Hi, I'm @siddharthjaswal,

who builds at scale
with Kotlin + Compose + AI Tooling
Experience
End-to-end ownership across discovery → architecture → delivery → adoption, collaborating directly with product and engineering.
Android Platform Architecture
Middleware design, multi-module monolith splits, shared SDK libraries, clean architecture at scale.
Performance Engineering
Cold-start optimization, ANR prevention, memory profiling, build time reduction, startup sequencers.
CI/CD & Release Engineering
Jenkins, Fastlane, automated quality gates, staged rollouts, zero-downtime release infrastructure.
Developer Experience
AI-assisted PR review, code generation pipelines, Claude/Cursor/Gemini tooling adopted by 15+ engineers.
Enterprise Client Delivery
Custom flows for Meesho, Uber, BigBasket, Flipkart — from PRDs to full-stack delivery.
Reliability & Security
99%+ crash-free migrations, SSL pinning, R8 hardening, biometric auth, staged rollout safeguards.
Selected Initiatives
Shadowfax
Mobile Middleware & API Platform
Designed the middleware abstraction layer for Android teams integrating with Shadowfax microservices. Improved payload efficiency across GraphQL and REST.
→ 40% API response-time improvement at large scale.
Shadowfax
Android CI/CD & Quality Engineering
Built shared platform tooling adopted by all engineers: Jenkins and Fastlane pipelines, release automation, quality gates, and rollout safeguards.
→ Release cycles from weeks to days, zero critical production issues.
Shadowfax
AI-Enhanced Developer Experience
Rolled out AI-assisted PR review, code generation, and documentation workflows using Claude, Cursor, and Gemini.
→ Adopted by 15+ engineers; ~40% reduction in development cycles.
Open Source
I build in public — turning real problems into tools and products people can actually install, use, and contribute to.
Travlogue
Creator & Maintainer · 2026
A collaborative travel-planning web app — plan multi-country trips day by day with friends, with live transit, maps, weather and an AI trip assistant.
An end-to-end product I designed, built and run at travlogue.in — a real-time, collaborative trip planner where friends co-author a day-by-day itinerary: activities, flights/trains/stays, and expenses with automatic split & settlement, backed by an AI assistant that drafts plans and turns forwarded booking emails into itinerary items. Full-stack and shipped solo: a Next.js/React frontend, a FastAPI/Postgres backend, push-to-main CD, and an offline-first PWA so the plan still works on the road.
- Real-time collaboration: shared trips, per-card comments, presence and live editing — friends plan together instead of over a group chat.
- AI built in: a trip assistant plus an email→itinerary importer (Claude) that parses booking confirmations into structured plans.
- Travel-grade detail: per-leg routing + ETAs (great-circle arcs for flights), live flight status, weather + air quality, maps, and Wikipedia place context.
- Shipped like a product: Google OAuth, Stripe plans, public trip sharing + one-click clone, an offline-first PWA, and an admin analytics + error-monitoring layer.
→ Used by me and my friends to plan real multi-country trips — planning that used to sprawl across chats and docs now lives in one shared, fun place.
TripleCaptain
Creator & Maintainer · 2026
A Fantasy Premier League companion — track your season week by week with a live dashboard, mini-league analytics, and an AI assistant that audits your squad.
A full-stack Next.js app I built and run at triplecaptain.in: enter your FPL manager ID and get a live view of your team — gameweek points as matches play out, a pitch view with captain badges and bench points, mini-league standings with progression charts, and fixture difficulty ratings five gameweeks ahead. On top of the data sits “the Gaffer”, an AI auditor that reviews your squad and suggests a captain, formation, transfers, chip timing and differential picks. Shipped solo with a typed, Zod-validated FPL data layer and a Vitest + Playwright test suite.
- Live gameweek dashboard: points update as matches play out, with a pitch view of your XI, captain and bench points.
- Mini-league analytics: standings with filtering and pagination, plus progression charts tracking the top managers all season.
- “The Gaffer” AI auditor: captain, formation, transfer and chip-timing suggestions and differential picks from your squad and fixtures.
- Built like a product: typed FPL data layer with Zod, a Vitest + Testing Library + Playwright test suite, and Vercel deploys.
→ Live at triplecaptain.in — I use it to track my own mini-leagues every gameweek.
LogPose
Creator & Maintainer · 2026
An open-source network inspector for Android — an IntelliJ / Android Studio plugin that reads your app's HTTP traffic without the logcat pain.
A two-part tool that fixes a daily annoyance: reading HTTPS traffic in logcat. An on-device OkHttp interceptor emits each request/response as one atomic, structured JSON transaction — so concurrent calls never interleave or mismatch bodies — and a custom IntelliJ tool window renders it as a filterable, collapsible, copy-as-cURL inspector. Built to solve a real pain on a 10M+ user app, then open-sourced and published.
- One atomic structured transaction per request — fixes logcat interleaving and mismatched bodies under concurrency.
- Live in-flight requests with a ticking timer; collapsible JSON tree plus a real editor with code folding.
- One-click filter bar, copy-as-cURL, multipart/S3 upload metadata, on-device header redaction, light & dark theme.
- Shipped like a product: GitHub Actions CI with the JetBrains Plugin Verifier, plugin signing, JitPack + Marketplace.
→ Adopted by teammates and integrated into production behind a single debug-only interceptor line.
Contributions
A year of shipping in public — every square is a day at the keyboard.

What colleagues say
“Siddharth is one of the most gifted engineers I have worked with. His grasp over mobile app development is not just extremely sound from a technical perspective but his design sense and a remarkable ability to put himself in the user's shoes helps him excel where a lot of android engineers of his experience level can't.”
Dipesh Mittal
CTO @ DrDroid (YC W23) · Managed Siddharth directly
“If there's one thing I learned working with Siddharth, it's that speed and stability don't have to be trade-offs. He has an engineer's discipline paired with a builder's urgency, and that combination is hard to find.”
