Hi, I'm Harshal Manerikar

Developer

I build scalable web applications end-to-end: polished UIs, production APIs, and ML tools that solve real business problems.

About

Who I am

I'm a developer who got tired of tutorials and started building real things. My journey started with Python scripts and data analysis, then expanded into web development when I realised that great software is only useful if people can actually reach it.

I've since built ML pipelines, Streamlit dashboards, and full-stack Next.js apps, always trying to ship something that solves a real problem, not just passes tests. I care deeply about code that other people can read, maintain, and improve.

What I'm up to

  • Interning as an Operations Intern at Yashuss, building offboarding workflows and process automation.
  • Authored an open-source baseline for Flower, the federated learning framework — PR open and under review by core maintainers.
  • Extending Documind: improving multi-provider LLM routing and reducing per-query cost.
  • Finishing my B.Tech at Manipal University Jaipur, graduating November 2026.

Journey

Where I've worked

Apr 2026Present

Yashuss Unlimited Business Solutions

Operations Intern

Built Threadlink, an end-to-end Python automation pipeline integrating Zoho Mail and Zoho CRM via OAuth 2.0 — modular 6-stage system processing 50 emails in 3.7s at 90% noise rejection. Authored a 4-pillar Email Centralization Implementation Plan covering MX/SPF/DKIM/DMARC verification, routing rules, role-based mail policies, and eDiscovery audit archiving. Designed a Day 0 → 30 → 90 offboarding lifecycle and 6-tier user-classification model.

Problem

Extracting insights from large document collections requires expensive custom engineering or poor off-the-shelf tools that don't handle mixed formats or nuanced Q&A.

Solution

End-to-end RAG (Retrieval-Augmented Generation) platform built with FastAPI and React. Users upload documents and ask natural-language questions answered by OpenAI or Gemini.

Key Features

  • Intelligent document Q&A across PDF, DOCX, and TXT formats
  • Multi-provider LLM support: OpenAI and Gemini, switchable per query
  • 1,000+ document uploads handled with 99.9% uptime
  • Automated CI/CD pipeline deployed on Render.com

React.jsTypeScriptPythonFastAPIRAG / LangChainOpenAI APIGemini APIRender.comCI/CD pipelineMicroservices
Challenges faced
  • Balancing accuracy, latency, and cost trade-offs across multiple LLM providers
  • Designing reliable RAG retrieval logic for varied document structures
  • Building a microservices architecture solo without over-engineering it

Problem

Warehouses operating in isolation hold either too much or too little stock, driving up costs and creating shortage risk. Manual rebalancing is slow, error-prone, and unable to react to changing demand.

Solution

Predictive inventory optimization platform that mines warehouse and order data to forecast demand, calculate inventory pressure, and recommend optimal stock transfers between locations.

Key Features

  • Forecasts demand and surfaces inventory imbalances across 8 warehouses and 32 SKUs
  • Stock Pressure Index (SPI) algorithm with transfer-optimization logic
  • Interactive dashboard with KPI tracking, demand forecasts, and what-if scenario simulation
  • Identified ₹15,250 in potential cost savings; reduced shortage exposure by 25%

Tech Stack

PlotlyStreamlitPythonPandasNumPyPredictive Analytics
Challenges faced
  • Designing an SPI metric that balances current stock, reorder thresholds, and predicted demand into a single actionable signal
  • Building transfer logic that respects same-category constraints across distributed warehouses
  • Translating analytical outputs into a stakeholder-facing dashboard non-technical users can act on

Trader Behaviour Analysis

Complete

Problem

Crypto trader performance shifts dramatically with market sentiment, but the patterns behind those shifts are obscured by noisy, high-volume trade data and lack of structured behavioural segmentation.

Solution

Data-driven analysis pipeline merging Hyperliquid trader data with the Bitcoin Fear & Greed Index to surface how sentiment regimes affect win rates, risk-taking, and trader behaviour.

Key Features

  • Cleaned and timestamp-aligned raw trader data with daily sentiment encoding
  • Statistical testing across sentiment regimes to validate behavioural shifts
  • Trader segmentation via clustering to identify heterogeneous response patterns
  • Found that sentiment affects win rates and risk expression more than median profitability

Tech Stack

JupyterPythonPandasscikit-learnStatistical TestingClustering
Challenges faced
  • Aligning two datasets with different timestamp granularities (per-trade vs daily)
  • Avoiding overfitting in segmentation given limited regime samples
  • Distinguishing genuine behavioural shifts from random variance in noisy market data

FlowSocial

In Progress

Problem

Traditional social platforms centralise all user data on company servers, creating massive privacy risks and making regulatory compliance (GDPR, HIPAA) nearly impossible.

Solution

Federated learning architecture where ML models train locally on each device. Only encrypted gradient updates are shared with the server; raw user data never leaves the client.

Key Features

  • Privacy-preserving personalised content recommendations
  • Federated model training across distributed nodes
  • GDPR / HIPAA / CCPA compliant by design
  • Architecture supports cross-institutional collaboration without data sharing

Tech Stack

Challenges faced
  • Handling heterogeneous and incomplete data across federated nodes
  • Maintaining model accuracy without centralised training data
  • Aligning complex technical architecture with clear user-facing outcomes

FedHT Baseline — Federated Nonconvex Sparse Learning

Open

Framework

Flower (flwrlabs/flower)

Leading open-source federated learning framework, originated at the University of Oxford.

Contribution

Authored the FedHT baseline for Flower, re-implementing Fed-HT and FedIter-HT (Tong et al., 2021, Federated Nonconvex Sparse Learning) in Python. Replicated synthetic and MNIST experiments across 100 simulated clients with non-IID data partitioning. Documented full reproducibility for downstream researchers. Reviewed by core maintainers.
