Practical guides
Solve a task, step by step.
Worked examples with sample inputs, expected results and checks you can repeat. Choose a task, then use the product manual for the detailed controls.
Make a failed request reproducible
Check a fictional JSON body, URL values, identifiers and time units before sharing a report.
Build a useful field report
Connect site photos to a location, an observation and a clear follow-up.
Plan a realistic teaching week
Turn one syllabus outcome into five sessions and track what students actually completed.
Understand notification history
Check what notification previews can preserve and why some messages cannot be recovered.
About
Software engineering with a product mindset.
My work sits between product design and implementation: understand the workflow, reduce unnecessary complexity, then build the software so it remains dependable in everyday use.
I’m Baishalya Roul, known online as Baisalya. This is my official home for software, practical guides and public profiles.
I work primarily with Flutter and Android, and I also build Windows and web experiences around the products I ship. The current software in this repository spans developer tooling, shop operations, construction workflows, teacher tools, notification history, and field documentation.
A recurring theme across these products is ownership: ordinary files where possible, offline or local-first workflows where they matter, and product surfaces that explain what the software actually does rather than hiding behind feature lists.
A quick view of the builder behind these products.
Practical first
Start from the real workflow and build around the job the software needs to finish.
Local where it matters
Use offline and local-first patterns when reliability, ownership, or field use makes them the better fit.
Release-minded
Treat documentation, validation, platform behavior, and recovery as part of the product — not cleanup after coding.

Engineering
Engineering choices shaped by the work, not a technology checklist.
I work across product structure, application behavior, local data, platform delivery, and release hardening. The emphasis changes by product, but the goal stays the same: software that is understandable, recoverable, and dependable in everyday use.
Application engineering
Cross-platform product delivery
Flutter-based applications for Android and Windows, with platform behavior treated as part of the product rather than as a final packaging step.
- Flutter & Dart application architecture
- Android interaction and release surfaces
- Windows desktop workflows and distribution
Data & resilience
Offline and local-first systems
Products such as DevDesk, ShopPilot, Construction ERP, and NotiVault are designed around local ownership, offline continuity, recovery, or device-first storage where the workflow calls for it.
- SQLite and device-local persistence
- Backup, restore, recovery, and migration thinking
- Ordinary-file workflows where appropriate
Workflow design
Operational software, not isolated screens
I structure interfaces around the work that has to move through them: billing, inventory, project operations, field evidence, teaching tools, API workspaces, and documentation.
- Task and information-flow modelling
- Dense desktop and touch-first mobile surfaces
- Clear states, actions, and recovery paths
Release engineering
Shipping includes the reliability work.
Validation scripts, documentation, privacy/support surfaces, platform-specific release checks, and regression protection are treated as engineering deliverables.
- Automated release-content validation
- Regression and reference-integrity checks
- Manuals, support, privacy, and release surfaces
Working stack
Tools are selected around the product boundary.
No percentage bars or arbitrary proficiency scores — these are the technologies and engineering areas visible in the software being built here.

Describe the workflow first
Start with the problem the software needs to solve.
For a product question, choose the product below. For a new build, share the target platform, the workflow that matters, and the constraint that cannot be ignored.
Use the product selector so the message arrives with the right context.
What should become faster, clearer, safer, or easier to recover?
