About
I'm Shashank Sangule, the engineer behind DivWeavers.
I'm a senior mobile and full-stack product engineer working across mobile applications, product interfaces, backend systems, integrations, practical AI features, and production delivery.
I work directly with startups, product teams, and software agencies, including on products and codebases that already exist.
An independent engineering practice, operated by me.
DivWeavers is the professional home for my independent product engineering work.
Clients work directly with me, so product questions, technical decisions, implementation, debugging, and delivery stay close to the engineer doing the work.
Areas of work
Product responsibilities that cross the stack.
I am most useful when the outcome depends on more than one isolated screen or ticket.
Mobile product engineering
Flutter, React Native, native platform integrations, authentication, notifications, subscriptions, releases, and inherited apps.
Frontend product engineering
React, Next.js, TypeScript, product interfaces, frontend architecture, performance, and maintainable delivery.
Backend and data
Supabase, PostgreSQL, APIs, authentication, storage, realtime behavior, serverless functions, and data workflows.
AI product integration
LLM APIs, structured extraction, OCR, embeddings, semantic search, orchestration, validation, and fallback behavior.
Production and release work
Debugging, failure handling, deployment, store releases, operational constraints, and practical handoff.
Existing codebases
Investigation, stabilization, feature delivery, and proportionate changes inside systems another team built.
From full-stack development to product ownership.
My full-stack foundation taught me to think beyond the screen currently being worked on. Frontend and mobile decisions connect to APIs, data models, authentication, state, integrations, releases, and failure handling.
Senior frontend work broadened that responsibility into architecture, product feasibility, review, debugging, performance, and maintainability. DivWeavers continues that progression through direct ownership of product outcomes.

Ownership where product behavior and engineering overlap.
Understanding an inherited product before changing it
Owning features that cross interface, API, data, and integration boundaries
Finding root causes behind difficult production symptoms
Turning product intent into practical, maintainable delivery
A rewrite should be a conclusion, not a reflex.
Inherited systems are normal. I work with Flutter, React Native, React, Kotlin, Swift, Supabase, and API-backed applications where documentation or architecture may be incomplete.
My first step is to understand the system, its constraints, and the evidence before recommending major changes.
How I think
Engineering principles
Understand before rebuilding
Investigate the system and its constraints before recommending major change.
Communicate risk early
Make unknowns, dependencies, and delivery risks visible before they become surprises.
Prefer practical architecture
Use the simplest structure that handles the product's real constraints and stays understandable.
Build for production
Include failure handling, state, permissions, deployment, and recovery in the engineering work.
Explain trade-offs clearly
Connect technical recommendations to risk, effort, maintainability, and product impact.
Leave the system understandable
Aim for a professional handoff that another engineer can safely continue.
Direct, visible, and compatible with your process.
I can work independently without disappearing. Founders, CTOs, and agencies can expect concise communication, evidence-based estimates, early risk discussion, independent problem solving, and a clean handoff without unnecessary rewrite pressure.
Selected work
Products that show the work in context.
SettleTab
SettleTab is a live Android app for itemized shared bills. People can scan a receipt or enter items manually, correct the bill, assign individual and shared purchases, calculate what each person owes, and share a read-only result.
Tare
Tare is a mobile habit reflection app that saves original check-ins, proposes structured fields for user review, and uses recorded history for progress views and insight paths.
Need engineering support inside an existing delivery model?
App Rescue covers inherited product problems. Agency Partners covers white-label and delivery support inside an agency workflow.
