Chartered accountants and tax advisory firms in India operate under tight compliance deadlines and massive document volumes. SignBooks was created to replace legacy spreadsheets and fragmented messaging apps with an all-in-one operations power center.
As Lead Full Stack Developer, Abhishek architected end-to-end modules for client onboarding, automated document workflows, role-based access controls, and real-time activity audit logs. The system leverages Node.js micro-services paired with PostgreSQL to handle multi-tenant data isolation with strict security protocols.
The result was a transformative operational lift: partner firms reported a 45% reduction in turn-around time for compliance filings and seamless digital collaboration between senior auditors and clients.
“SignBooks streamlined complex tax firm workflows into intuitive digital pipelines, empowering firms to scale without administrative overhead.”
