⚙️ My Engineering Journey — Impact & Technical Modules ⚙️ मेरी इंजीनियरिंग यात्रा — प्रभाव और तकनीकी मॉड्यूल
Author’s Perspective लेखक का दृष्टिकोण
I have built and launched production-grade full-stack systems that prioritize measurable outcomes: SEO-first SSR, high-performance serverless backends, and pragmatic mobile clients. This page documents my engineering journey — the architectural choices I made, exact setup and deployment steps, operational instrumentation, the technical problems I faced and resolved, and the engineering lessons I carry forward. मैंने उत्पादन-स्तर के फुल-स्टैक सिस्टम तैयार किए और लॉन्च किए जिनका फोकस मापनीय परिणामों पर रहा: SEO-प्रथम SSR, उच्च-प्रदर्शन सर्वरलेस बैकएंड और व्यावहारिक मोबाइल क्लाइंट्स। यह पृष्ठ मेरी इंजीनियरिंग यात्रा का दस्तावेज़ है — मैंने जो आर्किटेक्चरल चुनाव किए, सेटअप और डिप्लॉयमेंट के सटीक चरण, ऑपरेशनल इंस्ट्रूमेंटेशन, जिन तकनीकी समस्याओं का सामना किया और उन्हें कैसे हल किया, और वे इंजीनियरिंग सबक जो मेरे साथ हैं।
This document is a case study and a reproducible technical guide, organized around: यह दस्तावेज़ एक केस स्टडी और पुनरुत्पाद्य तकनीकी गाइड दोनों है, जो निम्न बिंदुओं के चारों ओर व्यवस्थित है:
- Architecture & design decisions आर्किटेक्चर और डिज़ाइन निर्णय
- Tech stack and rationale (Kotlin, Python, LangChain, Gemini, AWS, Docker, CloudWatch) तकनीकी स्टैक और तर्क (Kotlin, Python, LangChain, Gemini, AWS, Docker, CloudWatch)
- Setup, build & deployment commands (CI/CD recipes) सेटअप, बिल्ड और डिप्लॉयमेंट कमांड (CI/CD नुस्खे)
- Operational metrics & monitoring (performance, errors, cost) ऑपरेशनल मीट्रिक्स और मॉनिटरिंग (प्रदर्शन, त्रुटियाँ, लागत)
- Problems encountered, root causes, and fixes सामना की गई समस्याएँ, उनके कारण और समाधान
- Trade-offs, alternatives considered, and why सोचे गए ट्रेड-ऑफ और विकल्प, और कारण
- Actionable engineering lessons for future projects भविष्य के प्रोजेक्ट्स के लिए लागू-योग्य इंजीनियरिंग सबक

Overview अवलोकन
My work is guided by three engineering priorities: precision, measurable impact, and scalable reliability. I focus on performance (Core Web Vitals, LCP/TTFB), observability (structured logs, CloudWatch), secure secrets handling, and pragmatic cost-efficient serverless patterns. Client apps are designed for real users — small APKs, offline support, and resilient UX on mid-range devices. मेरा कार्य तीन इंजीनियरिंग प्राथमिकताओं द्वारा निर्देशित है: सटीकता, मापनीय प्रभाव, और स्केलेबल विश्वसनीयता। मैं प्रदर्शन (Core Web Vitals, LCP/TTFB), अवलोकन (स्ट्रक्चर्ड लॉग, CloudWatch), सुरक्षित सीक्रेट हैंडलिंग, और व्यावहारिक लागत-प्रभावी सर्वरलेस पैटर्न पर ध्यान देता हूँ। क्लाइंट ऐप्स वास्तविक उपयोगकर्ताओं के लिए डिज़ाइन किए जाते हैं — छोटे APK, ऑफ़लाइन समर्थन और मध्यम-श्रेणी के डिवाइसों पर मजबूत UX।
Selected outcomes documented across projects: 1.5M+ organic impressions for an SSR blog in one month; 100/100 Lighthouse via CDN & caching; and a 3× increase in leads for a regional insurance platform. Each case includes deployment recipes, CI/CD steps, and instrumentation so results are reproducible. प्रोजेक्ट्स में दर्ज किए गए चुने हुए परिणाम: SSR ब्लॉग के लिए एक महीने में 1.5M+ ऑर्गेनिक इंप्रेशंस; CDN और कैशिंग के जरिए 100/100 Lighthouse; और एक क्षेत्रीय इंश्योरेंस प्लेटफ़ॉर्म के लिए 3× लीड वृद्धि। हर केस में डिप्लॉयमेंट रेसिपी, CI/CD चरण और इंस्ट्रूमेंटेशन शामिल हैं ताकि परिणाम दोहराए जा सकें।
If you are a hiring manager or technical interviewer, this section shows: the problems I choose to solve, the engineering trade-offs I make, concrete performance and availability results, and the reproducible steps to evaluate or extend each system. यदि आप एक हायरिंग मैनेजर या तकनीकी इंटरव्यूअर हैं, तो यह अनुभाग दिखाता है: मैं किन समस्याओं को हल करना चुनता हूँ, मैं कौन-से इंजीनियरिंग ट्रेड-ऑफ करता हूँ, ठोस प्रदर्शन और उपलब्धता के परिणाम, और प्रत्येक सिस्टम का मूल्यांकन या विस्तार करने के लिए दोहराने योग्य चरण।
