kaustav kalra — software engineer focused on systems and design

i like building software where technical depth and product design are treated as the same problem.

my work has moved across backend systems, developer tooling, computer vision, healthcare software, AI-assisted workflows, and mobile products and is usually somewhere between what a system does internally and what using it actually feels like.

selected systems

HydraScan project system card

on-device ML recovery intelligence for iOS. HydraScan analyzes biomechanical movement using pose estimation and deterministic scoring, processing 33-point pose data at 120Hz and computing 50+ biomechanical metrics.

engineering notes / architecture

Tech: Swift, SwiftUI, MVVM, SwiftData, HealthKit, QuickPose, MediaPipe, SIMD3

  • Scores squat, hip hinge, posture, balance, range of motion, and asymmetry.
  • Uses NaN-safe joint-angle calculations and fallback logic for incomplete pose data.
  • Built as a 12K+ line SwiftUI/MVVM client across 59 files.
  • Includes a reusable 700+ line SwiftUI design system powering 20+ views.
  • Designed as a privacy-first recovery app with deterministic scoring and on-device movement analysis.

BeliefGuard AI execution control project card

repository-aware execution control for AI-assisted coding. BeliefGuard makes model assumptions explicit, grounds them against codebase evidence, and gates patch generation before workspace mutation.

engineering notes / architecture

Tech: TypeScript, VS Code Extension API, Zod, Vitest, LLM APIs

  • Extracts AI agent assumptions into a typed Repo Belief Graph.
  • Uses a Confidence-to-Action Gate to route changes to proceed, inspect, ask, or block.
  • Integrates LLM plan extraction, workspace scanning, evidence grounding, Zod validation, structured patch generation, and per-file diff review.
  • Validates behavior with Vitest, property-based tests, and benchmark scenarios.
  • Built around responsible AI-assisted development, output validation, and developer trust.

PatientConnect360 healthcare coordination project card

industry-sponsored healthcare coordination platform for patients, caregivers, clinicians, and admins. Backend query improvements and pagination reduced large-dataset query time and network transfer by ~95%.

engineering notes / architecture

Tech: React, Vite, Node.js, Express, Prisma, PostgreSQL, Recharts

  • Built role-based healthcare workflows across patients, caregivers, clinicians, and admins.
  • Implemented RBAC, OTP verification, authenticated sessions, caregiver/MPOA linking, privacy controls, and audit visibility.
  • Developed scheduling, messaging, medication tracking, vitals, notifications, feedback, and visit lifecycle workflows.
  • Built admin analytics dashboards with KPI tracking, DAU monitoring, searchable logs, filters, and pagination.
  • Optimized large-dataset query time and network transfer by 95% through pagination and backend query improvements.

more work

swipeable civic discovery and action platform. A deployed civic engagement product that helps users discover, understand, and act on local policy issues.

Tech: Next.js, TypeScript, Prisma, PostgreSQL, Redis, Clerk, Claude

  • Built feed, saved, profile, discussion, and issue-tracking workflows.
  • Implemented Redis-backed state consistency and low-latency APIs.
  • Built personalized ranking using interests, district matching, geography, and engagement velocity.
  • Integrated Claude-powered summarization for dense civic issue content.

Play Music to Tune Up Your Mood

published AI/ML research project. A machine-learning project using Spotify API data to classify songs by emotional tone, reaching 76 percent classification accuracy.

Tech: Python, Keras, scikit-learn, Pandas, NumPy, Seaborn, Matplotlib, Spotify API

  • Built a neural network for music emotion classification.
  • Used feature preprocessing, scaling, label encoding, K-Fold cross validation, and confusion-matrix reporting.
  • Published findings on acousticness, valence, tempo, and emotional tone classification.
