Software Engineer | Love to learn in public | Love open source projects | I just love swimming 🏊 #100Devs
- Today felt more like testing tools than writing code, but it’s all part of leveling up the workflow.

- Continued experimenting with prompting techniques while diving into Cursor’s documentation.
- Been using these so-called AI-powered editors lately — honestly, still figuring out which ones actually make you more productive
Day 58 of #100DaysOfCode #LearnInPublic #BuildInPublic #100Devs
- Continued learning the Prompt Engineering path from roadmap.sh.
- Explored and tested out various prompting methods — honestly, pretty fun and straightforward to follow once you get the hang of it.
- Also dove into AI Developer Roadmap on roadmap.sh, exploring a few new AI-related terms and concepts.
- Feels like a good mix of sharpening both my Node.js fundamentalsand AI curiosity today.
Day 57 of #100DaysOfCode #LearnInPublic #BuildInPublic #100Devs
- Prepped for a backend interview — revisited old questions, brushed up on fundamentals, and tried to recall tricky scenarios from past experiences.
- Wrapped up the day listening to some flute music — perfect chill-down after a tech-heavy week.

- Spent today exploring what’s fresh and trending in the AI market — checking new tools, SDKs, and agent frameworks.
- Considering upgrading to ChatGPT Plus or Claude Pro, just to stay ahead and experiment faster with premium models.
- Honestly, Facebook’s developer docs can be a maze at times — but once you get used to their structure, it starts making sense.
- plan out an actual integration flow (auth, data fetch, and posting) to test everything end-to-end.
Day 50–55 of #100DaysOfCode #LearnInPublic #BuildInPublic #100Devs
- Spent the last few days researching Facebook API integrations — figuring out how their ecosystem works (Graph API, permissions, tokens, and versioning).
- I’m wrestling with the question — how do large codebases scale without turning into a developer’s headache? I’ve read about microservices, but honestly, the complexity feels like a double-edged sword.
#100DaysOfCode #Backend #Scalability #MongoDB
Day 49 of #100DaysOfCode
- Designing MongoDB models with scalability in mind — accounting for unexpected growth.
- Refactoring and separating business logic to make the codebase more maintainable.
- Guarding against malicious dependency injections(supply chain attacks, not DI as a feature). Things like checking package integrity, monitoring dependencies, and using tools like `npm audit`, Snyk, Dependabot.
#100DaysOfCode #Backend #WebSecurity
Day 44–48 of #100DaysOfCode
- Deep dive into web application security.
- How backend apps can be hardened against phishing attacks(validation, sanitization, email link safety, rate-limiting).
- Debugging frontend feels like taking a walk after heavy backend lifting — lighter, but it teaches you the hidden power of small details.
#Frontend #Accessibility #SemanticHTML
Day 44 of #100DaysOfCode
- Spent time fixing frontend quirks — the old-school `<div soup>` vs shiny new semantic HTML elements
- How proper semantics boost accessibility and make the DOM feel less like chaos and more like a well-organized library.
- OAuth flows feel like a puzzle with hidden traps but once it clicks, it’s super rewarding. File handling in Node, on the other hand, is like plumbing — boring until you realize a leak (bad strategy) can flood your whole app.
#NodeJS #OAuth2 #XAPI #Multer #BuildInPublic
Day 42–43 of #100DaysOfCode
- Deep-dived into X.com’s OAuth 2.0 flow with PKCE and got a working demo app up and running for X APIs + authorization flows.
- Played with Node.js file modules and tried out different Multer strategies for handling uploads in efficient, real-world use cases.
- Both OAuth flows and AI behaviors remind me that docs only get you halfway — real understanding comes from breaking and fixing things yourself.
22.09.2025 17:25 — 👍 0 🔁 0 💬 0 📌 0- Worked on an **AI Foundry project**, diving into why AI models **hallucinate** or **ghost** during long, context-heavy conversations. Super eye-opening to trace the patterns behind these quirks.
#NodeJS #TwitterAPI #OAuth #AI #LLM #BuildInPublic
Day 39–41 of #100DaysOfCode
- Implemented **social authorization** and dug into Twitter APIs (v1.0a vs v2.0). Honestly, their complexity had me going in circles, but the experiments with the official docs paid off.
- It’s fascinating how a math concept can be the backbone of "understanding" in AI. Makes me realize how deep the math-AI connection really runs.
#AI #LLM #MachineLearning #MathInAI #BuildInPublic
Day 38 of #100DaysOfCode
- Read LLM Insiders and explored the concept of cosine similarity — one of the core mechanisms behind how LLMs reason and compare meanings.
- The workflow isn’t too far off from GitHub, just a matter of getting used to the GitLab way of doing things. I’ll keep digging into it tomorrow.
#WebDev #GitLab #OpenSource #100Devs #LearnInPublic #BuildInPublic
Day 37 of #100DaysOfCode
- Continued exploring GitLab — creating templates felt pretty similar to GitHub’s approach.
- Created a few issues, feature requests, and merge requests (basically GitLab’s version of PRs).
- First impressions matter, and GitLab feels like learning a cousin of GitHub. Tomorrow I’ll dive deeper into its collaboration features to see how it compares.

Day 36 of #100DaysOfCode
- Started exploring GitLab today. The look and feel are obviously different from GitHub, but it still feels a bit off for me right now.
- Just tinkered around the platform — nothing major coded, more about getting familiar with the environment.
- Tools like PostHog make analytics feel less intimidating — it’s like getting x-ray vision into how users interact with your app.
#WebDev #Analytics #PostHog #100Devs #LearnInPublic #BuildInPublic
Day 35 of #100DaysOfCode
- Explored different tracking and analytics strategies. Came across @posthog.com docs and got introduced to how product analytics can be set up.
- Set up basic event tracking and analytics with PostHog to test how it works in practice.
thanks bro
