Senior .NET Developer | ERP & SQL Server Expert
An imported item’s purchase price is only part of its inventory cost. Transport and other related expenses also need to be allocated accurately.
This Landed Cost Allocation screen is part of the custom ERP import module I developed using VB.NET (http://VB.NET) and Microsoft SQL Server.
It allows users to select an import shipment receipt, allocate each expense across received items, and review the allocated total and remaining difference before finalizing.
In this example, a PKR 22,000 transport expense is distributed across three items in proportion to their base values, with no unallocated balance.
The module supports Base Value, Basic Unit Quantity, and Manual allocation methods, helping businesses handle different costing requirements within an integrated inventory and accounting workflow.
Need a similar import-costing module or an enhancement to your existing .NET business software? Let’s discuss your requirements.

system designed specifically for optometrists, ophthalmologists, and eyewear
retail stores. The platform combines clinical eye refraction management with
optical product inventory and a fully integrated point-of-sale environment,
enabling clinics and optical shops to manage patient prescriptions, eyewear
products, and sales operations from a single centralized system.
The system maintains a
complete history of patient eye prescriptions, including refractive
measurements such as Sphere, Cylinder, Axis, and additional optical parameters
used in professional eye testing. Eyecon incorporates intelligent logic to
analyse stored prescription data and assist practitioners in determining
appropriate lens power values based on previous refraction records and standard
ophthalmic practices.
Beyond the clinical
environment, Eyecon includes a comprehensive optical retail module that manages
frames, ophthalmic lenses, contact lenses, sunglasses, and eyewear accessories.
The integrated inventory engine tracks product availability, product specifications,
and stock movement while seamlessly connecting with the POS module used for
retail sales.
The POS module allows
optical stores and clinics to sell eyewear products while automatically linking
patient prescriptions with the appropriate lenses and frames. Sales
transactions update stock levels in real time while maintaining accounting
integration for financial tracking.
Built as a cloud-connected
Windows desktop application, Eyecon allows multiple branches or clinics to
operate with a centralized database hosted on a remote server. This
architecture ensures secure data storage, synchronized operations, and
accessibility across different clinic locations.

Enterprise-Grade ERP Payroll System with Automated Tax
Engine, Compliance Reporting & Full Accounting Integration.
This Payroll Module is a fully integrated
ERP-based payroll and statutory compliance system designed for medium to large
organizations. It covers complete employee master management, configurable
salary structures, allowance and deduction policies, automated withholding tax
calculation using fiscal-year annualization (July–June), and dynamic slab-based
tax configuration.
The system generates structured monthly
salary sheets using a master–detail architecture with posting controls,
approval workflow, and automatic accounting integration. It intelligently
tracks YTD salary and tax deductions to ensure accurate mid-year adjustments
and regulatory compliance.
In addition to payroll processing, the
module includes a comprehensive Withholding Tax Register (paid/unpaid
tracking), Tax Payment Voucher system with CPR and bank instrument management,
and automated generation of statutory withholding tax certificates (Rule 42
compliant).
The entire module is built with strong
database normalization, audit trail control, and finance integration, making it
suitable for manufacturing, trading, and corporate environments requiring
accuracy, transparency, and compliance-driven payroll automation.
Withholding Tax Register:
This module produces the Payroll
Withholding Tax Register, showing employee-wise taxable salary, tax deducted,
tax paid, and outstanding tax payable with flexible paid/unpaid filtering.
The Withholding Tax Register module is
designed for statutory reporting and tax compliance by maintaining a clear,
auditable trail of payroll income tax deductions and payments. It generates an
employee-wise register that includes key identity fields (Employee Name, CNIC,
NTN), transaction references (date, type, voucher no., serial no.), and
complete tax impact (Taxable Amount, Tax Deducted, Tax Paid, and Tax Payable).
The register supports practical operational
controls such as filtering by employee and cost center, and it
provides separate views for Paid vs Unpaid tax. For paid entries,
it applies a date range to produce period-based compliance reports, while for
unpaid entries it intelligently lists all outstanding liabilities regardless of
date to help finance teams track pending tax payments.
By linking tax entries with tax sections
and enforcing consistent section mapping, this module ensures accurate
classification, improved reconciliation, and readiness for government filings
and internal audits.

AI Agents & Automation That Ship | Voice AI, LLMs, .NET
Not every automation needs an LLM. A B2B business was receiving purchase orders from retailers through SPS Commerce.
Someone on the team then checked stock by hand, retyped each order into Sage 50 as a sales order, and kicked off fulfillment.
We built a platform on ASP.NET (http://ASP.NET) Core and C# that handles it end to end.
→ Purchase orders come in through SPS Commerce automatically
→ Stock and order details are validated before anything is created
→ Sales orders land in Sage 50 without retyping
→ Anything odd is flagged as an exception instead of quietly slipping through Less manual work across the whole order lifecycle, cleaner data, and orders that keep moving without anyone copying fields between screens.
I build a lot of AI agents now. But the first question on every scoping call is still the same.
Does this need judgement, or does it just need wiring? Half the time it's wiring.

Most AI features never leave the demo.
The model is rarely the problem. It's everything around it: messy data, old .NET code nobody wants to touch, and no clear answer to "what does this actually save us?"
On CasePath we skipped the chatbot and aimed AI at one job caseworkers hated: writing case notes.
Result: 90% less documentation time. Supervisor decisions 83% faster. 20% more caseload with zero new hires.
What made it work:
Pick one painful task, not a whole "AI strategy"
Put AI inside the app people already use
Measure hours saved before writing a line of code
If you run a .NET product and AI is on your roadmap, message me. One call and I'll tell you where it'll pay off, and where it won't.

Project Title: ASAPP CRM — AI-Powered Real Estate Lead Management
Short Description:
A role-based real estate CRM that centralizes lead capture, assignment, follow-ups, communication, reporting, and AI-powered sales workflows.
Project Description:
I led the full-stack development of ASAPP CRM, a real estate sales platform designed to help teams manage leads, communication, follow-ups, and daily operations from one centralized system.
The Challenge
Real estate teams were receiving leads from multiple channels and relying on disconnected tools for assignment, communication, and follow-ups. This made it difficult to track lead activity, maintain accountability, and respond to opportunities on time.
The Solution
I helped create a scalable CRM platform featuring:
• Role-based dashboards for administrators, managers, and agents
• Automatic lead capture from social channels
• Round-robin and manual lead assignment
• Complete activity history when leads are transferred
• SMS, WhatsApp, and email communication from the lead profile
• Follow-up calendar for overdue, upcoming, and completed activities
• Real-time lead pipeline and conversion monitoring
• AI-powered lead scoring and sales forecasting
• Next-best-action recommendations
• AI chatbot for lead qualification
• Context-aware email and SMS drafting
• Mobile access and live lead-count widgets
The Result
ASAPP CRM gave sales teams a clearer view of their pipeline, improved lead ownership, and made follow-ups easier to manage. Its automated follow-up workflow also helped reduce the missed-meeting ratio by 2%.
My Role:
Lead Full-Stack Developer
Skills:
CRM Development, TypeScript, Node.js, Express.js, MongoDB, REST APIs, RBAC, AI Integration, Workflow Automation

Building an AI-Powered Platform for Conversations Across Languages
What happens when two people need to communicate but don’t speak the same language?
I am working on an AI-powered multilingual communication platform designed to make conversations easier across language barriers.
The platform allows a user to speak or type a message in their preferred language. It processes the input, translates the message, and returns the result as both readable text and generated audio.
When automated translation is not enough for a complex or sensitive conversation, the experience can also provide access to additional human language support.
My contribution focused on strengthening the technical foundation behind this experience, including:
Voice-to-text processing
Multilingual translation
Text-to-speech generation
Native-script transcription
Backend performance
Concurrent request handling
Web and mobile consistency
Testing and feedback workflows
One of the biggest challenges was ensuring that the product did more than simply list multiple languages as “supported.”
It also needed to:
Process different writing systems
Produce understandable native-script output
Maintain translation and transcription quality
Generate consistent audio responses
Handle multiple language-processing tasks efficiently
Provide a reliable experience across web and mobile devices
I approached the platform as a complete communication system rather than a collection of disconnected AI features.
Translation quality, speech processing, backend architecture, accessibility and human support all needed to work together to create a useful experience.
Over the next few weeks, I’ll share more about how I approached multilingual transcription quality, backend scalability and speech integration while protecting client confidentiality.
This case study contains recreated visuals and anonymized technical information. The client identity, product name, original interface, user information and proprietary workflows have been intentionally excluded.
What do you think is the biggest challenge when building a multilingual product: accuracy, response time or accessibility?
