic I/O and variable declaration through control flow, data types, and error handling, demonstrating a robust understanding of Go’s unique syntax and system-level capabilities.
| Environment | Detail |
|---|---|
| Operating System | Ubuntu 24.04 LTS |
| Golang Version | 1.22.2 |
The repository is organized to provide maximum transparency between code, execution, and troubleshooting.
| Folder | Description |
|---|---|
Code/ |
Contains foundational code and structured Go files, including data structures and type conversions. |
Scripts/ |
Contains various scripts focusing on I/O, variables, and control flow mechanics. |
Screenshots/ |
Visual evidence of all code execution and troubleshooting steps (referenced in the OPERATIONAL_LOG.md). |
OPERATIONAL_LOG.md |
Full, chronological, dated log of all tasks, outputs, and troubleshooting steps. |
The following sections organize the learning artifacts by logical concept, demonstrating progression from basic syntax to data structure manipulation.
| Date | File | Concept & Documentation |
|---|---|---|
| 2025-09-04 | good-evening.go, greeting.go |
Basic package declaration and I/O using fmt.Print/Println. Includes initial troubleshooting/debugging on comment syntax (# vs //). |
| 2025-09-06 | name-location-opinion*.go |
Demonstrates variable assignment, string interpolation, and I/O formatting (newline characters and fmt.Println). |
| 2025-09-07 | shorthand.go |
Usage of shorthand declaration (:=) for implicit type inference. |
| 2025-09-11 | outer_inner_blocks.go |
Exploration of variable scope and shadowing in outer and inner code blocks. |
| 2025-09-11 | zero_values.go |
Demonstrates default zero values for various data types (string, int, bool). |
| 2025-09-14 | variable_types_typeof.go |
Explicitly verifies variable types using the reflect.TypeOf function. |
| 2025-09-14 | int_to_float64.go, float64_to_int.go |
Demonstrates explicit type casting between numeric types. |
| 2025-09-14 | str_to_int_noerr.go, str_to_int_err.go |
Uses strconv.Atoi for string-to-integer conversion, including structured error handling and intentionally triggering errors to demonstrate error flow. |
| 2025-09-14 | constants.go, constants_error.go |
Defines typed and untyped constants, including demonstrating compile-time errors with mismatched constant types. |
| Date | File | Concept & Documentation |
|---|---|---|
| 2025-09-17 | comparison_operators.go |
Usage of all six comparison operators (==, !=, >, <, >=, <=) to return boolean values. |
| 2025-09-20 | arithmatic_operators.go |
Execution of basic mathematical operations (+, -, *, /, %). |
| 2025-09-26 | logical_operators.go |
Demonstrates logical operators (AND &&, OR ||, NOT !) in conditional contexts. |
| 2025-09-26 | assignment_operators.go, bitwise_operators.go |
Demonstrates all five assignment and bitwise operators. |
| 2025-09-28 | if_else_statements.go |
Implements conditional logic using if-else blocks. Includes troubleshooting on incorrect shorthand usage. |
| 2025-09-28 | switch_case.go |
Advanced usage of switch statements, including the use of fallthrough to execute subsequent case blocks. |
| 2025-09-30 | infinite_loop.go |
Basic structure of an infinite loop (which will be leveraged later for listeners/polling in system utilities). |
| Date | File | Concept & Documentation |
|---|---|---|
| 2025-09-30 | arrays.go |
Defines and manipulates single- and multi-dimensional (2D) arrays, including iteration using for loops and element assignment/replacement. |
