Show HN: ProfileHunt – Portfolio builder for product managershttps://profilehunt.in/Hi HN! I built ProfileHunt (https://profilehunt.in/), a portfolio builder specifically designed for product managers.The ProblemBreaking into product management is notoriously difficult, especially for career switchers. Unlike designers or developers who can showcase visual work or code, PMs struggle to demonstrate their skills tangibly. Traditional resumes don't capture the full scope of product thinking, problem-solving approaches, or impact metrics that define great product work. Most PMs end up using generic website builders (Notion, Squarespace, Wix) that aren't tailored to showcase PM-specific artifacts like PRDs, roadmaps, product teardowns, or impact metrics. The result? Portfolios that feel generic and fail to tell the compelling story hiring managers want to see.What ProfileHunt DoesProfileHunt helps product managers create portfolios that actually showcase what makes them great at the role:PM-focused templates: Structured sections for case studies, product teardowns, metricsDec 29, 2025 8:52 AM

Show HN:Built a 200k-edge market knowledge graph to filter false dip-buy signalshttps://news.ycombinator.com/item?id=46416991I’ve been experimenting with a graph-based approach to a classic trading problem: why most dip-buying strategies can’t tell the difference between a temporary overreaction and a genuine structural collapse.Most systems treat a −5% move the same regardless of context. My hypothesis was that where a company sits in the market’s structure matters more than the price move itself.The engineering ideaI built a knowledge graph of the U.S. public markets with ~207k edges across ~21 relationship types, organized into four layers:Operational: supply-chain relationships (SUPPLIES_TO, PRODUCES)Flow: ETF and institutional ownership plumbingSocial: board interlocks (SHARES_DIRECTOR_WITH)Environmental: geography / competitionFor each layer, I compute centrality scores using PageRank-style methods (with inverse-degree weighting to avoid ETF super-nodes dominating).These structural features are then combined with basic price/volume context and fed into a tree-based model (XGBoost) to rank stocks after Dec 29, 2025 2:56 AM

Show HN: DeviceGPT – AI-powered Android device monitor with real datahttps://news.ycombinator.com/item?id=46415639I built DeviceGPT to solve a problem I faced as an Android developer: device monitoring tools either show confusing raw data or use estimates instead of real measurements.What makes DeviceGPT different:• 100% Real Data - Uses actual Android system APIs (BatteryManager, ActivityManager, real network tests). No estimates or simulations.• AI-Powered Explanations - Share device data to ChatGPT/Claude to get plain English explanations. No more wondering what "CPU usage 85%" actually means.• Privacy Guardian - Detects keyloggers, screen recorders, SSL hijacking, and spyware that could compromise your device.• Global Leaderboard - Compare your device's performance with millions of users worldwide.• Research-Based Power Analysis - Implements latest academic research (2020-2025) for accurate power consumption measurements.Tech Stack: - Kotlin + Jetpack Compose - Firebase (leaderboard, analytics) - ChatGPT/Claude API (AI explanations) - Real Android system APIsI'd love feedback on: 1.

I thought they needed time to think, before they spoke. But they couldn't stay in the TV studio for hours and days. They needed a place online where they could share their thoughts, later when done thinking. There wasn't any good software for this, so I started coding.

You either clone gigabytes locally or click through the file browser one by one.So I built WALL·E Gallery. Use existing collections or Paste a repo URL→ instant gallery.How it works: - Fetches repo tree via GitHub (no cloning) - Proxies thumbnails (~50KB instead of 10MB originals) - Works with private repos too (with GitHub token)Infinite scroll, search, dark mode, mobile friendly, self-hostable.

Show HN: Terminal Aesthetic Productivity Apphttps://app.kensho.zoneHey HN,I keep building things and failing at launch. This time I built something that enforces the discipline I lack: a productivity system that physically blocks you from working when you've done too much focus without rest.What it does: - Focus timer + meditation tracker + task manager in one terminal-aesthetic interface - Hard 10:1 focus:rest enforcement — work 100 minutes, you OWE 10 minutes of rest before the timer unlocks again - Task completion requires reflection logs (1 reflection per 5 tasks) — no backlog journaling allowed - ASCII progress bars, monospace everything, brackets for every action: `[ START_FOCUS ]` - No gamification, no streak anxiety, no "you can do it!" cheerleading Why I built it: I'd work 4-hour blocks, burn out by Wednesday, then doomscroll for 3 days. Every productivity app let me keep going. I needed something that would stop me and enforce recovery.The aesthetic is intentional — brutalist terminal UI to strip out dopamine triggers.

Show HN: Doculearn – How much of your Gen-AI code do you understand?https://doculearnapp.comHey HN,I built Doculearn after watching my team (and myself) ship faster than ever with Claude, Cursor, and Copilot—but understand less and less of what we were actually deploying.The vibe coding problem:We'd accept a 200-line AI suggestion, tests pass, PR approved, merged. Two weeks later: "Wait, how does this authentication flow work again?" No one knew. The person who approved it just trusted the AI. The person who merged it moved on to the next feature.Sound familiar?What Doculearn does:It watches your GitHub activity and automatically generates flashcards from YOUR code. Not generic "what is a closure?" cards—actual flashcards about the authentication middleware you merged yesterday, the API endpoint you refactored, the algorithm you copy-pasted from Claude.

Essentially, the job market today is a DDOS attack on HR departments, where spam applications prevent the candidates they actually want from being seen or reviewed. LLMs excel at summarization and translation tasks, so we sit as a platform between candidates and hiring managers to summarize your career history and translate that into the language of a specific hiring manager or recruiter.What you can do in the beta:- Interview prep with Athena (AI).

What I learned building "comfortable" LED strip lightinghttps://news.ycombinator.com/item?id=46390875I built a small workspace lighting setup using LED strips and ended up learning more than I expected. On paper it was simple: stick a strip somewhere, add a diffuser, done. In practice, the stuff that mattered wasn’t the spec sheet—it was power delivery, optics, and human perception.A few notes that surprised me:Power planning > “just buy a bigger PSU.” Long runs behave like distributed loads. Voltage drop shows up as uneven brightness, and on RGB/RGBW it can show up as color shift (“white” gets warmer at the far end). The fix isn’t only wattage—it’s where you feed power, wire gauge, and connector losses.Diffusion is not cosmetic. Without enough distance or diffusion, you get hotspots and glare. A cheap milky diffuser in an aluminum channel gets you most of the way there, but what helped the most was increasing LED-to-diffuser distance (depth of the channel) rather than chasing “premium” diffusers.Indirect beats direct for comfort.
