+## **Project Details**
+
+* **Project Title:** Spectra.jl across the electromagnetic spectrum  
+* **Mentors:** To be determined (OpenAstronomy/Spectra.jl)  
+* **Organization:** JuliaAstro / Spectra.jl
+
+---
+
+## **Why I am a Good Fit for This Project**
+
+I have spent significant time learning the **Julia language** and its benefits, such as **Multiple Dispatch** and **Composability**, which are essential for a package like Spectra.jl that must handle diverse data types (Radio, X-ray, Optical) under a uniform interface.
+
+I have a strong foundation in **FITS file structures**, having already grasped basic column terminology and the use of **FITSIO.jl**. My approach focuses on "avoiding the noise" and focusing on precision and robustness rather than high-volume, low-quality code. I am passionate about space-obsessed analysis and am eager to transition from "generating code" to "thinking like an astronomer".
+
+---
+
+## **Work Approach: The "Atomic PR" Method**
+
+A key challenge in open-source is reviewing massive Pull Requests. I commit to submitting all work in **atomic PRs**—small, manageable, and highly tested chunks. This ensures that work remains reviewable and robust, preventing the bottlenecks seen in previous years.
+
+---
+
+## **Proposed Work & Milestones**
+
+### **Phase 1: Core Integration & OGIP Parser (Weeks 1–6)**
+
+The goal is to provide a uniform interface for loading datasets and metadata by leveraging existing work in SpectralFitting.jl.
+
+* **Week 1-2: Enhanced FITS I/O & TDD Setup**  
+  * Establish a comprehensive test suite using **Test Driven Development (TDD)**.  
+  * Curate a library of spectral data samples for compatibility testing.  
+* **Week 3-4: OGIP Parser Migration**  
+  * Move and integrate the **OGIP (Office of Guest Investigator Programs) parser** from SpectralFitting.jl into Spectra.jl.  
+  * Ensure the parser correctly handles X-ray and Gamma-ray headers common in OGIP standards.  
+* **Week 5-6: Primary Spectral Type Implementation**  
+  * Implement data loading for a specific spectral datatype (e.g., X-ray or Optical).  
+  * **Deliverable (1st Evaluation):** Integrated OGIP parser and a working loader for the first chosen file format.
+
+### **Phase 2: Multi-Wavelength Framework & Routines (Weeks 7–12)**
+
+Expanding the library to support diverse electromagnetic ranges and common analysis manipulations.
+
+* **Week 7-8: Multi-Format Support**  
+  * Implement data loading for at least two additional file formats (e.g., Radio or Infrared spectra) to ensure the library handles different physics and instrument types.  
+* **Week 9-10: Common Analysis Routines**  
+  * Implement **Rebinning Heuristics**: Create functions to rebin data based on minimum flux, signal-to-noise ratio, or count rates.  
+  * Implement **Unit Conversions**: Support transformations between wavelength (Angstrom/nm) and energy (keV/eV) or frequency (Hz).  
+* **Week 11-12: Refinement & Documentation**  
+  * **Integration Testing:** Ensure cross-compatibility between loaders.  
+  * **Documentation:** Create a **Pluto.jl notebook** demonstrating the loading of a star's spectrum and performing a "first-look" analysis.  
+  * **Deliverable (Final Evaluation):** A revamped Spectra.jl with support for 3+ file formats and a robust rebinning/transformation API.

+
+## **Design Principles**
+
+* **Julia Idioms:** Use parametric types to handle different spectral ranges (Radio vs X-ray) without OOP overhead.  
+* **Composability:** Ensure Spectra.jl types "just work" with DataFrames.jl and plotting recipes.  
+* **Performance:** Utilize @views and in-place operations to handle large spectral datasets efficiently.

+
+## **Timeline Summary**
+
+| Week | Phase | Deliverable |
+| :---- | :---- | :---- |
+| **Pre-coding** | Community Bonding | Learn spectral data types (Radio/X-ray differences), explore SpectralFitting.jl internals. |
+| **1-2** | Phase 1 | TDD infrastructure and spectral data library curation. |
+| **3-4** | Phase 1 | OGIP Parser migration and integration. |
+| **5-6** | Phase 1 | First spectral datatype loader; **1st Evaluation**. |
+| **7-9** | Phase 2 | Implementation of 2+ additional file formats (Radio/Optical). |
+| **10-11** | Phase 2 | Rebinning heuristics and unit conversion routines. |
+| **12** | Phase 2 | Final cross-validation, Pluto notebook demo, and **Final Evaluation**. |

+## **My Recent Contributions**
+
+* **Stingray.jl:** Refactored plotting recipes and added test suites (\#72).  
+* **Stingray Notebooks:** Fixed ntrial calculation in Pulsar search notebook (\#125).  
+* **OpenAstronomy:** Alphabetized members list and improved student guide visibility.
+
+I am fully available during the GSoC coding period and will manage my academic load at Scaler School of Technology through proactive communication with my mentors.
