Hands-on delivery
I design and implement APIs, application services, database changes and frontend integrations. I am comfortable owning a feature from requirement to release.
Employer overview
Afzal Ahmed
Hands-on Senior Full Stack .NET Engineer & Technical Lead
I build, improve and support business-critical software across the full delivery lifecycle. My strongest experience is in C#, ASP.NET Core, SQL Server, Azure and modern web applications, backed by 15+ years working across finance, legal technology, SaaS and digital delivery.
I bring senior judgement without pretending to know everything. I remain hands-on, learn continuously, investigate carefully and work well with developers, product teams and operational users.

What you can expect
Useful from discovery through production
I am most valuable where business context, existing systems and practical delivery matter as much as writing new code.
Production responsibility
I investigate incidents, trace root causes, tune SQL and application performance, and make corrective changes without losing sight of live users.
Modernisation with care
I improve legacy systems incrementally, balancing cleaner architecture with delivery risk, existing behaviour and the team’s capacity to maintain it.
Business understanding
I translate workflows, compliance needs and operational problems into software decisions rather than treating every requirement as a technical ticket.
Collaborative leadership
I contribute through architecture discussions, code reviews, pairing and clear communication while remaining open to evidence and ideas from others.
Continuous learning
I study and experiment outside delivery work, then document what I learn. New technology is evaluated through code and context, not adopted for novelty.

Proof of practice
What I build when I am learning
My personal portfolio is a laboratory, not a claim that every project is a live commercial product. I use realistic domains to practise architecture, workflows, security, testing and full-stack delivery in code that employers can inspect.
Property development
BuildEstate Pro
A source-backed exploration of modular enterprise software, CQRS, state machines, permissions, Angular and reusable platform foundations.
View case study →Healthcare workflowsClarityCare
A complex healthcare domain used to practise modelling, compliance-minded architecture, workflows and operational interfaces.
View project →Financial systemsLoan Investment Supermarket
A lending and investment exercise shaped by earlier commercial finance experience, calculations and multi-role workflows.
View project →My public engineering journal
I turn books, documentation, questions from work and hobby experiments into notes I can revise. Some topics deepen established skills; others document the beginning of an exploration.
Teaching and mentoring
I have supported colleagues through reviews, pairing and technical guidance. I also offer focused one-to-one mentoring, team sessions and code or architecture clinics.
