Pranjal Sailwal CS graduate, 2026 | Dehradun, India pranjalsailwal09@gmail.com | github.com/sailwalpranjal | linkedin.com/in/pranjal-sailwal/ | pranjalsailwal.com SUMMARY ------- I build products end to end: from the question worth asking to the thing that ships. Heading toward technical product and programme work, plus the consulting and implementation roles next to it. EDUCATION --------- Graphic Era Hill University, B.Tech, Computer Science & Engineering (Jul 2022 – Jul 2026) Provisional certificate issued July 2026; the degree is awarded at the next convocation. CGPA 7.36/10 over eight semesters, 185 credits earned, every subject passed. Coursework: Data Structures and Algorithms, Database Management Systems, Operating Systems, Computer Networks, Software Engineering. EXPERIENCE ---------- Python Programming Internship, Yantra Byte (Jan 2026 – Apr 2026) - Completed a Python programming internship of 3 months. The certificate states the duration and a completion date of 1 April 2026. PROJECTS -------- Growth Intelligence Lab (2026) - https://growth-campaign-funnel-intelligence.vercel.app - Found that 98.1% of the cost increase happened after the click, using a three-factor bridge (CPM, CTR, conversion) with no reconciliation residual, on a campaign that spent 19.2x more. - Built the analysis, backend API and dashboard on 100% public data, with 44 tests, segment fragility checks, z-tests with confidence intervals and a prioritised backlog of five experiments. Stack: Python, FastAPI, JavaScript, HTML, Render, Vercel AetherScan (2026) - https://aether-scan.vercel.app - Built the async FastAPI backend (53 route handlers) that pulls from 11 documented air-quality data sources through HTTPX. - Scored every reading for freshness, distance, sensor type and validity, and combined sources with a confidence that falls as they disagree; a missing value shows as unavailable, never as a guess. - Wrote the data-quality method, the source registry and a limitations file that states what the platform cannot do. Four-person team. Stack: FastAPI, Python 3.11, SQLAlchemy, NumPy, HTTPX, Next.js 14, TypeScript, SQLite Appwrite Migration Guard (2026) - https://github.com/sailwalpranjal/appwrite-migration-guard - Built amg, a Go command-line tool that inventories an Appwrite project and reports PASS, WARN or BLOCK with a reason for every finding; 8 commands run against live Appwrite Cloud. - Caught 11 of 11 planted changes in a live regression pass with no false positives, and made it never collect passwords, emails or environment variables, which a test checks. Stack: Go, GitHub Actions, Appwrite NitroDB (2026) - https://github.com/sailwalpranjal/NitroDB - Built a single-node embedded key-value store in Java 21: write-ahead log, SSTables, leveled compaction, crash recovery and snapshot-isolated reads (MVCC). - Verified it with 68 unit and integration tests and 42 JCStress concurrency outcomes with none failing; benchmarked with JMH. - Wrote the design before the code and a claim-by-claim verification matrix after it, and documented the limits: one node, no replication, no compression. Stack: Java, Shell scripting NeuroTract (2026) - https://neurotract-kappa.vercel.app - Built a web workstation for diffusion MRI: dataset validation, preprocessing, tensor and fibre fitting, probabilistic tractography and connectome graph metrics, on a FastAPI back end with a Next.js and Three.js viewer. - Streamed job progress live with server-sent events and stored checksums, parameters, the random seed and software versions beside every result so a run can be reproduced; 31 pytest tests. Stack: Python, FastAPI, Next.js, TypeScript, Three.js Geodesic Flow and Spectro-Geodesic Explorer (2025) - https://github.com/sailwalpranjal/geodesic-flow-visualizer - Built a WebAssembly engine in C++ that computes geodesic flow, Christoffel symbols and curvature on parametric surfaces in real time, with 4th-order Runge-Kutta integration and adaptive stepping. - Built a second explorer that couples wavelength-dependent refraction to curvature across 10 surfaces and 12 wavelengths, and published 2 preprints on ResearchGate. Stack: C++, WebAssembly, JavaScript, HTML Also built: SyncState; Spectral Monte Carlo Path Tracer; SecureHost Control Suite. PUBLICATIONS ------------ - AetherScan: A Quantum-Classical Hybrid Platform for Heterogeneous Air Quality Sensor Fusion and Real-Time Environmental Intelligence (2026, ResearchGate preprint) - Implementation and Performance Analysis of a Spectral Monte Carlo Path Tracer with Physical Optics Simulation and Adaptive Variance Reduction (2025, ResearchGate preprint) - Geodesic Flow Computation on Parametric Surfaces via WebAssembly: A Differential Geometry Engine with Adaptive Numerical Integration (2025, ResearchGate preprint) - Wavelength-Resolved Geodesic Propagation on Parametric Surfaces: Coupling Differential Geometry with Spectral Dispersion (2025, ResearchGate preprint) TECHNICAL SKILLS ---------------- FastAPI, Python, SQLAlchemy, NumPy, HTTPX, Next.js, TypeScript, SQLite, Java, Shell scripting, React, Yjs, WebRTC, Supabase, Clerk, C++, BVH acceleration, Monte Carlo integration, Spectral rendering, Three.js, Go, GitHub Actions, Appwrite, JavaScript, HTML, Render, Vercel, WebAssembly, C#, .NET, WPF, PowerShell. CERTIFICATIONS -------------- 71 certificates, each with a credential ID, including Career Essentials in Project Management (Microsoft) Managing Project Stakeholders (LinkedIn Learning)
